The HXT45111-4 is a single channel linear EML driver, which is a member of the Renesas family of Optical Receiver Transmitter Array (ORTA) products. Together with an EML, a compact linear transmitter can be designed for the next generation of 100G and 200G/400G optical transceivers.

The HXT45111-4 is a low-power, high-performance, single channel linear driver, designed for 112Gbps PAM4 EML–based transceivers. The device is a small form factor (SFF) packaged surface mount device (SMD) with differential inputs and single-ended outputs consisting of one 56Gbaud broadband amplifier channel. This design enables it to drive a linear output voltage of 2.0Vpp, which is suitable for 112G PAM-4 applications.
