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.

FEATURES
• Extremely low phase noise: L(f) = –101 dBc/Hz at 5 kHz offset at 800 MHz
• Low power
• Programmable Normal & Integral charge pump outputs: Maximum output = 10.4 mA
• Digital fractional spurious compensation
• Hardware and software power-down
• IDDsleep < 0.1 µA (typ) at VDD = 3.0 V
• Seperate supply for VDD and VDDCP
• Programmable loop filter bandwidth

APPLICATIONS
• 500 to 2500 MHz wireless equipment
• Cellular phones, all standards including:
    CDMA : IS95-B,C WCDMA
    3G : WCDMA / UMTS
    GSM : EDGE / GPRS
    TDMA : IS136 and EDGE
    GAIT : GSM and TDMA
• WLAN
• Wireless PDAs
• Satellite tuners and all other high frequency equipment
• Extreme fine frequency resolution applications
