LMH1218RTWT

The LMH1218RTWT 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 11.88Gbps to enable Ultra High Definition Video for 4K/8K applications. 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 270Mbps to 11.88Gbps without the need for an external reference clock and loop filter component. 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).

• Locks to rates 11.88, 5.94, 2.97, 1.485 Gbps
• Reference-free operation with fast lock time covering all supported or selected data rates
• Integrated 2:1 mux input, 1:2 demux/fanout outputs
• Automatic slew rate based on input rate detect
• On-chip eye monitor
• Low 300mW Power consumption with automatic power down on loss Of input signal
• Programmable via SPI or SMBus interface
