1. Duty cycle skew guaranteed only for differential operation measured from the cross point of the input to the cross point of the output.
2. This setup time defines the amount of time prior to the input signal the delay tap of the device must be set.
3. This setup time is the minimum time that EN must be asserted prior to the next transition of IN/IN to prevent an output response greater than
±75
mV to that IN/IN transition.
4. This hold time is the minimum time that EN must remain asserted after a negative going IN or positive going IN to prevent an output response
greater than
±75
mV to that IN/IN transition.
5. This release time is the minimum time that EN must be deasserted prior to the next IN/IN transition to ensure an output response that meets
the specified IN to Q propagation delay and transition times.
6. Specification limits represent the amount of delay added with the assertion of each individual delay control pin. The various combinations of
asserted delay control inputs will typically realize D0 resolution steps across the specified programmable range.
7. The linearity specification guarantees to which delay control input the programmable steps will be monotonic (i.e. increasing delay steps for
increasing binary counts on the control inputs Dn). Typically the device will be monotonic to the D0 input, however under worst case conditions
and process variation, delays could decrease slightly with increasing binary counts when the D0 input is the LSB. With the D1 input as the LSB
the device is guaranteed to be monotonic over all specified environmental conditions and process variation.
8. The jitter of the device is less than what can be measured without resorting to very tedious and specialized measurement techniques.

Figure 1. Cascading Interconnect Architecture
Cascading Multiple E195’s
To increase the programmable range of the E195 internal
cascade circuitry has been included. This circuitry allows for
the cascading of multiple E195’s without the need for any
external gating. Furthermore this capability requires only one
more address line per added E195. Obviously cascading
multiple PDC’s will result in a larger programmable range
however this increase is at the expense of a longer minimum
delay.
Figure 1 illustrates the interconnect scheme for cascading
two E195’s. As can be seen, this scheme can easily be
expanded for larger E195 chains. The D7 input of the E195 is
the cascade control pin. With the interconnect scheme of
Figure 1 when D7 is asserted it signals the need for a larger
programmable range than is achievable with a single device.
An expansion of the latch section of the block diagram is
pictured below. Use of this diagram will simplify the
explanation of how the cascade circuitry works. When D7 of
chip #1 above is low the cascade output will also be low while
the cascade bar output will be a logical high. In this condition
the SET MIN pin of chip #2 will be asserted and thus all of the
latches of chip #2 will be reset and the device will be set at its
minimum delay. Since the RESET and SET inputs of the
latches are overriding any changes on the A0–A6 address bus
will not affect the operation of chip #2.
TO SELECT MULTIPLEXERS
Chip #1 on the other hand will have both SET MIN and SET
MAX de-asserted so that its delay will be controlled entirely by
the address bus A0–A6. If the delay needed is greater than
can be achieved with 31.75 gate delays (1111111 on the
A0–A6 address bus) D7 will be asserted to signal the need to
cascade the delay to the next E195 device. When D7 is
asserted the SET MIN pin of chip #2 will be de-asserted and
the delay will be controlled by the A0–A6 address bus. Chip #1
on the other hand will have its SET MAX pin asserted resulting
in the device delay to be independent of the A0–A6 address
bus.
When the SET MAX pin of chip #1 is asserted the D0 and D1
latches will be reset while the rest of the latches will be set. In
addition, to maintain monotonicity an additional gate delay is
selected in the cascade circuitry. As a result when D7 of chip
#1 is asserted the delay increases from 31.75 gates to 32
gates. A 32 gate delay is the maximum delay setting for the
E195.
To expand this cascading scheme to more devices one
simply needs to connect the D7 input and CASCADE outputs
of the current most significant E195 to the new most significant
E195 in the same manner as pictured in Figure 1. The only
addition to the logic is the increase of one line to the address
bus for cascade control of the second PDC.
