The DS2172 Bit Error Rate Tester (BERT) is a software programmable test pattern generator, receiver, and analyzer capable of meeting the most stringent error performance requirements of digital transmission facilities. Two categories of test pattern generation (Pseudo-random and Repetitive) conform to CCITT/ITU O.151, O.152, O.153, and O.161 standards. The DS2172 operates at clock rates ranging from DC to 52 MHz. This wide range of operating frequency allows the DS2172 to be used in existing and future test equipment, transmission facilities, switching equipment, multiplexers, DACs, Routers, Bridges, CSUs, DSUs, and CPE equipment. The DS2172 user-programmable pattern registers provide
The DS2172 is a software‑programmable bit error rate tester that generates and detects digital bit patterns for analyzing, evaluating and troubleshooting communication systems. It operates from DC to 52 MHz, supports programmable polynomial lengths, user‑defined patterns, and provides a 32‑bit error counter and an 8‑bit parallel control port.
The manual details the functional blocks, pin assignments, register map, and programming procedures. It covers pattern generation, synchronization, BER calculation, error insertion, power‑up sequence, and electrical characteristics, allowing users to configure the device for a wide range of test applications.
| Operating frequency | DC to 52 MHz |
|---|---|
| Error counter size | 32‑bit |
| Parallel control interface | 8‑bit |
| Supply voltage | 5.0 V (VDD) |

The DS2172 can operate up to 52 MHz.
It uses a 32‑bit error count register.
Errors are inserted via the Error Insertion Register (EIR).
The device needs a 5.0 V positive supply (VDD) and ground (VSS).
