Frequently asked questions

Which video standards are supported by Analog Devices video RAM-DACs?

Analog Devices parts can output NTSC, PAL, or SECAM video formats.

What is the blank to white voltage level for RS-170?

The RS-170 standard specifies a blank to white level of 1V.

How can different video standards be implemented using Analog Devices DACs?

Standards are implemented by varying the value of the source termination resistance (Zs) in a doubly terminated configuration.
