• Manufacturer: Analog Devices, Inc.

The ADV7177/ADV7178 registers can be set depending on the user standard required.
The following examples give the various register formats for several video standards.
In each case the output is set to composite o/p with all DACs powered up and with the BLANK input control disabled. Additionally,
the burst and color information are enabled on the output and the internal color bar generator is switched off. In the examples shown,
the timing mode is set to Mode 0 in slave format. TR02–TR00 of the Timing Register 0 control the timing modes. For a detailed
explanation of each bit in the command registers, please turn to the Register Programming section of the data sheet. TR07 should be
toggled after setting up a new timing mode. Timing Register 1 provides additional control over the position and duration of the timing
signals. In the examples, this register is programmed in default mode.
