The LMX2346/7 are high performance frequency synthesizers with an integrated 32/33 dual modulus prescaler. The LMX2346 is designed for RF operation up to 2.0 GHz. The LMX2347 is designed for RF operation up to 2.5 GHz. Using a proprietary digital phase locked loop technique, the LMX2346/7 generates very stable, low noise control signals for UHF and VHF voltage controlled oscillators. Serial data is transferred into the LMX2346/7 via a three-line MICROWIRE interface (DATA, LE, CLOCK). Supply voltage range is from 2.7V to 5.5V. The charge pump provides 4 mA output current.
