Description

The CF1228 is a ludicrously low additive jitter 2:8 LVPECL clock fanout and divider. It is capable of receiving CMOS, LVPECL, LVDS, CML and HCSL input levels, LVPECL output logic level translation and programmable frequency division. The CF1228 is programmed through external control pins and is enclosed in a 4mm x 4mm MLP package.

Recommended for new designs
