AI Summary

DS3144 by Analog Devices: Telecom IC Framer, Line Interface Unit (LIU) 144-CSPBGA (13x13).

The DS3144N is the industrial-temperature grade version of the DS3144. It is a direct drop-in replacement that supports the exact same features and quad-channel capacity while expanding the operating temperature range from commercial to industrial.

  • Direct drop-in replacement with no PCB redesign or firmware modification required.
  • Exceeds the temperature range of the DS3144 (Industrial -40°C to +85°C vs Commercial 0°C to +70°C).
  • Identical quad-channel framing and register structures.
  • Also carries an obsolete lifecycle status; sourcing relies on legacy distributor stock or specialized broker channels.

The DS3143 is a same-family, same-package triple-channel sibling of the quad-channel DS3144. If your system architecture uses 3 or fewer of the available 4 channels, the DS3143 acts as a drop-in replacement on the identical PCB footprint.

  • Pin-compatible sibling on the exact same 144-pin CSBGA footprint.
  • Simplifies inventory if the target design uses 3 or fewer channels.
  • No firmware modifications needed for active channels (Framers 1-3).
  • Loses the 4th independent DS3/E3 framer channel.
  • Like the DS3144, this part is also obsolete and is best suited for legacy repair or lower-channel-count retrofits.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
