Resources for HXT44120
Description
The HXT44120 is a single channel, low power, Linear PAM4 Directly-Modulated Laser (DML) driver for LR applications. It supports signaling rates up to 28GBuad or 56Gbps in PAM4 modulation. In conjunction with an individual DML, the HXT44120 handles the complete electrical-to-optical conversion, including CML input with equalization, laser bias and modulations, laser power control and supervision.
The HXT44120 also integrates a number of functions required for Automatic Power Control (APC), as well as internal and module temperature measurements and reporting. With an additional RSSI input, one can directly measure the module receive optical power and report it.
HXT44120 is designed as a directly DC-coupled die used in a TOSA application. Thus, one can reduce the number of discrete components for better RF performance, cost-effective and compact assemblies.
