3G/HD/SD SDI Adaptive Cable Equalizer 'LMH0324'
The LMH0324 is a low power consumption, dual output, adaptive cable equalizer with long transmission distance. It performs equalization of SDI data transmitted over 75Ω coaxial cables. It operates over a wide data rate range from 125Mbps to 2.97Gbps. Equipped with an active sensing circuit, it provides robust performance and enhanced resistance to variations in input signal activation amplitude. Additionally, it offers low power consumption, enabling extended transmission distances for cables, and features power management functionality that further reduces power consumption when there is no input signal. With two differential serial data outputs, it provides flexibility for fan-out buffering. The output driver includes a programmable de-emphasis function to compensate for board wiring losses at the output. *For more details, please contact us.
