GENERAL DESCRIPTION
The SA8026 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, auxiliary 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
R
SET
pin
.
Passive loop filters could be used; the charge pump
operates within a wide voltage compliance range to provide a wider
tuning range.
