3.3V ECL Programmable
Delay Chip
The MC10/100EP195 is a Programmable Delay Chip (PDC)
designed primarily for clock deskewing and timing adjustment. It
provides variable delay of a differential NECL/PECL input transition.
http://onsemi.com
The delay section consists of a programmable matrix of gates and
multiplexers as shown in the logic diagram, Figure 3. The delay
increment of the EP195 has a digitally selectable resolution of about
MARKING

10 ps and a net range of up to 10.2 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
MCXXX
real time delay values by D[9:0]. A LOW to HIGH transition on LEN
EP195
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
CASE 873A
Table 6 and Figure 4.

Because the EP195 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

Figure 5. AC Reference Measurement
Cascading Multiple EP195s
To increase the programmable range of the EP195,
internal cascade circuitry has been included. This circuitry
allows for the cascading of multiple EP195s without the
need for any external gating. Furthermore, this capability
requires only one more address line per added E195.
Obviously, cascading multiple programmable delay chips
will result in a larger programmable range: however, this
increase is at the expense of a longer minimum delay.
Figure 6 illustrates the interconnect scheme for cascading
two EP195s. As can be seen, this scheme can easily be
expanded for larger EP195 chains. The D10 input of the
EP195 is the CASCADE control pin. With the interconnect
scheme of Figure 6 when D10 is asserted, it signals the need
for a larger programmable range than is achievable with a
single device and switches output pin CASCADE HIGH and
pin CASCADE LOW. The A11 address can be added to
generate a cascade output for the next EP195. For a 2−device
configuration, A11 is not required.

(1111111111 on the A0—A9 address bus) D10 will be
asserted to signal the need to cascade the delay to the next
EP195 device. When D10 is asserted, the SET MIN pin of
chip #2 will be deasserted and SET MAX pin asserted
resulting in the device delay to be the maximum delay.
Table 13 shows the delay time of two EP195 chips in
cascade.
To expand this cascading scheme to more devices, one
simply needs to connect the D10 pin from the next chip to
the address bus and CASCADE outputs to the next chip in
the same manner as pictured in Figure 6. The only addition
to the logic is the increase of one line to the address bus for
cascade control of the second programmable delay chip.
An expansion of the latch section of the block diagram is
pictured in Figure 7. Use of this diagram will simplify the
explanation of how the cascade circuitry works. When D10
of chip #1 in Figure 6 is LOW this device’s
CASCADE output will also be low while the CASCADE
output will be high. In this condition the SET MIN pin of
chip #2 will be asserted HIGH and thus all of the latches of
chip #2 will be reset and the device will be set at its minimum
delay.
Chip #1, on the other hand, will have both SET MIN and
SET MAX deasserted so that its delay will be controlled
entirely by the address bus A0—A9. If the delay needed is
greater than can be achieved with 1023 gate delays

be sent through each EP195 as shown in Figure 8. One signal
channel can be used as reference and the other EP195s can be
used to adjust the delay to eliminate the timing skews. Nearly
any high−speed system can be fine−tuned (as small as 10 ps)
to reduce the skew to extremely tight tolerances.
The most practical application for EP195 is in multiple
channel delay matching. Slight differences in impedance and
cable length can create large timing skews within a high−speed
system. To deskew multiple signal channels, each channel can

Measure Unknown High Speed Device Delays
If the programmed delay through the second EP195 is too
long, the flip−flop output will be at logic high. On the other
hand, if the programmed delay through the second EP195 is
too short, the flip−flop output will be at a logic low. If the
programmed delay is correctly fine−tuned in the second
EP195, the flip−flop will bounce between logic high and logic
low. The digital code in the second EP195 can be directly
correlated into an accurate device delay.
EP195s provide a possible solution to measure the
unknown delay of a device with a high degree of precision.
By combining two EP195s and EP31 as shown in Figure 9,
the delay can be measured. The first EP195 can be set to
SETMIN and its output is used to drive the unknown delay
device, which in turn drives the input of a D flip−flop of
EP31. The second EP195 is triggered along with the first
EP195 and its output provides a clock signal for EP31.
The programmed delay of the second EP195 is varied to
detect the output edge from the unknown delay device.
