D/A Converter
M2 uses a 3 × 6-bit voltage D/A converter to generate analog RGB output signals with a
nominal amplitude of 0.7 V (also available: 0.5 V, 1.0 V and 1.2 V) peak to peak. Two
different modes are available in order to allow the reduction of power consumption for
applications which require a lower RGB bandwidth.

Function
Gain Adjustment of RGB Converter.
The user can change the output gain of the DAC.
00: 0.5 V
01: 0.7 V
10: 1.0 V
11: 1.2 V
Bandwidth Control
0: The effective bandwidth of the DAC is set to 50 MHz
1: The effective bandwidth of the DAC is set to 32 MHz. This reduces
the current consumption of analog supply.
