Datasheet
MC100EP196A
3.3 V ECL Programmable
Delay Chip With FTUNE
primarily for clock deskewing and timing adjustment. It provides
variable delay of a differential NECL/PECL input transition. It has
similar architecture to the EP195 with the added feature of further
tunability in delay using the FTUNE pin. The FTUNE input takes an
analog voltage from V
0 to 60 ps.
multiplexers as shown in the logic diagram, Figure 2. The delay
increment of the EP196A has a digitally selectable resolution of about
10 ps and a net range of up to 10.4 ns. The required delay is selected by
the 10 data select inputs D[9:0] values and controlled by the LEN
(pin 10). A LOW level on LEN allows a transparent LOAD mode of
real time delay values by D[9:0]. A LOW to HIGH transition on LEN
will LOCK and HOLD current values present against any subsequent
changes in D[10:0]. The approximate delay values for varying tap
numbers correlating to D0 (LSB) through D9 (MSB) are shown in
Table 6 and Figure 3.
signals. Because the MC100EP196A is designed using a chain of
multiplexers it has a fixed minimum delay of 2.2 ns. An additional pin
D10 is provided for controlling Pins 14 and 15, CASCADE and
CASCADE, also latched by LEN, in cascading multiple PDCs for
increased programmable range. The cascade logic allows full control of
multiple PDCs. Switching devices from all “1” states on D[0:9] with
SETMAX LOW to all “0” states on D[0:9] with SETMAX HIGH will
increase the delay equivalent to “D0”, the minimum increment.
