? 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
