The DS21348GN from Analog Devices / Maxim Integrated is a versatile Line Interface Unit (LIU) designed for E1, T1, or J1 telecommunication applications. It supports both long-haul and short-haul trunks, offering internal software-selectable receive-side termination for 75Ω, 100Ω, and 120Ω impedances.
This device operates from a 3.3V power supply and features a crystal-less jitter attenuator that requires only a 2.048MHz master clock. It generates appropriate line build-outs for E1 and T1 signals, supports various encoding/decoding schemes like AMI, HDB3, and B8ZS, and provides programmable monitor modes. The DS21348GN includes loopback capabilities and PRBS pattern generation/detection.
Packaged in a compact 49-CSBGA (7x7mm) format, the DS21348GN is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C, making it suitable for demanding environments. The interface can be configured as 8-bit parallel or serial, with support for Muxed and Nonmuxed parallel buses compatible with Intel or Motorola systems.
The DS21348GN provides a complete E1, T1, or J1 Line Interface Unit (LIU).
It supports both long-haul and short-haul trunks.
The operating voltage is between 3.135V and 3.465V.
The operating temperature range is -40°C to 85°C.
The DS21348GN is supplied in a 49-CSBGA (7x7) package.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level (MSL) is 1 Unlimited.
