The LMH1980 is an auto-detecting SD/HD/PC video sync separator ideal for use in a wide range of video applications, such as automotive LCD monitors, video capture & editing devices, surveillance & security equipment, and machine vision and inspection systems. It automatically detects the video format, eliminating the need for external RSET resistor adjustment required by other sync separators. The outputs provide timing signals in CMOS logic, including Composite, Horizontal, and Vertical Syncs, Burst/Back Porch Timing, and Odd/Even Field outputs. The HD flag output provides a logic low signal only when a valid HD video input with tri-level sync is detected. It can be used to disable an external switch-controlled SD chroma filter when HD video is detected, or enable it when SD video is detected. For non-standard video with bi-level sync and without vertical serration pulses, a default vertical sync pulse will be output and no horizontal sync pulses will be output during the vertical sync interval. The LMH1980 is available in a space-saving 10-ld. Mini-SO Package (MSOP) and operates over a temperature range of −40°C to +85°C.
