INTEGRATED CIRCUITS DATA SHEET UMA1018M Low-voltage dual frequency synthesizer for radio telephones Product specification Supersedes data of November 1994 File under Integrated Circuits, IC03 1995 Jun 27 Philips Semiconductors Product specification Low-voltage dual frequency synthesizer for radio telephones UMA1018M The principal synthesizer operates at RF input frequencies up to1.25 GHz the auxiliary synthesizer operates at 300 MHz. The auxiliary loop is intended for the first IF or to transmit offset loop-frequency settings. Each synthesizer has a fully programmable reference divider. All divider ratios are supplied via a 3-wire serial programming bus. FEATURES * Low current from 3 V supply * Fully programmable RF divider * 3-line serial interface bus * Second synthesizer to control first IF or offset loop frequency Separate power and ground pins are provided to the analog and digital circuits. The ground leads should be externally short-circuited to prevent large currents flowing across the die and thus causing damage. Digital supplies VDD1 and VDD2 must also be at the same potential. VCC must be equal to or greater than VDD (i.e. VDD = 3 V and VCC = 5 V for wider tuning range). * Independent fully programmable reference dividers for each loop, driven from external crystal oscillator * Dual phase detector outputs to allow fast frequency switching * Integrated digital-to-analog converter * Dual power-down modes. The principal synthesizer phase detector uses two charge pumps, one provides normal loop feedback, while the other is only active during fast mode to speed-up switching. The auxiliary loop has a separate phase detector. All charge pump currents (gain) are fixed by an external resistance at pin ISET (pin 14). Only passive loop filters are used; the charge-pumps function within a wide voltage compliance range to improve the overall system performance. An on-chip 7-bit DAC enables adjustment of an external function, such as the temperature compensation of a crystal oscillator in Global System for Mobile communications (GSM). APPLICATIONS * 900 MHz mobile telephones * Portable battery-powered radio equipment. GENERAL DESCRIPTION The UMA1018M BICMOS device integrates prescalers, programmable dividers, and phase comparators to implement two phase-locked loops. The device is designed to operate from 3 NiCd cells, in pocket phones, with low current and nominal 5 V supplies. QUICK REFERENCE DATA SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.

The high frequency divider circuits use bipolar transistors, slower bits are CMOS. Divider ratios (512 to 131 071) allow a 1 MHz phase comparison with a 500 MHz RF input, and a 10 kHz phase comparison with a 1.25 GHz RF input. FUNCTIONAL DESCRIPTION Principal synthesizer Programmable reference and main dividers drive the principal PLL phase detector. Two charge pumps produce phase error current pulses for integration in an external loop filter. A hardwired power-down input PON (pin 9) ensures that the dividers and phase comparator circuits can be disabled. The reference and main divider outputs are connected to a phase/frequency detector that controls two charge pumps. The two pumps have a common bias-setting current that is set by an external resistance. The ratio between currents in fast and normal operating modes can be programmed via the 3-wire serial bus. The low current pump remains active except in power-down. The PRI input (pin 6) drives a pre-amplifier to provide the clock to the first divider stage. The pre-amplifier has a high input impedance, dominated by pin and pad capacitance. The circuit operates with signal levels from 50 mV up to 1995 Jun 27 4 Philips Semiconductors Product specification Low-voltage dual frequency synthesizer for radio telephones UMA1018M The high current pump is enabled via the control input FAST (pin 1). By appropriate connection to the loop filter, dual bandwidth loops are provided: short time constant during frequency switching (FAST mode) to speed-up channel changes and low bandwidth in the settled state (on-frequency) to reduce noise and breakthrough levels. Serial programming bus A simple 3-line unidirectional serial bus is used to program the circuit. The 3 lines are DATA, CLK and E (enable). The data sent to the device is loaded in bursts framed by E. Programming clock edges and their appropriate data bits are ignored until E goes active LOW. The programmed information is loaded into the addressed latch when E returns inactive HIGH. Only the last 21 bits serially clocked into the device are retained within the programming register. Additional leading bits are ignored, and no check is made on the number of clock pulses. The fully static CMOS design uses virtually no current when the bus is inactive. It can always capture new programmed data even during power-down of main and auxiliary loops. The principal synthesizer speed-up charge pump (CPPF) is controlled by the FAST input in synchronization with phase detector operation in such a way that potential disturbances are minimized. The dead zone (caused by finite time taken to switch the current sources on or off) is cancelled by feedback from the normal pump output to the phase detector thereby improving linearity. An open drain transistor drives the output pin LOCK (pin 20). It is recommended that the pull-up resistor from this pin to VDD is chosen such that the value is high enough to keep the sink current in the LOW state below 400 A. The circuit can be programmed to output either the phase error in the principal or auxiliary phase detectors or the combination from both detectors (OR function). The resultant output will be a current pulse with the duration of the selected phase error. By appropriate external filtering and threshold comparison an out-of-lock or an in-lock flag is generated. However, when either principal synthesizer or auxiliary synthesizer or both are powered-on, the presence of a TCXO signal is required at pin 8 (fXTAL) for correct programming. Data format Data is entered with the most significant bit first. The leading bits make up the data field, while the trailing four bits are an address field. The UMA1018M uses 6 of the 16 available addresses. These are chosen to allow direct compatibility with the UAA2072M integrated front-end. The data format is shown in Table 1. The first entered bit is p1, the last bit is p21. Auxiliary synthesizer The auxiliary synthesizer has a 14-bit main divider and an 11-bit reference divider. A separate power-down input AON (pin 19), disables currents in the auxiliary dividers, phase detector, and charge pump. The auxiliary input signal is amplified and fed to the main divider. The input buffer presents a high impedance, dominated by pin and pad capacitance. First divider stages use bipolar technology operating at input frequencies up to 300 MHz; the slower bits are CMOS. The auxiliary loop phase detector and charge pump use similar circuits to the main loop low-current phase comparator, including dead-zone compensation feedback. The trailing address bits are decoded on the inactive edge of E. This produces an internal load pulse to store the data in one of the addressed latches. To ensure that the data is correctly loaded on first power-up, E should be held LOW and only taken HIGH after having programmed an appropriate register. To avoid erroneous divider ratios, the pulse is not allowed during data reads by the frequency dividers. This condition is guaranteed by respecting a minimum E pulse width after data transfer. The corresponding relationship between data fields and addresses is given in Table 2. The auxiliary reference divider is clocked on the opposite edge of the principal reference divider to ensure that active edges arrive at the auxiliary and principal phase detectors at different times. This minimizes the potential for interference between the charge pumps of each loop. 1995 Jun 27 5 LAST IN PROGRAMMING REGISTER BIT USAGE FIRST IN p21 p20 p19 p18 p17 p16 ../.. p2 p1 ADD0 ADD1 ADD2 ADD3 DATA0 DATA1 ../..

The internal current is scaled by the external resistance (Rext) at pin ISET, similar to the charge pumps. The nominal full-scale current is 2 x ISET. The output current is mirrored to produce a full-scale voltage into a user-defined ground referenced resistance, thereby allowing optimum swing from power supply rails within the 2.7 to 5.5 V limits. The band gap reference voltage at pin ISET is temperature and supply independent. The DAC signal is monotonic across the full range of digital input codes to enable fine adjustment of other system blocks. The typical settling time for full-scale switching is 400 ns into a 12 k // 20 pF load. DAC functionality is neither tested nor guaranteed on UMA1018M versions with the /S1 suffix. The action of the control inputs on the state of internal blocks is defined by Table 5. 1995 Jun 27 It should be noted that in Table 5, PON and AON can be either the software or hardware power-down signals. The dividers are ON when both hardware and software power-down signals are at logic 1. When either synthesizer is reactivated after power-down the main and reference dividers of that synthesizer are synchronized to avoid the possibility of random phase errors on power-up. 7 Philips Semiconductors Product specification Low-voltage dual frequency synthesizer for radio telephones UMA1018M LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices. There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these cases reflow soldering is often used. If wave soldering cannot be avoided, the following conditions must be observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). * The longitudinal axis of the package footprint must be parallel to the solder flow and must incorporate solder thieves at the downstream end. Reflow soldering Even with these conditions, only consider wave soldering SSOP packages that have a body width of 4.4 mm, that is SSOP16 (SOT369-1) or SSOP20 (SOT266-1). Reflow soldering techniques are suitable for all SO and SSOP packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. METHOD (SO OR SSOP) During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Wave soldering SO Repairing soldered joints Wave soldering techniques can be used for all SO packages if the following conditions are observed: Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds at 270 to 320 C. * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow. * The package footprint must incorporate solder thieves at the downstream end. 1995 Jun 27 16 Philips Semiconductors Product specification Low-voltage dual frequency synthesizer for radio telephones UMA1018M DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
