LMX2315-X数据手册TI中文资料规格书

描述 Description

General Description
The LMX2315 is a high performance frequency synthesizer with integrated prescalers designed for RF operation up to 1.2 GHz. They are fabricated using National's ABiC IV BiCMOS process.
A 64/65 or a 128/129 divide ratio can be selected for the LMX2315 RF synthesizer at input frequencies of up to 1.2 GHz. Using a proprietary digital phase locked loop technique, the LMX2315's linear phase detector characteristics can generate very stable, low noise signals for controlling a local oscillator.
Serial data is transferred into the LMX2315 via a three line MICROWIRE(TM) interface (Data Enable, Clock). Supply voltage can range from 2.7V to 5.5V. The LMX2315 features very low current consumption, typically 6 mA.
The LMX2315, is available in a SOIC 20-pin surface mount ceramic package.
