DS21348 - 3.3V E1/T1/J1 Line Interface

DS21348 Description

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

DS21348 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 Opti

DS21348 Applications

* Throughout the data sheet, J1 is represented wherever T1 exists. Receive sensitivity adjusts automatically to the incoming signal and can be programmed for 0dB to 12dB or 0dB to 43dB for E1 applications and 0dB to 30dB or 0dB to 36dB for T1 applications. The device can generate the necessary G.703
