The LMX2324A is a high performance frequency synthesizer with integrated 32/33 dual modulus prescaler designed for RF operation up to 2.2 GHz. Using a proprietary digital phase locked loop technique, the LMX2324A's linear phase detector characteristics can generate very stable, low noise control signals for UHF and VHF voltage controlled oscillators. Serial data is transferred into the LMX2324A via a three-line MICROWIRETM interface (Data, LE, Clock). Supply voltage range is from 2.7V to 5.5V. The LMX2324A features very low current consumption, typically 3.5 mA at 3V. The charge pump provides 4 mA output current. The LMX2324A is manufactured using National's ABiC V BiCMOS process and is packaged in a 16-pin TSSOP and a 16-pin Chip Scale Package (CSP).
