119. 1 Synthesizer Refer to VHF Synthesizer Schematic Diagram on page 6B 22 The Fractional N Synthesizer uses a 16 8MHz crystal Y3761 to provide a reference for the system The LVFractN IC U3701 further divides this to 2 1MHz 2 225MHz and 2 4MHz as reference frequencies Together with C3761 C3762 C3763 R3761 and D3761 they build up the reference oscillator which is capable of 2 5ppm stability over temperatures of 30 to 85 C It also provides 16 8MHz at pin 19 of U3701 to be used by ASFIC and LVZIF The loop filter which consist of C3721 C3722 R3721 3722 and R3723 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through In achieving fast locking for the synthesizer an internal adapt charge pump provides higher current at pin 45 of U3701 to put synthesizer within the lock range The required frequency is then locked by normal mode charge pump at pin 43 Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C3701 to C3704 and triple diodes D3701 D3702 Two 3 3V square waves 180 deg out of phase are first multiplied by four and then shifted along with regulated 5V to build up 13 5V at pin 47 of U3701 LOCK LOCK U409 PIN 56 DATA U409 PIN 100 DATA FREFOUT FREF U3220 PIN 21 amp U404 PIN 34 CLOCK U409 PIN 1 CLK GND CSX U409 PIN 2 CEX U3701 STEERING LOW VOLTAGE LINE MOD IN U404 PIN 40 MODIN ERACTIONAL N

Block Diagram 4 1 Receiver Front End Refer to VHF Receiver Front End Schematic Diagram on page 6B 20 VHF Receiver Back End Schematic Diagram on page 6B 21 and VHF Transmitter Schematic Diagram on page 6B 24 The RF signal is received by the antenna and applied to a low pass filter For VHF the filter consists of L3531 L3532 C3532 to C3563 The filtered RF signal is passed through the antenna switch The antenna switch circuit consists of two PIN diodes D3521 and D3551 and a pi network C3531 L3551 and C3550 The signal is then applied to a varactor tuned bandpass filter The VHF bandpass filter comprises of L3301 L3303 C3301 to C3304 and D3301 The bandpass filter is tuned by applying a control voltage to the varactor diode D3301 in the filter The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the microprocessor Depending on the carrier frequency the DACRx will supply the tuned voltage to the varactor diodes in the filter Wideband operation of the filter is achieved by shifting the bandpass filter across the band The output of the bandpass filter is coupled to the RF amplifier transistor Q3302 via C3306 After being amplified by the RF amplifier the RF signal is further filtered by a second varactor tuned bandpass filter consisting of L3305 L3306 C3311 to C3314 and D3302 Both the pre and post RF amplifier varactor tuned filters have similar responses The 3 dB bandwidth of the filter

211. 303 and C348 and R301 form the termination for the crystal filter and the signal is coupled to one gate of U301 by C303 The IF amplifier is a dual gate MOSFET powered off of the 5 volt supply The first gate receives the IF signal as indicated previously The second gate receives a DC voltage from U302 which serves as an AGC control signal This signal reduces the gain of the IF amplifier to prevent overload of the IF IC U303 The gain can be varied from a maximum of 13 dB to an attenuation of 55 dB The output IF signal from U301 is coupled into U303 pin 3 via C306 R304 and L304 which provides matching for the IF amplifier and U303 The IF signal applied to pin 3 of U303 is amplified down converted filtered and demodulated to produce recovered audio at pin 27 of U303 This IF IC is electronically programmable and the amount of filtering which is dependent on the radio channel spacing is controlled by the microprocessor Additional filtering once externally provided by the conventional ceramic filters is replaced by internal filters in IF IC U303 The IF IC uses a type of direct conversion process whereby the externally generated second LO frequency is divided by two in U303 so that it is very close to the first IF frequency The IF IC U303 synthesizes the second LO and phase locks the VCO to track the first IF frequency The second LO is designed to oscillate at twice the first IF frequency because of the divide by two function in the IF

272. IC In the absence of an IF signal the VCO searches for a frequency or its frequency will vary close to twice the IF frequency When an IF signal is received the VCO locks onto the IF signal The second LO VCO is a Colpitts oscillator built around transistor Q301 The VCO has a varactor diode CR301 to adjust the VCO frequency The control signal for the varactor is derived from a loop filter consisting of components C308 C309 and R310 The IF IC U303 also performs several other functions It provides a received signal strength indicator RSSI and a squelch output The RSSI voltage is also used to control the automatic gain control AGC circuit at the back end The demodulated signal on pin 27 of U303 is also used for squelch control The signal is routed to U404 ASFIC where squelch signal shaping and detection takes place The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification 4 3 Automatic Gain Control Circuit The automatic gain control circuit provides automatic reduction of gain to prevent overloading of backend circuits This is achieved by lowering the voltage on one gate of U301 which will reduce the drain current in that part and lower its gain The Radio Signal Strength Indicator RSS 1 voltage signal for the IF IC 0303 is used to drive the AGC processing circuitry consisting of 8306 R307 R308 R309 C307 and 0302 As the received signal gets stronger the

Out Circuit Modulating Signal Figure 6 3 Frequency Generation Unit Block Diagram The Frequency Generation Circuitry is composed of two main ICs the Fractional N synthesizer U3701 and the VCO Buffer IC U3801 Designed in conjunction to maximize compatibility the two ICs provide many of the functions that normally would require additional circuitry The synthesizer block diagram illustrates the interconnect and support circuitry used in the region Refer to the relevant schematics for the reference designators The synthesizer is powered by regulated 5V and 3 3V which come from U3711 and U3201 respectively The synthesizer in turn generates a superfiltered 4 5V which powers U3801 In addition to the VCO the synthesizer must interface with the logic and ASFIC circuitry Programming for the synthesizer is accomplished through the data clock and chip select lines from the microprocessor A 3 3V dc signal from synthesizer lock detect line indicates to the microprocessor that the synthesizer is locked Transmit modulation from the ASFIC is supplied to pin10 of 03701 Internally the audio is digitized by the Fractional N and applied to the loop divider to provide the low port modulation The audio runs through an internal attenuator for modulation balancing purposes before going out to the VCO 6 10 Frequency Generation Circuitry 5
