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 VDD1
= 1.0 V
Up to 22 MHz internal crystal oscillator reference frequency at
VDD1 = 1.0 V
Extremely low current consumption (IDD,total
typically 0.4 mA at fFIN = 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
