Description
The HXT44100 is a single channel, low power, Linear PAM4 Direct Modulated Laser (DML) driver for LR optical applications that supports signaling rates up to 28GBaud or 56Gbps PAM4. In conjunction with an individual DFB laser diode, the device handles the complete digital-to-optical conversion, including CML input with equalization, laser driver, drive control, and supervision. The HXT44100 also integrates a number of functions required for Automatic Power Control (APC), as well as internal and module temperature measurements and reporting. Using the included RSSI input, the module receive optical power can also be measured and reported. 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.
