LMH1981MT Description

Short technical summary and product information.

The LMH1981MT from Texas Instruments is a versatile multi-format video sync separator designed for broadcast and professional video equipment, including HDTV/DTV systems. It accepts standard analog SD/ED/HD video signals with bi-level or tri-level sync.

This device provides critical timing signals such as Composite, Horizontal, and Vertical Syncs, Burst/Back Porch Timing, Odd/Even Field, and Video Format Outputs in CMOS logic. It features superior jitter performance on the leading edge of HSync, minimizing the need for external jitter reduction circuitry. The LMH1981MT automatically detects the input video format, simplifying integration and eliminating the need for microcontroller programming.

Key electrical specifications include a core supply voltage range of 3.3V to 5V and an output supply voltage range of 3.3V to 5V. The input accepts CMOS signals and supports video input signal amplitudes from 0.5 V PP to 2 V PP with 50% sync slicing for accurate sync extraction. The operating temperature range is -40°C to 85°C.

The LMH1981MT is housed in a 14-pin TSSOP (PW) package with dimensions of 5 mm x 6.4 mm, covering an area of 32 mm². It is suitable for applications requiring reliable and precise video synchronization.
