Description

Skyworks SKY72300-21 direct digital modulation fractional-N frequency synthesizer provides ultra-fine frequency resolution, fast switching speed, and low phase-noise performance. This synthesizer is a key building block for high-performance radio system designs that require low power and fine step size.

Features

• Spur-free operation

• 2.1 GHz maximum operating frequency

• 500 MHz maximum auxiliary synthesizer

• Ultra-fine step size, 100 Hz or less

• High internal reference frequency enables large loop bandwidth implementations

• Very fast switching speed (e.g., below 100 Ps)

• Phase noise to –91 dBc/Hz inside the loop filter bandwidth @ 1800 MHz

• Software programmable power-down modes

• High-speed serial interface up to 100 Mbps

• Three-wire programming

• Programmable division ratios on reference frequency

• Phase detectors with programmable gain to provide a programmable loop bandwidth

• Frequency power steering further enhances rapid acquisition time

• On-chip crystal oscillator

• Frequency adjust for temperature compensation

• Direct digital modulation

• 3 V operation

• 5 V output to loop filter
