Function

Digital CMOS supply voltage. Note: VDD and VCC must be equal!

PLL charge pump output

Analog / bipolar ground, Charge pump ground and Digital CMOS ground (VSS)

Used for bipolar prescaler, charge pump and Digital CMOS

RF frequency input

AC coupling is required.

Analog / bipolar supply and Charge pump supply

Used for bipolar prescaler, input buffer and chargepump

Note: VDD and VCC must be equal!

Multi-functional output (Open-drain)

3-Wire bus input: Clock

Clock input of the serial control interface with CMOS Schmitt-Trigger input stage

3-Wire bus input: Data

Data input of the serial control interface withCMOS Schmitt-Trigger input stage.The serial

data are read into the addressed internal shift register with the positive edge of CLK

3-Wire bus input: Enable

Enable input of serial control interface with CMOS Schmitt-Trigger input stage. When

EN=H the input signals CLK and DA are disabled. When EN=L the serial control interface

is enabled. The received data bits are transmitted into the addressed registers with the

positive edge of EN

Reference frequency input

Input with highly sensitive preamplifier. With small input signals AC coupling must be set

up, whereas DC coupling can be used for large input signals
