VCXO reference accuracy)

Zero delay operation

Input-to-output edge timing: <150 ps

14 outputs: configurable LVPECL, LVDS, HSTL, and LVCMOS

14 dedicated output dividers with jitter-free adjustable delay

Adjustable delay: 63 resolution steps of ½ period of VCO

output divider

Output-to-output skew: <50 ps

Duty cycle correction for odd divider settings

Automatic synchronization of all outputs on power-up

Absolute output jitter: <200 fs at 122.88 MHz
