LMX1601 Datasheet (National Semiconductor) - Low Cost Dual Frequency Synthesizer

LMX1601, Low Cost Dual Frequency Synthesizer

The LMX1600/01/02 is part of a family of monolithic integrated dual frequency synthesizers designed to be used in a local oscillator subsystem for a radio transceiver.

It is fabricated using National’s 0.5u ABiC V silicon BiCMOS process.

The LMX1600/01/02 contains two dual modulus prescalers, four p
