Description
The FS8160 is a serial data input, fully programmable dual phase-locked loop IC for use
in the local oscillator subsystem of radio transceivers. When combined with external
VCOs, the FS8160 becomes the core of a very low power dual frequency synthesizer well-
suited for mobile communication applications. The FS8160 is pin-compatible with
National Semiconductorâs LMX1602 IC.
Features
 Supply voltage operating range: 2.7 to 3.6 V
 Maximum input frequency: 1.1 GHz/1.1 GHz (main/auxiliary)
 Low current consumption (IDD,total typically 5 mA at VDD,main = VDD,aux = 3.0 V and < 1
µA in power down mode)
 16-bit programmable input (both main and auxiliary) frequency dividers (including a
÷ 16/17 prescaler) with divide ratio range from 240 to 65535
 12-bit programmable reference (both main and auxiliary) frequency dividers with
divide ratio range from 2 to 4095
 Programmable charge pump output
 Digital-filtered lock detect output
 16 pin, plastic TSSOP (0.65 mm pitch)
