... Document #: 001-06385 Rev. *H 312.5 MHz LVPECL Clock Generator Functional Description The CY2XP31 is a PLL (Phase Locked Loop) based high performance clock generator optimized to generate 10 Gb Ethernet, SONET, and other high performance clock frequencies. It also produces an output frequency that is 12.5 times the crystal frequency. It uses Cypress’s low noise VCO ...

... F Termination for LVPECL Output The CY2XP31 implements its LVPECL driver with a current steering design. For proper operation, it requires a 50 ohm dc termination on each of the two output signals. For 3.3 V operation, this data sheet specifies output levels for termination to V –2.0 V. This same termination voltage can also be used ...
