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,total
typically 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)
