The LMH1218 is a low-power cable driver with integrated reclocker to drive serial video data compatible to SMPTE-SDI, SMPTE 2022-5/6, 10GbE Ethernet, and DVB-ASI standards. The LMH1218 supports up to 11.88 Gbps to enable Ultra High Definition Video for 4K/8K applications. With 75-Ω and 50-Ω transmitter outputs, the LMH1218 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, while the programmable equalizer compensates for the PC board loss to extend signal reach. With a wide range clock-and-data recovery (CDR) circuit, the on-chip reclocker automatically detects and locks to serial data from 270 Mbps to 11.88 Gbps without the need for an external reference clock and loop filter component, thereby simplifying board design and lowering system cost. The reclocked serial data can be routed to either the 75-Ω or 50-Ω transmitter output, or both simultaneously (1-to-2 fanout mode). The output voltage swing is compatible to SFF-8431 (SFP+), ST2082/1 (Proposed), SMPTE 424M, 344M, 292M, and 259M standards. A non-disruptive eye monitor allows for real-time measurement of serial data to simplify system startup or field tuning. The LMH1218 can be programmed using SPI or SMBus Interface.
