• Jitter as low as 64 fs RMS maximum (10kHz to 20MHz)
• PLL core consists of fractional-feedback Analog PLL (APLL)
○ Operates from a 25MHz to 80MHz crystal or XO
○ APLL frequency independent of input / crystal frequency
○ Operates as a frequency synthesizer or Digitally
Controlled Oscillator (DCO)
○ DCO has tuning granularity of < 1ppb
• Programmable status output
• 4 differential / 8 LVCMOS outputs
○ Any frequency from 10MHz to 1GHz (180MHz for LVCMOS)
○ Programmable output buffer supports HCSL
(DC-coupled), LVDS/LVPECL/CML (AC-coupled)
or two LVCMOS
○ Differential output swing is selectable: 400mV to 800mV
○ Output Enable input with programmable effect
