Functions

1st ground for transmission system. 0V.

Output frequency that multiples the oscillation frequency of the transmission

system by 2, and outputs an open emitter.

Power supply pin for transmission VCO circuit. TXVCC = 2.7~3.6V.

Base pin of the transmission VCO transistor.

Emitter pin of the transmission VCO transistor. Set the current of the trans-

mission oscillation circuit by pull-down resistance.

2nd ground for transmission system. 0V.

Output the set current according to the difference in phase between Charge

Pump output pins in the PLL1(TX) system.

HiZ with the power supply turned off.

Power supply pin for the PLL system. VCC = 2.7~3.6V.

Crystal oscillator input

Inputs 4 to 25MHz output from the base oscillator to the XIN .

External crystal oscillator is available for oscillation.

Ground pin for the PLL system. 0V.

Extracts IF frequencies.

Judgment is made in a system turned on when the other system is turned off.

Operates at the rising edge of the clock pulse of the shift resistor.

Inputs serial data.

Inputs the reset pulse of 21 pulse counters.

Output the set current according to the difference in phase between Charge

Pump output pins in the PLL2(RX) system.

HiZ with the power supply turned off.

Ground for reception system. 0V.

Emitter pin of the reception VCO transistor. Set the current of the reception

oscillation circuit by pull-down resistance.

Base pin of the reception VCO transistor.

Power supply pin for reception VCO circuit. TXVCC = 2.7~3.6V.
