The PI6LC48L0201 is a 2-output LVDS 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 PI6LC48L0201 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.

LVPECL is Low Voltage Positive (supply) Emitter Couple Logic. Its voltage level is around 2V+/-400mV and the most use termination is 150 ohm pull-down at output pin and AC or DC coupling to an equivalent 100 ohm across pair at RX ASIC side. Check ASIC datasheet to prevent double termination.
