O
Fast Lock Switch Output. T his can be used to switch an external resistor to change the loop filter band-
width. T his will speed up locking of the PLL.
Charge Pump Output. T his is normally connected to a loop filter which drives the input to an external
V C O.
Charge Pump Ground
Analog Ground
Complementary Input to the RF Prescaler. T his point should be decoupled to the ground plane with a
small bypass capacitor. If this is not done then there will be some degradation in RF sensitivity.
Input to the RF Prescaler. T his small signal input is normally taken from the VCO.
Analog Power Supply. T his may range from 2.7V to 5.5V. Decoupling capacitors to the analog ground
plane should be placed as close as possible to this pin. AV

Reference Input. T his is a CMOS input with a nominal threshold of AV
DD
/2 and an equivalent input
resistance of 100k
.
T he oscillator input can be driven from a T T L or CMOS crystal oscillator.
Digital Ground.
Chip Enable. A logic low on this pin powers down the device and puts the charge pump output into
three-state mode. T aking the pin high will power up the device depending on the status of the power-
down bit F2.
Serial Clock Input. T his serial clock is used to clock in the serial data to the registers. T he data is
latched into the 21-bit shift register on the CLK rising edge. T his input is a high impedance CMOS
input.
Serial Data Input. T he serial data is loaded MSB first with the two LSBs being the control bits. T his
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.
T his multiplexer output allows either the Lock Detect, the scaled RF or the scaled Reference Frequency
to be accessed externally.
