MUXOUT
RF Charge Pump Output. This is normally connected to a loop filter that drives the input to an external VCO.
RF Charge Pump Ground.
Input to the RF Prescaler. This small signal input is normally taken from the VCO.
Complementary Input to the RF Prescaler.
Analog Ground for the RF Synthesizer.
This multiplexer output allows either the RF or IF lock detect, the scaled RF or IF, or the scaled reference fre-
quency to be accessed externally.
Reference Input. This is a CMOS input with a nominal threshold of V
DD
/2 and an equivalent input resistance of
100 k
. This input can be driven from a TTL or CMOS crystal oscillator.
Reference Output.
Digital Ground for the Fractional Interpolator.
Serial Clock Input. This serial clock is used to clock in the serial data to the registers. The data is latched into the
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 three 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
seven latches, the latch being selected using the control bits.
Connecting a resistor between this pin and ground sets the minimum charge pump output current. The relationship
