Part Details:

LMX2323 October 2000 LMX2323 PLLatinum PLLatinumTM 2.0 GHz Frequency Synthesizer for RFPersonal Communications General Description Features The LMX2323 is a high performance frequency synthesizer 2.0 n RF operation up to 2.0 GHz with integrated 32/33 dual modulus prescaler designed for n 2.7V to 5.5V operation RF operation up to 2.0 GHz. Using a proprietary digital n Low current consumption: Icc = 3.5mA (typ) at GHz phase locked loop technique, the LMX2323 s linear phase Vcc=3.0V detector characteristics can generate very stable, low noise n Digital Lock Detect control signals for UHF and VHF voltage controlled oscilla- n Dual modulus prescaler: 32/33 tors. Frequency n Internal balanced, low leakage charge pump Serial data is transferred into the LMX2323 via a three-lineMICROWIRETM interface (Data, LE, Clock). Supply voltage Applications range is from 2.7V to 5.5V. The LMX2323 features very lowcurent consumption, typically 3.5mA at 3V. The charge pump n Cellular telephone systems (GSM, NADC, CDMA, PDC, provides 4 mA output current. PHS) The LMX2323 is manufactured using National s ABiC V n Personal wireless communications (DCS-1800, DECT, BiCMOS process and is packaged in a 16-pin TSSOP. CT-1+) Synthesizer n Wireless local area networks (WLANs) n DCS/PCS infrastructure equipment n Other wireless communication systems Functional Block Diagram for RF Personal Communications DS101362-1 TRI-STATE® is a registered trademark of National Semiconductor Corporation.MICROWIRETM and PLLatinumTM are trademarks of National Semiconductor Corporation. © 2000 National Semiconductor Corporation DS101362 Connection Diagram LMX2323 DS101362-2 Top View Order Number LMX2323TM, LMX2323TMX See NS Package Number MTC16
