LMX2370 Datasheet (National Semiconductor) - Dual Frequency Synthesizer

LMX2370, Dual Frequency Synthesizer

The LMX237X family of monolithic, integrated dual frequency synthesizers, including prescalers, is designed to be used as a first and second local oscillator for dual mode or dual conversion transceivers.

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

The LMX237X contains two d
