112Gb/s Linear EML Driver

The HXT45110-4 is a single-channel linear EML driver die, which is a member of the Renesas family of optical receiver transmitter array (ORTA) products. In conjunction with an EML, a compact linear transmitter can be designed for the next generation of 100G and 200G/400G optical small form factor (SFF) transceivers.

The device is a low-power, high-performance, single channel linear driver die with differential input and single-ended output consisting of one 56 Gbaud broadband amplifier channel, which is designed for 112Gbps PAM4 EML based transceivers. This design enables it to drive a linear output voltage as low as 1.2Vpp, which is suitable for low power applications.
