3.2 Pin Definition and Functions
Pin No.
Symbol
Function
1
VDD
Digital CMOS supply voltage. Note: VDD and VCC must be equal!
2
CP
PLL charge pump output
3
GND
Analog / bipolar ground, Charge pump ground and Digital CMOS ground (VSS)
Used for bipolar prescaler, charge pump and Digital CMOS
4
LO
RF frequency input
AC coupling is required.
5
VCC
Analog / bipolar supply and Charge pump supply
Used for bipolar prescaler, input buffer and chargepump
Note: VDD and VCC must be equal!
6
MFO
Multi-functional output (Open-drain)
7
CLK
3-Wire bus input: Clock
Clock input of the serial control interface with CMOS Schmitt-Trigger input stage
8
DA
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
9
EN
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
10
RI
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
