Product Summary

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 wellsuited for mobile communication applications. The FS8160 is pin-compatible with National Semiconductors LMX1602 IC.
