Description
LMX2335L/LMX2336L PLLatinum Low Power Dual Frequency Synthesizer for RF Personal Communications PRELIMINARY June 1999 LMX2335L/LMX2336L PLLatinum™ L.
The LMX2335L and LMX2336L are monolithic, integrated dual frequency synthesizers, including two high frequency prescalers, and are designed for applic.
Features
* n Ultra low current consumption n 2.7V to 5.5V operation n Selectable synchronous and asynchronous powerdown
mode: ICC = 1 µA (typ) n Dual modulus prescaler: 64/65 or 128/129 n Selectable charge pump TRI-STATE® mode n Selectable charge pump current levels n Selectable Fastlock™ mode n Upgrade and co
Applications
* requiring two RF phase-lock loops. They are fabricated using National’s 0.5µ ABiC V silicon BiCMOS 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 improv
