PI6LC48P0201A

PI6LC48P0201A 2-Output LVPECL Networking Clock Generator Features ÎÎTwo differential LVPECL output pairs ÎÎSelectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock input ÎÎSupports the following output frequencies: 62.5MHz, 125MHz, 156.25MHz ÎÎRMS phase jitter @ 156.25MHz, using a 25MHz crystal (12kHz – 20MHz): 0.3ps (typical) ÎÎRMS phase jitter @ 156.25MHz, using a 25MHz crystal (12kHz – 20MHz): 0.5ps (max.) ÎÎFull 3.3V or 2.5V supply modes ÎÎIndustrial operating temperature ÎÎAvailable in lead-free package: 20-TQFN Description The PI6LC48P0201A is a 2-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 crystal, the most popular Ethernet frequencies can be generated based on the settings of 2 frequency select pins. The PI6LC48P0201A 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.
