This document describes the PDU-1016H series of Digitally Programmable Delay Units manufactured by Data Delay Devices. These units feature a 4-bit ECL programmable delay line with low propagation delay and buffered inputs and outputs.
The datasheet provides key specifications such as programmed delay tolerance, inherent delay, and power dissipation. It includes a comprehensive truth table listing various part numbers (e.g., PDU-1016H-5 through PDU-1016H-100) with their corresponding incremental delays and total programmed delays.
| Delay variation | Monotonic in one direction. |
|---|---|
| Programmed delay tolerance | -6% or 1 ns whichever is greater |
| Inherent delay (Too) | 5.5 ns + 1 ns for PDU-1016H-1 thru -5 |
| Propagation delay Address to output | 3.6 ns typ. |
| Power dissipation | 615 mw typ. |
| Supply voltage | -5 Vdc + 5% |
| Operating Temperature | 0-70°C |
The programmed delay tolerance is either 6% or 1 ns, whichever value is greater.
The typical address-to-output delay is 3.6 ns, while the enable-to-output delay is 1.7 ns.
