PI6LC4833 FAQs

What is HiFlex® clock IC?

PI6LCxxxx is Pericom's newly developed high frequency, very low jitter clock generator family, which use high Q silicon VCO to dramatically reduce traditional PLL clock jitter. They are especially good for Telecom, Datacom, and Ethernet for phase jitter <=1 ps designs.  HiFlex Clock FInder tool

What is LVPECL clock and its termination?

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.
