Overview
STW81101 Multi-band RF frequency synthesizer with integrated VCOs Features ■ Integer-N frequency synthesizer ■ Dual differential integrated VCOs with automatic center frequency calibration: – 3300 - 3900 MHz (direct output) – 3800 - 4400 MHz (direct output) – 1650 - 1950 MHz (internal divider by 2) – 1900 - 2200 MHz (internal divider by 2) – 825 - 975 MHz (internal divider by 4) – 950 - 1100 MHz (internal divider by 4) ■ Excellent integrated phase noise ■ Fast lock time: 150 µs ■ Dual modulus programmable prescaler (16/17 or 19/20) ■ 2 programmable counters to achieve a feedback division ratio from 256 to 65551 (prescaler 16/17) and from 361 to 77836 (prescaler 19/20).
