PI6LC48P21

PI6LC48P21 Single Output LVPECL Clock Generator Features ÎÎSingle differential LVPECL output ÎÎSupports the following output frequencies: 125MHz or 133MHz ÎÎRMS phase jitter @ 125MHz, using a 25MHz crystal (12kHz – 20MHz): 0.3ps (typical) ÎÎFull 3.3V or 2.5V supply modes ÎÎCommercial and industrial ambient operating temperature ÎÎAvailable in lead-free package: 8-TSSOP Description The PI6LC48P21 is a single output LVPECL synthesizer optimized to generate Ethernet reference clock frequencies and is a member of Pericom’s HiFlex family of high performance clock solutions. Using a 25MHz or 26.6MHz crystal, it can generate 125MHz or 133MHz output frequencies. The PI6LC48P21 uses Pericom’s proprietary low phase noise PLL technology to achieve ultra low phase jitter, so it is ideal for Ethernet interface in all kind of systems.
