... Document #: 001-15705 Rev. *G Crystal to LVPECL Clock Generator Functional Description The CY2XP24 is a PLL (phase locked loop) based high performance clock generator optimized to generate 10 Gb Ethernet, Fibre Channel, and other high performance clock frequencies. It produces an output frequency that is either 6.25 times or 7.5 times the crystal frequency. It uses Cypress’s low ...
