It is fully implemented on chip. The tuning circuit of the VCO consisting of spiral inductors and varactor diodes is on chip, too. Therefore no additional external components are necessary. The nominal center frequency of the VCO is 690 MHz. The oscillator signal is fed both, to the synthesizer divider chain and to the power amplifier. The overall division ratio of the asynchronous divider chain is 64, a 10.78 MHz crystal should be used. The phase detector is a Type IV PD with charge pump. The passive loop filter is realized on chip. 3.4.2 Crystal Oscillator The crystal oscillator operates at 10.78 MHz. The output frequency at CLKOUT (pin 6) is 2.7 MHz, this is the crystal frequency divided by 4. 3.4.3 Power Amplifier The VCO frequency 688-694 MHz is divided by 2 and fed to the power amplifier. The Power Amplifier can be switched on and off by the signal at DATA (pin 5). Table 3-3 DATA (pin 5) 1) Low Open2), High3) 1) Low: 2) Open: 3) High: Power Amplifier OFF ON Voltage at pin < 0.5 V Pin open Voltage at pin > 1.5 V The Power Amplifier has an Open Collector output at PAOUT (pin 9) and requires an external pull-up coil to provide bias. The coil is part of the tuning and matching LC circuitry to get best performance with the external loop antenna. To achieve the best power amplifier efficiency, the high frequency voltage swing at PAOUT (pin 9) should be twice the supply voltage. The power amplifier has its own ground pin PAGND (pin 8) in order to reduce the amount of coupling to the other circuits. Wireless Components 3-7 Specification, March 2001 TDA 5103A preliminary Functional Description 3.4.4 Low Power Detect The supply voltage is sensed by a low power detector. When the supply voltage drops below 2.15 V, the output LPD (pin 10) switches to the low-state. To minimize the external component count, an internal pull-up current of 40 A gives the output a high-state at supply voltages above 2.15 V. The output LPD (pin 10) can either be connected to DATA (pin 5) to switch off the PA as soon as the supply voltage drops below 2.15 V or it can be used to inform a micro-controller to stop the transmission after the current data packet. 3.4.5 Power Modes The IC provides three power modes, the POWER DOWN MODE, the PLL ENABLE MODE and the TRANSMIT MODE. 3.4.5.1 Power Down Mode In the POWER DOWN MODE the complete chip is switched off. The current consumption is less than 100nA. 3.4.5.2 PLL Enable Mode In the PLL ENABLE MODE the PLL is switched on but the power amplifier is turned off to avoid undesired power radiation during the time the PLL needs to settle. The turn on time of the PLL is determined mainly by the turn on time of the crystal oscillator and is typically less than 1 msec, depending on the crystal. The current consumption is typically 3.5 mA. 3.4.5.3 Transmit Mode In the TRANSMIT MODE the PLL is switched on and the power amplifier is turned on too. The current consumption of the IC is typically 7 mA when using a proper transforming network at PAOUT, see Figure 4-1. 3.4.5.4 Power mode control The bias circuitry is powered up via a voltage V > 1.5 V at the pin PDWN (pin 1). When the bias circuitry is powered up, the pin DATA is pulled up internally. Forcing the voltage at the pin DATA low overrides the internally set state. The principle schematic of the power mode control circuitry is shown in Figure 3-5.

Application Hints on the crystal oscillator As mentioned before, the crystal oscillator achieves a turn on time less than 1 msec. To achieve this, a NIC oscillator type is implemented in the TDA 5103A. The input impedance of this oscillator is a negative resistance in series to an inductance. Therefore the load capacitance of the crystal CL (specified by the crystal supplier) is transformed to the capacitance Cv. -R L f, CL Cv IC Cv = 1 1 +2L CL Formula 1) CL: crystal load capacitance for nominal frequency : angular frequency L: inductance of the crystal oscillator Example: Assume a crystal frequency of 10.78 MHz and a crystal load capacitance of CL = 12 pF. The inductance L is specified within the electrical characteristics at 10.78 MHz to a value of 11 H. Therefore C6 is calculated to 7.5 pF.

Design hints on the buffered clock output (CLKOUT) The CLKOUT pin is an open collector output. An external pull up resistor (RL) should be connected between this pin and the positive supply voltage. The value of RL is depending on the clock frequency and the load capacitance CLD (PCB board plus input capacitance of the microcontroller).

Supply-voltage dependency: 2 dB / V at 3 V with reference to 3 V. A smaller load impedance reduces the supply-voltage dependency. Temperature dependency: +1 dB at -25c and -3 dB at +85C with reference to +25C. A higher load impedance reduces the temperature dependency. 2) Power amplifier is switched off at 2.15 V Wireless Components 5-6 Specification, March 2001
