FUNCTIONAL DESCRIPTION
The PDU138-series device is a 3-bit digitally programmable delay line.
The delay, TD
A
, from the input pin (IN) to the output pin (OUT) depends on
the address code (A2-A0) according to the following formula:
TD
A
= TD
0
+ T
INC
* A
where A is the address code, T
INC
is the incremental delay of the device,
and TD
0
is the inherent delay of the device. The incremental delay is
specified by the dash number of the device and can range from 0.5ns
through 50ns, inclusively. The enable pin (EN/) is held LOW during normal
operation. When this signal is brought HIGH, OUT is forced into the LOW
state. The address is not latched and must remain asserted during normal operation.
