The 853S01 is a high performance 2:1 Differential-to-LVPECL Multiplexer. The 853S01 can also perform differential translation because the differential inputs accept LVPECL, LVDS and CML levels. The 853S01 is packaged in a small 3mm x 3mm 16 VFQFN package, making it ideal for use on space constrained boards.
One LVPECL output pair
Two selectable differential LVPECL clock inputs
PCLKx, nPCLKx pairs can accept the following differential input levels: LVPECL, LVDS, CML
Translates LVCMOS/LVTTL input signals to LVPECL levels by using a resistor bias network on nPCLKx, nPCLKx
