GENERAL DESCRIPTION
The SA8027 BICMOS device integrates programmable dividers,
charge pumps and phase comparators to implement phase-locked
loops. 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. The main divider is a fractional-N divider with
programmable integer ratios from 512 to 65535.
Separate power and ground pins are provided to the charge pumps
and digital circuits. The ground pins should be externally connected
to prevent large currents from flowing across the die and causing
damage. V
DDCP
must be equal to or greater than
V
DD
.
The charge pump current (gain) is fully programmable, while I
SET
is
set by an external resistance at the R
SET
pin (refer to section 1.5,
Main Output Charge Pumps and Fractional Compensation
Currents)
.
The phase/frequency detector charge pump outputs allow
for implementing a passive loop filter.
