Printed Circuit Board Video Field Tilt Corrector -Image

Printed Circuit Board Video Field Tilt Corrector

Blocking capacitors and inductive loads will limit the low-frequency response in a video transmission network. The result is field tilt that, if excessive, may ruin sync and picture quality. The field tilt at a cut-off frequency of 1Hz will be 5.1%, at

10Hz, 40.8%. A common cut-off frequency recommendation for video transmission is 5Hz (23% tilt).

The NH16580 Video Field Tilt Corrector will restore the original waveform with minimal residual tilt.

The input of the NH16580 is ac-coupled, and provides ac-coupled and DC-coupled outputs.

The DC-coupled output can be used with devices such as: televisions, flat-panel displays, DVD players, digital camcorders, digital still cameras, video-capable cell phones, portable video game consoles, PDAs and notebook computers.

Some video equipment requires ac-coupling on its input to protect the equipment from any short circuit to ground. The NH16580 provides this protection and the ac-coupled output can also be used if you need to remove the dc-biased output and set your own levels.
