The LMX2305 contains a dual modulus prescaler which can select either a 64 65 or a 128 129 divide ratio at input frequencies of up to 550 MHz LMX2305 which employs the digital phase lock loop technique combined with a high quality reference oscillator and a loop filter provides the tuning voltage for the voltage controlled oscillator to generate a very stable low noise local oscillator signal Serial data is transferred into the LMX2305 via a three line MICROWIRETM interface (Data Enable Clock) Supply voltage can range from 2 65V to 5 5V The LMX2305 features very low current consumption typically 4 0 mA at 2 75V The LMX2305 is available in a TSSOP 20-pin surface mount plastic package
