Description
- Ground for IF analog circuitry.
- This pin is to provide a bypass capacitor to the internal voltage supply and
bypass capacitor must be placed between this pin and IF analog GND(Pin
14). With a slight performance degradation, this pin may be NC.
I IF prescaler input. Small signal input from the VCO.
- Ground for IF digital circuitry.
O Internal IF charge pump output. For connection to a loop filter for driving
the input of an external VCO.
- Power Supply for IF charge pump. Must be ≥ VDDIF.
- Power supply voltage input for IF analog, IF digital, data interface, FoLD,
and oscillator circuits. Input may range from 2.7V to 3.6V. VDDIF must
equal VDDRF. Bypass capacitors should be placed as close as possible to
this pin and be connected directly to the ground plane.
- No Connect
