LMH1218 Low Power Ultra HD Cable Driver

Texas Instruments LMH1218 Low Power Ultra HD Cable Driver is a low-power cable driver with integrated reclocker. The relocker is used to drive serial video data compatible to SMPTE-SDI, SMPTE 2022-5/6, 10GbE Ethernet, and DVB-ASI standards. This driver supports up to 11.88Gbps to enable Ultra High Definition Video for 4K/8K applications. With 75Ω and 50Ω transmitter outputs, the LMH1218 from Texas Instruments enables multiple media options such as coax, fiber, and FR-4 PCB. The integrated 2-to-1 MUX on the input of the LMH1218 enables selection between two video sources. The programmable equalizer compensates for the PC board loss to extend signal reach. With a wide range of Clock-and-Data Recovery (CDR) circuit, the on-chip re-clocker automatically detects and locks to serial data. These can be from 270Mbps to 11.88Gbps without the need for an external reference clock and loop filter component. This simplifies board design and lowers system costs.
