FUNCTIONAL DESCRIPTION
The PDU1032H-series device is a 5-bit digitally programmable delay line.
The delay, TD
A
, from the input pin (IN) to the output pin (OUT) depends
on the address code (A4-A0) according to the following formula:
TD
A
= TD
0
+ T

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 20ns, inclusively. The
enable pin (ENB) is held LOW during normal operation. When this signal is brought HIGH, OUT is forced
into a LOW state. The address is not latched and must remain asserted during normal operation.
