Features
• Ten LVCMOS clock outputs: 
Five LVCMOS 125MHz Ethernet outputs
Three LVCMOS 25MHz /125MHz Ethernet outputs
One LVCMOS 24MHz USB output
One LVCMOS 25MHz REF output
• QREF output can be used to drive other clock drivers, saving a
crystal
• Selectable crystal or differential LVPECL input
• RMS Phase Jitter, 125MHz, integration range 12kHz - 20MHz:
0.60ps (typical)
• Cycle-to-Cycle jitter: 20ps (typical)
• Flexible voltage supply modes; supports legacy and future system
requirements, minimizes power consumption
Core voltage: VDD, VDD_XTAL, VDDA
