Product Summary
The LMX2322TMC 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 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 LMX2322TMC via a three-line MICROWIRETM interface (Data, LE, Clock). Supply voltage range is from 2.7 V to 3.9 V. The LMX2322TMC features very low current consumption, typically 3.5 mA at 3.75V. The charge pump provides 4mA output current. The LMX2322TMC is manufactured using the ABiC V BiCMOS process and is packaged in a 16 pin TSSOP and a 16 pin Chip Scale Package (CSP). The applications of the LMX2322TMC are: (1)Cellular telephone systems (GSM, NADC, CDMA, PDC, PHS); (2)Personal wireless communications (DCS-1800, DECT, CT-1+); (3)Wireless local area networks (WLANs); (4)Other wireless communication systems.
