CY2XP22 Crystal to LVPECL Clock Generator Crystal to LVPECL Clock Generator Features Functional Description One LVPECL output pair The CY2XP22 is a PLL (Phase Locked Loop) based high performance clock generator that uses an external reference Selectable frequency multiplication: 2.5 or 5 crystal. It is specifically targeted at FibreChannel and Gigabit Ethernet applications. It produces a selectable output frequency External crystal frequency: 25.0 MHz that is 2.5 or 5 times the crystal frequency. With a 25 MHz crystal, Output frequency: 62.5 MHz or 125 MHz the user can select either a 62.5 MHz or 125 MHz output. It uses Cypresss low noise VCO technology to achieve less than 1 ps Low RMS phase jitter at 125 MHz, using 25 MHz crystal typical RMS phase jitter. The CY2XP22 has a crystal oscillator (1.875 MHz to 20 MHz): 0.4 ps (typical) interface input and one LVPECL output pair. Phase noise at 125 MHz (typical): For a complete list of related documentation, click here.
