very low jitter, minimizing external circuitry needed to clean and reduce jitter in subsequent sync processing stages. The LMH1981 automatically detects the input video format, eliminating the need for programming using a microcontroller or external RSET resistor. The sync separator applies precise 50% sync slicing to ensure accurate sync extraction for inputs with irregular amplitude, offset, and noise conditions. Its unique video format feature (pin 9) outputs the total vertical scan lines per frame as an 11-bit binary serial bit stream, which can be decoded by the video system to determine ... |
