HXT32400

The HXT32400 is a quad channel, low power, Direct Modulated Laser (DML) driver array for LR4 optical applications that supports data rates up to 28Gbps and optical reach up to 2Km. In conjunction with a DFB laser diode array or individual DFB laser diodes, the device handles the complete digital-to-optical conversion, including CML input with equalization, laser driver, drive control, and supervision.

Designed for direct DC-coupled die in TOSA applications with a small number of additional components for cost-effective and compact assemblies. Available in die form.
