GENERAL DESCRIPTION
The SA8028 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 RF, IF, and reference
dividers. All divider ratios are supplied via a 3-wire serial
programming bus. The RF divider is a fractional-N divider with
programmable integer ratios from 33 to 509 and a fractional
resolution of 22 programmable bits (23 bits internal). A 2
nd
order
sigma-delta modulator is used to achieve fractional division.
Separate power and ground pins are provided to the charge pumps
and digital circuits. V
DDCP
must be equal to or greater than
V
DD
.
The ground pins should be externally connected to prevent large
currents from flowing across the die and thus causing damage.
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,
RF and IF Charge Pumps)
.
The phase/frequency detector charge
pump outputs allow for implementing a passive loop filter.
FEATURES
