The LMH0318 is a 3 Gbps HD/SD SDI Reclocker with Integrated Cable Driver designed to drive serial video data compatible to SMPTE-SDI and DVB-ASI standards. The clock and data recovery circuit eliminates accumulated jitter and detects the incoming data rate without requiring an external reference clock. The integrated driver with 75 ohm and 50 ohm outputs enables multiple media options such as coax and FR4 PCB. The integrated 2-to-1 MUX on the input of the LMH0318 enables selection between two video sources, while the programmable equalizer compensates for the PC board loss to extend signal reach. With a wide range clockand- data recovery (CDR) circuit, the on-chip reclocker automatically detects and locks to serial data from 270 Mbps to 2.97 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 ST 424, 344, 292, and 259 standards. A non-disruptive eye monitor allows for real-time measurement of serial data to simplify system startup or field tuning.
