The MC100EP196 is a programmable delay chip (PDC) designed primarily for clock deskewing and timing adjustment. It provides programmably variable delay of a differential ECL input signal. It has similar architecture to the EP195 with the added feature of further tuneability in delay using the FTUNE pin. The FTUNE input takes an analog voltage from V
to V
to fine tune the output delay from 0 to 60 ps.
