HXT45110-3-DNU – 112Gb/s PAM4 EML Laser Driver IC (Bare Die) – Renesas

The Renesas HXT45110-3-DNU is an obsolete single-channel linear EML laser driver die for 112Gb/s PAM4 optical transceivers. Available as a hard-to-find part via RFQ at Pacific Component Xchange.

The Renesas HXT45110-3-DNU is a single-channel linear EML (Electro-absorption Modulated Laser) driver die, supplied in bare-die form for hybrid optical sub-assembly. A member of the Renesas ORTA (Optical Receiver Transmitter Array) product family, this high-performance driver is engineered for next-generation 112Gb/s PAM4 EML-based optical transceivers used in datacom and high-speed interconnect applications. The device features a differential input and single-ended output, delivering a 2.0Vpp linear output voltage suitable for transmission links up to 10km and for driving silicon photonic modulators.

This part carries the -DNU (Die, Non-packaged Unit) suffix and is shipped as an unpackaged integrated circuit die intended for chip-on-board or hybrid module assembly. Renesas has designated the HXT45110-3 as Obsolete, making it a hard-to-find component with little to no authorized-distributor stock remaining.
