Title: Data Sheet GC-IP200 Name of Document: 43500-DB-2-1-E-IP200.pdf 1 Overview The IP200 interpolation circuit is designed for connection to incremental position and angle measuring systems with sine-shaped output signals with a 90 phase shift. It can be operated at a large number of transducer systems working according to the most varied measuring principles. With a maximum interpolation rate of 200 the IC is capable to split the input signal period into up to 200 segments. A counter value can be output via parallel or serial interface, respectively. Different interfaces and flexible configuration types enable the use of the IP200 in single-chip interpolation systems, in microcontroller-based measuring devices and in multi-channel systems alike. Proprietary automatic gain and offset control, as well as the possibility of a analogue phase correction ensure a high measuring precision under industrial conditions. The integrated two-level measuring value trigger and the additional parallel high speed output makes the IC suitable for use in real time applications.

A third input signal serves as a reference signal for determining the zero or reference point of the scale. All the three input signals are processed as differential signals. 2.1 Analogue Signal Properties Difference Signal Sin = SinP-SinN Angle 0 Vdi ff Peak to Peak SinP SinN 90 Phase Shift Vdiff Peak to Peak CosP CosN Difference Signal Cos = CosP-CosN Figure 2 Differential Analogue Input Voltage1) Analogue Input Voltage VDiff (nominal) Input Range for VDiff Maximum Signal Offset Error Sine/Cosine Phase Shift 1) on pins SINP, SINN, COSP, COSN 2.2 500mV pp 1Vpp 0.8Vpp ... 1.2Vpp 100mV 90 (adjustable 10) Signal Correction The input signals are subject to a automatic gain and offset control patented by GEMAC. The amplitude controller is specified for a control range of 20% of nominal input voltage. The offset of the external signals must not exceed a value of 10% of nominal input voltage. The phase shift of the input signals can be statically adjusted by a external analogue potentiometer in a range of 10 (also refer to Application Notes 4300x-AN-3-0-E-IPx.pdf). A Chip Reset results in setting the gain-offset-controller to midscale. For achieving the best interpolation performance, the gain-offset-controller needs approximately 20 signal periods for reaching a steady state. Until this time, the input signal frequency must not exceed 50% of the specified maximum signal frequency (refer to chapter 4.4). All signal errors figures as a union in the IP200. In some special cases means decreasing of one signal error result in a wider permissible range of another signal error. For achieving the highest performance of the automatic gain-offset-controller, it is recommended to carefully adjust the phase shift on the connected sensor itself. This is important especially for high interpolation rates.

In some special applications, were the analogue sensor signal do not match the analogue front end (AFE) specification (nominal 1V pp), it is possible to connect the input signals to the Analogue Digital Converter inputs, bypassing the AFE. In this case, the conditioned sensor signals must be sine shaped with a amplitude of 2.4V pp centred around the ADC common mode level V0. The IP200 includes a on-chip reference voltage circuit that generates the V0 with a nominal voltage of 2.375V. 3.1 Input Circuit Rating VMAX = V0 + (VRP - VRN) Operating Range Reserve for Gain- and Offset Errors VNOM = 1.3 (VRP - VRN) (Nominal Amplitude Peak-Peak ) V0 = 1/2 (VRP + VRN) (Midscale Voltage) Reserve for Gain- and Offset Errors VMIN = V0 - (VRP - VRN) VRP : positive ADC-Reference Voltage VRN : negative ADC-Reference Voltage Figure 4 The following reference voltage levels appear on external pins: Positive Reference Voltage (VRP) Sine-ADC Positive Reference Voltage (VRP) Cosine-ADC Negative Reference Voltage (VRN) Sine-ADC Negative Reference Voltage (VRN) Cosine-ADC Midscale Voltage for external analogue circuitry Nominal amplitude Maximum voltage Minimum voltage Pin RSH RCH RSL RCL V0 UNOM UMAX UMIN Nominal Value 3.30V 3.30V 1.45V 1.45V 2.375V 2.405V 4.225V 0.525V For information about the tolerances see chapter Electrical Characteristics.

As described, the zero point can be generated using the REFP and REFN reference signal inputs, or it can be set via the serial interface. By activating the trigger input, measuring result can be kept in a 2-level deep buffer register in a manner asynchronous to the access via the interfaces. Simultaneously, the IP200 outputs the phase shifted square wave sequences (known by incremental measuring transducers) which can be counted in single or quadruple way. A synchronous reference pulse is generated when the angle of 0 (refer also to Fig. 2) is passed through and when the analogue differential input voltage between REFP and REFN exceed the positive comparator hysteresis level. If the differential input voltage is permanently above this level, the reference pulse is generated once during every signal period. A configuration bit can disable the generation of the reference pulse.

This means that the quantization errors (the so-called 1 errors) which are inevitable with A/D converters are superposed upon the speed-proportional A/B output signals. Analogue control systems must feature a corresponding low-pass behaviour when the IC is used in such systems.

The error signal is also generated if the input frequency is so high that the square-wave signals are unable to follow, and/or when the maximum input frequency is exceeded. The evaluation of the internal error sources is activated via an error mask register. The response of the square-wave outputs in the event of an error can also be configured via this register. The NERR and NRES pins can be connected in order to start a re-synchronisation process of the IC in the event of an error. If the error signal was activated, and/or if one of the error bits was set in the result register, the present measuring result and all the following results must be discarded. Following elimination of the cause of the error and a reset of the error bit, the reference point must once again be passed by for absolute value measurements! 4.3 Interpolation Rate The interpolation rate can be set at 200, 160, 100, 80, 50, 40, 25 and 20. The interpolation rate as defined for the purposes of this application is the number of increments into which one sine period of the input signal is divided. This also corresponds to the number of edge changes on the A/B output signals per input signal period. This means that the number of square-wave periods at the A and B outputs totals 1/4 of the interpolation rate per input signal period. In the event that a standard interpolation counter or quadrature decoder is connected to the A/B outputs, this must work in "quadruple evaluation" mode in order to achieve the full interpolation rate. 4.4 Interval Time / Maximum Input Frequency The interval time (IT) and the minimum edge distance tpp at the output signals, respectively, can be set in binary steps at values between 1/fosz and 128/fosz. In counter mode (the SPEED Bit in the CFG0 Register being set), the maximum input frequency totals fmax=fosc /96. In all the other modes, the maximum input frequency is limited by the minimum pulse distance at the output, where: fmax fosc: IR: IT: 0.9*fOSZ /(IRIT) < fosz/96 Clock frequency at Pin XA Activated Interpolation Rate Activated Interval Time The limit values are a maximum input frequency of aprox. 400kHz with a clock frequency of 40MHz on the one hand, as well as a guaranteed edge distance of 128s at the A/B signals with a clock frequency of 1MHz on the other. Between these two limits, a large number of specific systems can be adapted by selecting a suitable clock frequency and interval time of the IP200. These values apply on condition of an adjusted phase between the input signals and a steady state of the internal gain-offset-controller. Until this time, the input frequency must not exceed 50% of the specified maximum frequency.

In such a case, the minimum edge distance at the output (t pp) is then automatically set at 2048 / fosc while the measuring system is in standstill or at smaller input frequencies. Note that in the switching range to the automatic activation / deactivation of this filter, the A/B output signals are not speed-proportional in each case!

It is also possible to make a more detailed configuration of the IP200 IC over this interface than over hardware.

An additional 16-bit hold register series for the intermediate storage of the two MSB's during read accesses. An 8-bit address register is used for both read and write accesses. Writing into the IP200 takes place in a byteoriented manner whilst reading being a word-oriented process. Transmission itself is effected as 16-bit words. A read command triggers the pertinent data output during the next access. A single-byte command is executed at the end of data transmission. Up to 16 channels can be operated at this interface. The hardware address of the IC is determined by reading the DP(3:0) pins by a special command. 5.2.1 Signals The IP200 is a slave which evaluates commands and data received, but which is unable to start a communication process. The SPI protocol is executed via 4 lines: SDI SDO SCLK SEN Data input Data output (open drain), SDO also serving as the RDY signal Clock Enable The used SPI-protocol is not compatible to the usual micro controller- or DSP-families.

This takes place when the internal sequential control counter and the SYNC register have the same contents (synchronous mode) or when the ASYNC bit is set (asynchronous mode).

That's why the value at DATA(15:8) is undefined in the clock cycles 0 and 16. For external components the edges of OUTHIGH can be used to register the new valid data. The level on OUTHIGH show, which part of the 32-bit read value is active on the data pins (either LSB or MSB). A optional Strobe-Signal (on pin OREF) can be activated via TSTRB bit in the configuration register TSTCFG. To get out a desired read register on parallel port, it is necessary to read this register via serial interface first. EVERY other SPI access at any time can change the behaviour of parallel port. If the parallel interface be used solely as output port, please select carefully the corresponding attachment circuit of the configuration and the double function pins at the IP200. Please refer also application notes in the document 4300x-AN-3-0-E-IPx.pdf.

The active trigger edge is configured by the configuration bit TRGSLP (register CFG1). A read access to the register MVAL returns the "oldest" value of the trigger hold register. If the trigger register contains no active value, the current counter value returns in result of the read access. It is possible to save the results of two trigger events. While not both trigger register would be read out, all following trigger events are ignored. The TRGOVL bit in register MVAL is set, if a trigger event occurs and both trigger hold register contains valid data. Every SPI read access to the register MVAL releases one trigger hold register. Only if trigger hold register 1 is empty (TR1=0), a new trigger processing is possible. If the parallel interface used solely as output port, the pin CLRTRG must be operated to confirm the reading of one trigger event result. A logic "1" in the FROZEN bit out of the register MVAL indicates the source of the read value as trigger result. A logic "0" in this bit indicates the read access as normal read of the counter value. The actual state of the trigger is coded in the bits TR(1:0)of the status register (STAT).

Each source can be activated by the corresponding bit in the error mask register. With the LatchErr bit being activated, the individual error signals are stored until the next chip reset or until the next SPI ResetCount command (command 0x01) occurs, respectively. The logic OR function of the masked and stored error signals appears as a low active signal on pin NERR. With the HoldErr bit being active, the A, B and OREF outputs freeze in the current state on error case. The NERR and NRES pins can be shorted in order to re-synchronise the IC in the event of an error. The error signal is active for 8 system clocks in this case.

The status register STAT contains all error bits. The MVAL and CNT register contain logic combinations of counter relevant error bits: SENSERR = ADUOVL or BQLOW or OCOMP or GCOMP AMPERR = ADUOVL or BQLOW Sensor breakage error: Partial or complete tearing off of the connected sensor is detected in the IP200 at the time of occurrence. Thereafter, the automatic gain-offset-controller tries to compensate this error which, due to the large operating range of the gain-offset-controller, can lead to a situation where the cause of this error seems to have been eliminated.

It is essential to supply the IP200 with an external reset signal on pin NRES. This reset signal must appear low until 3ms after VDD rising to a voltage level of 4.75V.

Pin SDO/RDY goes to L, all register will be initialised with default values. The IC is operating a self-calibration, the configuration pins are read into the CFG0 register. Start of normal operation. Pin SDO/RDY goes to H (external pull-up required). The configuration register could be changed via SPI interface. The time between the rising edge of NRES and the rising edge of SDO/RDY, which means the end of the reset process, amount to approximately 1365 system clocks. 9.2 Configuration There are two different types of configuration possible: Configuration via input pins The register CFG0 will be configured via the input pins IR(2:0), IT(2:1), TRG/GFE and SDI/SPEED. All other registers are initialised with default values. Suitable for low-cost single-chip and standard applications. Configuration via SPI Pins DP(3:0) select SPI hardware address (for multi-channel systems only). Suitable for applications with SPI interface, for example microcontroller systems.

If a external counter unit connected to the A/B/OREF outputs is used, the time between sampling and output of resulting square waves totals 122 system clocks. Every 32nd system clock a new measurement result appears on the parallel data output.
