FEATURES
FUNCTIONAL DESCRIPTION
The PDU53-series device is a 3-bit digitally programmable delay line. The
delay, TD
address code (A2-A0) according to the following formula:
where A is the address code, T
and TD
specified by the dash number of the device and can range from 100ps through 3000ps, inclusively. The
address is not latched and must remain asserted during normal operation.

... Input & outputs fully 100K-ECL interfaced & buffered • Available in 16-pin DIP (600 mil) socket or SMD FUNCTIONAL DESCRIPTION The PDU53-series device is a 3-bit digitally programmable delay line. The delay from the input pin (IN) to the output pin (OUT) depends on the A address code (A2-A0) according to the following formula: ...

... PDU53 ADDRESS UPDATE The PDU53 is a memory device. As such, special precautions must be taken when changing the delay address in order to prevent spurious output signals. The timing restrictions are shown in Figure 1. After the last signal edge to be delayed has appeared on the OUT pin, a minimum time required before the address lines can change ...
