12G UHD-SDI Dual Output Cable Driver "LMH1208"
The LMH1208 is a low-power 12G UHD-SDI dual output cable driver with an integrated reclocker. It supports SMPTE video up to 11.88Gbps and is compatible with UHD video for 4K/8K applications. The host side features an additional reclocked 100Ω driver output for monitoring and signal distribution. The programmable PCB input equalizer provides high-frequency boost and reduces inter-symbol interference (ISI) caused by PCB trace wiring. The built-in 75Ω termination and return loss compensation network on both cable driver outputs enable compliance with stringent SMPTE return loss requirements. Input signal detection determines the presence of valid signals at the cable driver input. These detection features can be used for alerts regarding system failures and to initiate power-saving mode, thereby reducing the power consumption of the cable driver. It offers selectable slew rates for a maximum data rate of 11.88Gbps. Additionally, output slew rate and amplitude can be controlled via pin, SPI, or SMBus. *For more details, please contact us.*
