DESCRIPTION
The SY10/100E196 are programmable delay chips (PDCs) designed primarily for very accurate differential ECL input edge placement applications.
The delay section consists of a chain of gates and a linear ramp delay adjustment 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 E196 with a digitally-selectable resolution of approximately 20ps. The required device delay is selected by the seven address inputs D[0:6], which are latched on-chip by a high signal on the latch enable (LEN) control. If the LEN signal is...
