EdgeВ® The SY10/100E195 are programmable delay chips
(PDCs) designed primarily for clock de-skewing and timing
adjustment. They provide variable delay of a differential
ECL input transition.
The delay section consists of a chain of gates
organized as shown in the logic diagram. The first two
delay elements feature gates that have been modified to
have delays 1.25 and 1.5 times the basic gate delay of
approximately 80ps. These two elements provide the
E195 with a digitally-selectable resolution of …
