HXT45411-3 - Block Diagram
Description
The HXT45411-3 is a quad-channel linear EML driver array, which is a member of Renesas' family of Optical Receiver Transmitter Array (ORTA) products. Combining the HXT45411-3 driver with an EML array or a group of discrete EMLs enables designs for compact linear transmitters for the next generation of 400G/800G optical transceivers.
The HXT45411-3 is a low-power, high-performance, quad-channel linear driver, designed for 4x112Gb/s PAM4 EML–based transceivers. The HXT45411-3 is a small form factor (SFF) packaged surface mount device (SMD) with differential inputs and single-ended outputs consisting of 4x56Gbaud broadband amplifier channels, each capable of driving a linear output voltage of 2.0VPP, suitable for 4λ 400G PAM-4 applications.
