FastLock Output. For connection of parallel resistor to the loop filter. (See Section 1.3.4
FASTLOCK MODES description.)
Charge Pump Output. For connection to a loop filter for driving the input of an external VCO.
Charge Pump Ground.
Analog Ground.
RF Prescaler Complementary Input. A bypass capacitor should be placed as close as possible to
this pin and be connected directly to the ground plane. The complementary input can be left
unbypassed, with some degradation in RF sensitivity.
RF Prescaler Input. Small signal input from the VCO.
Analog Power Supply Voltage Input. Input may range from 2.3V to 5.5V. Bypass capacitors should
be placed as close as possible to this pin and be connected directly to the ground plane. V
CC1
must equal V
CC2
.
Oscillator Input. This input is a CMOS input with a threshold of approximately V
CC
/2 and an
equivalent 100k input resistance. The oscillator input is driven from a reference oscillator.
Digital Ground.
Chip Enable. A LOW on CE powers down the device and will TRI-STATE the charge pump output.
Taking CE HIGH will power up the device depending on the status of the power down bit F2. (See
Section 1.3.1 POWERDOWN OPERATION and Section 1.7.1 DEVICE PROGRAMMING AFTER
FIRST APPLYING V
CC
.)
High Impedance CMOS Clock Input. Data for the various counters is clocked in on the rising edge
into the 21-bit shift register.
Binary Serial Data Input. Data entered MSB first. The last two bits are the control bits. High
impedance CMOS input.
Load Enable CMOS Input. When LE goes HIGH, data stored in the shift registers is loaded into one
of the 3 appropriate latches (control bit dependent).
Multiplexed Output of the RF Programmable or Reference Dividers and Lock Detect. CMOS output.
