Decreased-pitch TIA helps 56-GBd PAM4 operation

Semtech has introduced manufacturing availability of its GN1814 quad-channel transimpedance amplifer (TIA) to be used in 400G and 800G information facilities. The 56-GBd PAM 4 amplifier boasts a diminished I/O channel pitch of 500 µm and is well-suited for very high-density, single-mode fiber functions. It additionally presents low input-referred noise, excessive acquire, and output-swing degree detection.

“The manufacturing availability of the FiberEdge GN1814 permits qualification testing of the most recent optical transceiver know-how in information facilities by our clients and system distributors who demand distinctive high quality and efficiency,” stated Nicola Bramante, senior product line supervisor for Semtech’s Sign Integrity Merchandise Group. “The diminished pitch of the brand new FiberEdge GN1814, mixed with all the most recent options from Semtech’s FiberEdge PAM4 TIAs and rigorous high quality methodologies, permits the speedy deployment of subsequent technology 100G/lane OSFP and QSFP-DD optical transceivers.”

The GN1814 linear transimpedance amplifier is accessible as wire-bondable naked die. It’s supposed for 400GBASE-DR4, FR4, LR4, and 800GBASE-DR8 PAM4 optical transceivers; chip-on-board optical assemblies; and silicon photonics. Log in or register for mySemtech to entry product documentation.
