LMX2330L - (LMX2330L - LMX2332L) PLLatinumTM Low Power Dual Frequency Synthesizer

General Description

The LMX233XL family of monolithic, integrated dual frequency synthesizers, including prescalers, is to be used as a local oscillator for RF and first IF of a dual conversion transceiver.

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

Key Features

  • very low current consumption; LMX2330L.
  • 5.0 mA at 3V, LMX2331L.
