1 | * Analog Devices adv7343 video encoder | ||
2 | |||
3 | The ADV7343 are high speed, digital-to-analog video encoders in a 64-lead LQFP | ||
4 | package. Six high speed, 3.3 V, 11-bit video DACs provide support for composite | ||
5 | (CVBS), S-Video (Y-C), and component (YPrPb/RGB) analog outputs in standard | ||
6 | definition (SD), enhanced definition (ED), or high definition (HD) video | ||
7 | formats. | ||
8 | |||
9 | Required Properties : | ||
10 | - compatible: Must be "adi,adv7343" | ||
11 | |||
12 | Optional Properties : | ||
13 | - adi,power-mode-sleep-mode: on enable the current consumption is reduced to | ||
14 | micro ampere level. All DACs and the internal PLL | ||
15 | circuit are disabled. | ||
16 | - adi,power-mode-pll-ctrl: PLL and oversampling control. This control allows | ||
17 | internal PLL 1 circuit to be powered down and the | ||
18 | oversampling to be switched off. | ||
19 | - ad,adv7343-power-mode-dac: array configuring the power on/off DAC's 1..6, | ||
20 | 0 = OFF and 1 = ON, Default value when this | ||
21 | property is not specified is <0 0 0 0 0 0>. | ||
22 | - ad,adv7343-sd-config-dac-out: array configure SD DAC Output's 1 and 2, 0 = OFF | ||
23 | and 1 = ON, Default value when this property is | ||
24 | not specified is <0 0>. | ||
