Product details

Transceiver for E1, J1, T1 line cards

The DS2155GNB is a single-chip transceiver from Analog Devices that handles, J1, and T1 framing with integrated HDLC controller — one part covers the three common PCM line rates, so a single BOM line can serve multi-protocol line cards.

BGA package and field-swap reality

The DS2155GNB comes in a 100-CSBGA (10x10) package — a 10 mm square BGA.

Active lifecycle — no obsolescence watch

For the sourcing desk, that means no last-time-buy scramble; you can plan multi-year production without a forced redesign. RoHS non-compliant — verify your assembly house can handle the tin-lead finish if your process is RoHS-exempt (military, aerospace, some industrial).

Sourcing posture and RFQ

No official second-source or pin-compatible alternative listed — the DS2155GNB is the sole member of this specific order code.

Frequently asked questions

Can DS2155GNB be used for T1 or J1 interfaces?

Yes — the DS2155GNB supports, J1, and T1 framing with HDLC, so it covers all three common PCM line rates in one chip. No external framer needed.

Is the DS2155GNB obsolete?

No successor has been announced.

What is the DS2155GNB used for?

It is a single-chip transceiver for, J1, and T1 telecom interfaces — typically found on line cards in PBX, multiplexer, and access equipment where HDLC framing is required.
