SA8016
2.5GHz 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
DDCP
must be greater than or equal to
V
DD
.
The charge pump current (gain) is set by an external resistance at
the R
SET
pin
.
Only passive loop filters could be used; the charge
pump operates within a wide voltage compliance range to provide a
wider tuning range.
