Application Scenarios & Design Considerations

14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT

Alternative Part Number

  • DS3150TN --: Single-channel T1/E1/J1 line interface unit in the same 14-channel LIU class, pin-compatible function and widely available as a drop-in for Exar XRT83SH314 designs.
  • IDT82V2084 --: Quad T1/E1/J1 line interface unit offering equivalent framing and line-driver functionality with a different vendor and series, suitable for multi-channel telecom line-card designs.
  • BCM56314 --: Multi-channel T1/E1 line interface device with comparable channel density and telecom interface features, usable as a functional substitute when board-level rework is acceptable.
  • BCM5521 --: Multi-channel T1/E1 line interface device with similar feature set and packaging, suitable as a functional substitute when the XR part is unavailable.
  • DS3154 --: Quad T1/E1/J1 line interface unit with similar transceiver functionality and pin-compatible architecture, widely used as a drop-in alternative for multi-channel telecom line cards.
  • PM4354 --: Four-channel T1/E1 transceiver offering comparable line interface and framing support, suitable for replacing the XRT83SH314 in telecom access equipment.
  • IDT82V2054 --: Quad-channel T1/E1/J1 line interface unit with similar feature set and electrical characteristics, commonly cross-referenced for XRT multi-port LIU designs.
