DS21348 - 3.3V E1/T1/J1 Line Interface

Datasheet Summary

Description

The DS21348 is a complete selectable E1 or T1 line interface unit (LIU) for short-haul and long-haul applications.

Throughout the data sheet, J1 is represented wherever T1 exists.

Features

  • Complete E1, T1, or J1 Line Interface Unit (LIU) Supports Both Long-Haul And Short-Haul Trunks Internal Software-Selectable Receive-Side Termination for 75Ω/100Ω/120Ω 3.3V Power Supply 32-Bit or 128-Bit Crystal-Less Jitter Attenuator Requires Only a 2.048MHz Master Clock for Both E1 and T1 with Option to Use 1.544MHz for T1 Generates the Appropriate Line Build-Outs, with and without Return loss, for E1 and DSX-1 and CSU Line Build-Outs for T1 AMI, HDB3, and B8ZS, Encoding/Decoding 16.384MHz, 8.1.
