LMX2330A Datasheet | National Semiconductor

Description The LMX233x A family of monolithic, integrated dual frequency synthesizers, including prescalers, is to be used as a local oscillator for RF and first IF of a dual conversion transceiver. It is fabricated using National’s ABi C IV silicon Bi CMOS process. The LMX233x A contains dual modulus prescalers. A 64/65 or a 128/129 prescaler (32/33 or 64/65 in the 2.5 GHz LMX2330A) can be selected for the RF synthesizer and a 8/9 or a 16/17 prescaler can be selected for the IF synthesizer. LMX233XA, which employs a digital phase locked loop technique, bined with a high quality reference oscillator and loop filters, provides the tuning voltages for voltage controlled oscillators to generate very...
