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

adv7343_1: endpoint {
|
||
|
|
adi,power-mode-sleep-mode;
|
||
|
|
adi,power-mode-pll-ctrl;
|
||
|
|
/* Use DAC1..3, DAC6 */
|
||
|
|
adi,dac-enable = <1 1 1 0 0 1>;
|
||
|
|
/* Use SD DAC output 1 */
|
||
|
|
adi,sd-dac-enable = <1 0>;
