Texas Instruments LMH1218-A low power ultra high definition cable driver, a low power cable driver with integrated clock recovery. The relocker is used to drive serial video data compatible with SMPTE-SDI, SMPTE 2022-5 / 6, 10GbE Ethernet and DVB-ASI standards.
The driver supports speeds up to 11.88Gbps and provides Ultra HD video for 4K / 8K applications. The LMH1218 has 75ohm and 50ohm transmitter outputs, enabling multiple media options such as coaxial cable, fiber optics, and FR-4 PCB.
LMH1218 integrates 2 to 1 MUX on the input, you can choose between two video sources. Programmable equalizers compensate PC board losses to extend the signal range. With extensive clock and data recovery (CDR) circuitry, the on-chip clock recoverer can automatically detect and lock serial data. They can operate from 270Mbps to 11.88Gbps without the need for external reference clocks and loop filter components. This simplifies board design and reduces system costs.
Typical applications include UHDTV / 4K / 8K / HDTV / SDTV video, digital video routers / switches, digital video processing / editing, DVB-ASI and distribution amplifiers, and 10GbE for SMPTE 2022-5 / 6 systems.
