Function
Positive Power Supply for the RF1 Section. A 0.1
μ
F capacitor should be connected between
this pin and the RF1 ground pin, DGND
RF1
. V
DD
1 should have a value of between 2.7 V and
5.5 V. V
DD
1 must have the same potential as V
DD
2.
Power Supply for the RF1 Charge Pump. This should be greater than or equal to V
DD
.
Output from the RF1 Charge Pump. This is normally connected to a loop filter which, in
turn, drives the input to an external VCO.
Ground Pin for the RF1 Digital Circuitry.
Input to the RF1 Prescaler. This low-level input signal is normally taken from the RF1 VCO.
Complementary Input to the RF1 Prescaler of the ADF4208. This point should be decoupled to
the ground plane with a small bypass capacitor.
Ground Pin for the RF1 Analog Circuitry.
Oscillator Input. It has a V
DD
/2 threshold and can be driven from an external CMOS or TTL
logic gate.
Oscillator Output.
This multiplexer output allows either the IF/RF lock detect, the scaled RF, or the scaled
Reference Frequency to be accessed externally. See Table V.
Serial Clock Input. This serial clock is used to clock in the serial data to the registers. The
data is latched into the 22-bit shift register on the CLK rising edge. This input is a high
impedance CMOS input.
Serial Data Input. The serial data is loaded MSB first with the two LSBs being the control
bits. This input is a high impedance CMOS input.
Load Enable, CMOS Input. When LE goes high, the data stored in the shift registers is
loaded into one of the four latches, the latch being selected using the control bits.
Ground Pin for the RF2 Analog Circuitry.
Complementary Input to the RF2 Prescaler. This point should be decoupled to the ground
plane with a small bypass capacitor.
Input to the RF2 Prescaler. This low-level input signal is normally ac-coupled to the
external VCO.
Ground Pin for the RF2, Digital, Interface, and Control Circuitry.
Output from the RF2 Charge Pump. This is normally connected to a loop filter that drives
the input to an external VCO.
Power Supply for the RF2 Charge Pump. This should be greater than or equal to V
DD
.
Positive Power Supply for the RF2, Interface, and Oscillator Sections. A 0.1
