SA7016 Datasheet, PDF (2/18 Pages) NXP Semiconductors – 1.3GHz low voltage fractional-N synthesizer

Philips Semiconductors
1.3GHz low voltage fractional-N synthesizer
Product specification
SA7016
GENERAL DESCRIPTION
The SA7016 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 1.3 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 RSET pin. Only passive loop filters could be used; the charge
pump operates within a wide voltage compliance range to provide a
wider tuning range.
