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
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.
Because the delay programmability of the E195 is
achieved by purely differential ECL gate delays, the
device will operate at frequencies of >1GHz, while
maintaining over 600mV of output swing.
The E195 thus offers very fine resolution, at very high
frequencies, selectable entirely from a digital input,
allowing for very accurate system clock timing.
An eighth latched input, D
7
, is provided for cascading
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.
