mode of the device (see Table 4). In GBR mode, the output drive is identical on the three channels, while in

YPbPr mode, a level shift is implemented on Pb and Pr channels. Refer to the application information section

for details on the current drive levels in each mode.

The device has an internal voltage reference derived from a bandgap reference of 1.35 V. The relationship

where

α is dependent on the operation mode of the device.

current levels mentioned in Table 4 and, when terminated, voltages of standard video levels, as shown in the

applications section. The resistor value is variable provided the maximum current level on each of the DAC

outputs is not exceeded.
