Description

The LMX2312U are high performance frequency syn-thesizers. The LMX2310/1/2U use a selectable, dual modu-lus 32/33 and 16/17 prescaler. The LMX2313U uses a se-lectable, dual modulus 16/17 and 8/9 prescaler. The device,when combined with a high quality reference oscillator and avoltage controlled oscillator, generates very stable, low noiselocal oscillator signals for up and down conversion in wire-less communication devices.

Serial data is transferred into LMX2312U via a three-wire interface (Data, Enable, Clock) that can be directlyinterfaced with low voltage baseband processors. Supplyvoltage can range from 2.7V to 5.5V. LMX2310U featuresvery low current consumption, typically 2.3 mA at 3.0V.

The LMX2312U are manufactured using National's0.5µ ABiC V silicon BiCMOS process and is available in20-pin CSP packages.
