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 鈥?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,total

typically 0.4 mA at f

FIN

= 90 MHz)

16-bit programmable input frequency divider (including a

梅

32/33 prescaler) with

divide ratio range from 992 to 65535

13-bit programmable reference frequency divider (including a

梅

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)
