NAME
FUNCTION
PIN
34
MOD-
PECL Modulus Control. A PECL low on MOD- sets the dual-modulus prescaler to divide by 32. A PECL
logic high sets the divide ratio to 33. Drive with a differential PECL signal with MOD+ (pin 33).
35
36
PLLIN+
PLLIN-
PECL Phase-Locked Loop Input. Drive with a differential PECL signal with PLLIN- (pin 36).
PECL Phase-Locked Loop Input. Drive with a differential PECL signal with PLLIN+ (pin 35).
37
PSOUT+
PECL Prescaler Output. Differential output of the dual-modulus prescaler. Used with PSOUT- (pin 38).
Requires PECL-compatible termination.

LO Tank Oscillator Input. Connect to an external LC tank with varactor tuning.
LO Internal Regulator. Bypass with a 100pF ceramic chip capacitor to GND.
LO Tank Oscillator Input. Connect to an external LC tank with varactor tuning.
Feedback Output. Control of external charge-pump transistor.
Voltage Drive Output. Control of external charge-pump transistor.
