Features RF operation up to 2.0 GHz 2.7V to 5.5V operation Low current consumption: ICC = 3.5 mA (typ) at VCC = 3.0V Dual modulus prescaler: 32/33 Internal balanced, low leakage charge pump Description The LMX2324 is a high performance frequency synthesizer with integrated 32/33 dual modulus prescaler designed for RF operation up to 2.0 GHz. Using a proprietary digital phase locked loop technique, the LMX2324'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 LMX2324 via a three-line MICROWIRE ™ interface (Data, LE, Clock). Supply voltage range is from 2.7V to 5.5V. The LMX2324 features very low current consumption, typically 3.5 mA at 3V. The charge pump provides 4 mA output current. The LMX2324 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).
