The LMX2315/2320/2325"s are high performance frequency synthesizers with integrated prescalers designed for RF operation up to 2.5 GHz. They are fabricated using TI"s ABiC IV BiCMOS process.
●A 64/65 or a 128/129 divide ratio can be selected for the LMX2315 and LMX2320 RF synthesizer at input frequencies of up to 1.2 GHz and 2.0 GHz, while 32/33 and 64/65 divide ratios are available in the 2.5 GHz LMX2325. Using a proprietary digital phase locked loop technique, the LMX2315/2320/2325"s linear phase detector characteristics can generate very stable, low noise signals for controlling a local oscillator.
●Serial data is transferred into the LMX2320 and the LMX2325 via a three line MICROWIRE interface (Data, Enable, Clock). Supply voltage can range from 2.7V to 5.5V. The LMX2315, LMX2320 and the LMX2325 feature very low current consumption, typically 6 mA, 10 mA and 11 mA respectively.
●The LMX2315, LMX2320 and the LMX2325 are available in a TSSOP 20-pin surface mount plastic package.
