Note 1: Absolute Maximum Ratings indicate limits beyond which damage the device may occur. Operating Ratings indicate conditions for which device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed.

The LMX2314 and the LMX2315 are high performance frequency synthesizers with integrated prescalers designed for RF operation up to 1.2 GHz. They are fabricated using National's ABiC IV BiCMOS process. The LMX2314 and the LMX2315 contain dual modulus prescalers which can select either a 64/65 or a 128/129 divide ratio at input frequencies of up to 1.2 GHz.

Using a proprietary digital phase locked loop technique, the LMX2314/15's linear phase detector characteristics can generate very stable, low noise local oscillator signals. Serial data is transferred into the LMX2314 and the LMX2315 via a three line MICROWIRETM interface (Data, Enable, Clock). Supply voltage can range from 2.7V to 5.5V. The LMX2314 and the LMX2315 feature very low current consumption, typically 6 mA at 3V. The LMX2314 is available in a JEDEC 16-pin surface mount plastic package. The LMX2315 is available in a TSSOP
