CIRCUIT DESCRIPTION SECTION 4 CIRCUIT DESCRIPTION 127( $ EORFN GLDJUDP RI WKH 5) DQG ORJLF XQLWV LV ORFDWHG RQ SDJH 4.2 SYNTHESIZER DESCRIPTION 4.2.
CIRCUIT DESCRIPTION The divide numbers are chosen so that when the VCO is operating at the correct frequency, the VCOderived input to the phase detector is the same frequency as the TCXO-derived input. The TCXOderived input is produced by the reference counter in IC1. This counter divides the 14.925 MHz TCXO frequency by 2388 to produce a 6.25 kHz input to the phase detector. Using a 6.25 kHz reference frequency allows channels to be changed in 6.25 kHz steps.
CIRCUIT DESCRIPTION ance matching on the output is provided by C15, L9, L10, C18, C19, and R99. The first IF signal is then fed to four-pole crystal filter FI3. This filter attenuates wideband noise, adjacent channels, frequencies resulting from intermodulation, and other frequencies close to the receive channel. frequency is low, the VCO-derived input to the phase detector is lower than the TCXO-derived input (or the phase lags the TCXO-derived input). Pin 15 of IC1 then pulses low and turns Q1 on.
CIRCUIT DESCRIPTION by the switching circuit consisting of D7 and other components (see Section 4.2.2) and applied to amplifier Q9. Power to this stage and also Q8 is the 7.5-volt battery supply switched by Q16 and Q17. This switch is controlled by the switched T5V supply. Therefore, when the transmit mode is selected, the TX5V supply goes high which causes the output of Q17 to go low and turn switch Q16 on. input signal to these transistors is high for narrow band channels.
CIRCUIT DESCRIPTION 4.4.3 POWER CONTROL (IC2A/B) from two external devices. They are 16K x 8 EEPROM IC304 and DTMF encoder IC303. Another serial port formed by XTXD and XRXD is used to transfer programming data to and from an external computer. This port is fed out of the transceiver on pins 6 and 7 of the accessory connector. Descriptions of the IC306 pins are located in Table 4-1.

CIRCUIT DESCRIPTION from IC113B. The data output signal on IC210, pin 1 is then applied to pin 24 of IC209 which is the input to one of the digitally controlled potentiometers in that device. The data modulation level is set during alignment and controlled by the logic. The output on pins 22 and 23 is then fed to IC201 where it is combined with the transmit audio signal (see Section 4.8.3). cut-off frequency is approximately 190 Hz.
CIRCUIT DESCRIPTION is provided by gate IC110 which is controlled by the SN_TR signal from pin 95 of the microprocessor. When this signal is high, the transmit data signal on pin 6 is selected is routed to the filter, and when it is low the receive data signal on pin 7 is routed to the filter. caused by high input levels from the internal or external microphone. The bias voltage to this stage and also to IC201A is produced by voltage divider R208/R207. 4.8.
BATTERY PACK AND CHARGER INFORMATION SECTION 5 BATTERY PACK AND CHARGER INFORMATION 5.1 BATTERY PACK • Repeated deep discharge. Recharging should take place soon after the low battery indication appears. This indication appears when the battery pack voltage drops to 6.3 volts which is approximately 1 volt per cell. Do not regularly continue operating the transceiver until it is completely nonfunctional. • Regularly recharging a battery after only light use. This may result in shortened operating time.
BATTERY PACK AND CHARGER INFORMATION The primary method used by these chargers to detect a fully charged battery is to sense the point at which the battery temperature begins increasing at a faster rate (∆T/∆t). This normally provides the first indication that the battery is fully charged. If this method does not indicate a charged battery, the charger also detects a negative change in battery voltage (minus ∆V) which also indicates a fully charged battery.
