SKY74038-21 2.6 GHz/800 MHz Dual Fractional-N/lnteger-N Frequency Synthesizer

SKYWORKS SKY74038 is a complete, low-power 2.6 GHz/800 MHz dual frequency synthesizer. The device provides both Radio Frequency (RF) channels and Intermediate Frequency (IF) channels. Fractional-N operation offers low phase noise, fast settling time, and low spurious tones for RF channels. A standard integer-N division is used for IF channels. The three-wire serial interface provides programmable control of the frequency synthesizer to support dual-conversion transceivers.
