The PI6LC48P21 is a single output LVPECL synthesizer opti- mized to generate Ethernet reference clock frequencies and is a member of Diodes' 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 Diodes' 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.
