Texas Instruments has introduced an SDI (serial digital interface) 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 optimize their broadcast video system and speed time-to-market. The LMH0366 3-Gbps HD/SD reclocker consumes 50% 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.
Key features and benefits of the LMH0366
- Integrated eye monitor: On-chip oscilloscope probe 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.
- Lowest power consumption: 100-mW typical power consumption enables system designers to pack in more channels and features into smaller frames.
- Longer FR-4 reach: 50-percent longer reach than the competition enables greater flexibility when routing signals across backplanes and long board traces. The LMH0366 can equalize up to 60 inches of FR-4 trace length compared to 40 inches with the nearest competitor's device.
- No reference crystal required: Unlike competing devices that require an external reference crystal to lock to the correct data rates, the LMH0366 automatically detects the incoming data rate without the need for additional external crystals. This simplifies system design and reduces cost.
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 SMPTE 424M, SMPTE 292M, and SMPTE 259M-C standards for transmitting high-resolution uncompressed video signals.
Tools and support
The SD3GDAIII EVM is available to accelerate the development of systems using the LMH0366 and LMH0376 for a suggested retail price of US$499. IBIS models for the LMH0366 and LMH0376 are also available to verify board signal-integrity requirements.
Availability, packaging and pricing
The LMH0366 is available in a 4- x 4-mm, 24-pin QFN package for a suggested retail price of US$19.95 in 1,000-unit quantities. The LMH0376 is offered in a 7- x 7-mm, 48-pin QFN package for a suggested retail price of US$21.50 in 1,000-unit quantities.
