LMX2335L
Description
The LMX2335L and LMX2336L are monolithic, integrated dual frequency synthesizers, including two high frequency prescalers, and are designed for applications requiring two RF phase-lock loops. They are fabricated using National’s 0.5µ ABi C V silicon Bi CMOS process.
The LMX2335L/36L contains two dual modulus prescalers. A 64/65 or a 128/129 prescaler can be selected for each RF synthesizer. A second reference divider chain is included in the IC for improved system noise. The LMX2335L/36L bined with a high quality reference oscillator, two loop filters, and two external voltage controlled oscillators generates very stable low noise RF local oscillator signals.
Serial data is transferred into the LMX2335L/36L via a three wire interface (Data, Enable, Clock). Supply voltage can range from 2.7V to 5.5V. The LMX2335L/36L feature very low current consumption; LMX2335L 4.0 m A at 5V, LMX2336L 5.5 m A at 5V. The LMX2335L is available in SO, TSSOP and CSP 16-pin surface mount plastic...
