Description
Input of tuning voltage amplifier
First crystal input is the active pin at the oscillators
Second crystal input is the internal ground
Data input
Clock input of the I2C bus
Band buffer (open collector) outputs for up to 10 mA
Band buffer (open collector) outputs for up to 10 mA
Chip address selection pin
Supply voltage, typical 5.0 V
Symmetric HF inputs from local oscillator
Ground
Output of the tuning voltage amplifier. Needs an external NPN with pull–up
resistor to drive the varicaps
