SDI reclocker with integrated eye monitor for broadcast video systems

Texas Instruments Inc. has rolled out what it declares as the industry's first serial digital interface (SDI) reclocker with an integrated eye monitor for examining the shape and health of incoming signal waveforms. The on-chip eye monitor provides real-time monitoring and diagnostics at the reclocker's input, allowing engineers to easily optimise their broadcast video system and speed time-to-market, noted the company.

The LMH0366 3Gb/s HD/SD reclocker consumes 50 per cent less power than the competition, while offering best-in-class jitter performance and signal integrity for digital video routers, distribution amplifiers and video test equipment, boasted the company.

The LMH0366 features an on-chip oscilloscope probe that enables designers to examine transmitted signals at any point in the system for faster time-to-market. End users of the equipment save time and repair costs through the eye monitor's remote diagnostics and system debug capabilities. It also delivers 100mW typical power consumption that enables system designers to pack in more channels and features into smaller frames.

The LMH0366 joins the LMH0376 reclocker, which offers the same features but adds an integrated 4:1 input multiplexer. Both devices retime serial digital video data conforming to the Society of Motion Picture and Television Engineers (SMPTE) 424M, SMPTE 292M and SMPTE 259M-C standards for transmitting high-resolution uncompressed video signals.

Engineers can develop a high-resolution video system solution by combining the LMH0366 or LMH0376 with the LMH0394 or LMH0395 3-Gbit/s adaptive cable equalisers, LMH0302 or LMH0307 3-Gbit/s cable drivers, SN65LVCP408 8x8 4.25-Gbit/s crosspoint switch, LMZ14203 3-A SIMPLE SWITCHER power module, LP5900 150-mA linear regulator and the TMS320DM8168 DaVinci video processor.

The SD3GDAIII evaluation module (EVM) is available to accelerate the development of systems using the LMH0366 and LMH0376 for a suggested retail price of $499. IBIS models for the LMH0366 and LMH0376 are also available to verify board signal integrity requirements.

The LMH0366 is available in a 4 x 4mm, 24-pin QFN package for a suggested retail price of $19.95 in 1,000-unit quantities. The LMH0376 is offered in a 7 x 7mm, 48-pin QFN package for a suggested retail price of $21.50 in 1,000-unit quantities.
