BBT3420 is a quad 2.488-3.1875Gbps/channel transceiver that supports full rate and half rate, with a maximum data rate of 12.75Gbps.
The BBT3420 is a quad 8‑bit/10‑bit parallel‑to‑serial and serial‑to‑parallel transceiver designed for high‑bandwidth interconnections such as line cards, backplanes, or optical modules. It offers four independent channels with configurable data rates, pre‑emphasis, and built‑in self‑test features.
The device is supplied in a 289‑pin 19 mm × 19 mm HSBGA package, operates from a single 1.8 V supply, and consumes about 250 mW per channel. It supports both XAUI and XGMII interfaces and includes extensive MDIO‑controlled configuration options.
