TYPE NUMBER
SA80162.5GHz low voltage fractional-N synthesizer
GENERAL DESCRIPTION
The SA8016 BICMOS device integrates programmable dividers, charge pumps and a phase comparator to implement a phase-locked loop. The device is designed to operate from 3 NiCd cells, in pocket phones, with low current and nominal 3 V supplies.
The synthesizer operates at VCO input frequencies up to 2.5 GHz. The synthesizer has fully programmable main and reference dividers. All divider ratios are supplied via a 3-wire serial programming bus.
Separate power and ground pins are provided to the analog and digital circuits. The ground leads should be externally short-circuited to prevent large currents flowing across the die and thus causing damage. V
must be greater than or equal to V

.
The charge pump current (gain) is set by an external resistance at the R
pin. Only passive loop filters could be used; the charge
SET
pump operates within a wide voltage compliance range to provide a wider tuning range.
