FS8107E Low Power Phase-Locked Loop IC

Princeton Technology Corp. reserves the right to change the product described in this datasheet. All information con-

tained in this datasheet is subject to change without prior notice. Princeton Technology Corp. assumes no responsibility

for the use of any circuits shown in this datasheet.

Description

The FS8107E is a serial data input, phase-locked loop IC with programmable input and

reference frequency dividers. When combined with a VCO, the FS8107E becomes the

core of a very low power frequency synthesizer well-suited for mobile communication

applications such as paging systems. Compared to the FS8100, the FS8107E is housed

in a smaller package and also implements a separate pin for stand-by control.

Features

High maximum input operating frequency — 100 MHz at V_DD1= 1.0 V

Up to 22 MHz internal crystal oscillator reference frequency at V_DD1= 1.0 V

Extremely low current consumption (I_DD,totaltypically 0.4 mA at f_FIN= 90 MHz)

16-bit programmable input frequency divider (including a ÷ 32/33 prescaler) with

divide ratio range from 992 to 65535

13-bit programmable reference frequency divider (including a ÷ 8 prescaler) with

divide ratio range from 40 to 65528

Optional lock detector output

Charge pump output for passive low-pass filter

Quick-lock signal output for faster locking

Separate pin for stand-by control

TSSOP 16L package (0.65mm pitch)
