The LMX1501A and the LMX1511 are high performance frequency synthesizers with integrated prescalers designed for RF operation up to 1.1 GHz. They are fabricated using National's ABiC IV BiCMOS process.
The LMX1501A and the LMX1511 contain dual modulus prescalers which can select either a 64/65 or a 128/129 divide ratio at input frequencies of up to 1.1 GHz. Using a proprietary digital phase locked loop technique, the LMX1501A/11's linear phase detector characteristics can generate very stable, low noise local oscillator signals. Serial data is transferred into the LMX1501A and the LMX1511 via a three line MICROWIRETM interface (Data, Enable, Clock). Supply voltage can range from 2.7V to 5.5V.
The LMX1501A and the LMX1511 feature very low current consumption, typically 6 mA at 3V.
The LMX1501A is available in a JEDEC 16-pin surface mount plastic package. The LMX1511 is available in a TSSOP 20-pin surface mount plastic package.
