PHC31028

8-channel Arbitrary Frequency, Arbitrary Output Clock Generator

The PHC31028 is an 8-channel low-jitter clock generator with arbitrary frequency and output format, suitable for high-performance consumer, networking, industrial, computing, and data communication applications. It generates frequency signals from a reference clock and can drive 8 clock outputs in a highly flexible manner from 4 FODs. Each channel supports output levels including LVCMOS, LVDS, HCSL, LP-HCSL, LVPECL, and CML.
