ADV7170/ADV7171

The ADV7170/ADV7171 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. Addi-

tionally, 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 tim-

ing modes. For a detailed explanation of each bit in the com-

mand 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.
