LVPECL Clock Buffers

Our LVPECL clock buffers are low jitter non-PLL based fanout buffers delivering best-in-class performance, minimal cross-talk and superior supply noise rejection. Devices are available in industrial and automotive grade2 temperature ranges. With additive jitter as low as 50-fs RMS, our LVPECL buffers deliver up to 10 output clocks from DC to 1250 MHZ.

Outputs
Up to 10
Operating frequency
DC - 1.25 GHz
