The PI6LC48P04 is a 4-output LVPECL synthesizer optimized to generate Ethernet and Fibre Channel reference clock frequencies and is a member of Diodes' HiFlex family of high performance clock solutions. Using a 26.5625MHz or a 26.04166MHz crystal, the following frequencies can be generated based on the settings of 2 frequency select pins (N_SEL[1:0]): 212.5MHz, 159.375MHz, 106.25MHz, 53.125MHz, and 156.25MHz.
The PI6LC48P04 uses Diodes' proprietary low phase noise VCO technology and can achieve less than 1ps typical rms phase jitter, so it is ideal for Ethernet interface in all kind of systems.

Application information, Evaluation board, and Other technical documents
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.
