DELAY CHIP

(PDCs) designed primarily for clock de-skewing and timing

adjustment. They provide variable delay of a differential

ECL input transition.

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

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 either LOW or left floating, then the

latch is transparent.

achieved by purely differential ECL gate delays, the

device will operate at frequencies of >1GHz, while

maintaining over 600mV of output swing.

frequencies, selectable entirely from a digital input,

allowing for very accurate system clock timing.

multiple PDCs for increased programmable range. The

cascade logic allows full control of multiple PDCs, at the

expense of only a single added line to the data bus for

each additional PDC, without the need for any external

gating.

DESCRIPTION

The SY10/100E195 are programmable delay chips

The delay section consists of a chain of gates

Because the delay programmability of the E195 is

The E195 thus offers very fine resolution, at very high
