Does the Y/C output of ADV7393 be connected as differential o/p?

rajneesh.j on Jun 14, 2018

Hi All,

Greetings!!

I am using the video encoder IC ADV7393 to encode 16bit RGB to Y/C output. But as per the requirement, the output should be differential Y_p/n and C_p/n output. Can the single ended outputs be connected directly to differential output pins of external connector or a single ended to differential converter is required? Or can you suggest a different part that meets the requirement (Analog, 1VP-P terminated condition, differential, 75Ohm).

A block diagram is attached along with.

Thanks and regards,

Rajneesh J

Hi,

Do I need a single ended to differential converter in between?

yes,please refer below receiver/decoder example for differential output support.

Are you looking for CAT5 type drivers/receivers?

or op amp style amplifiers like the AD8042

      http://www.analog.com/en/products/audio-video/video-amplifiers-analog-video-functions/video-op-amps.html

   And also please refer ADV7125 DAC but it is a digital input and analog differential output

      http://www.analog.com/en/products/digital-to-analog-converters/standard-dac/high-speed-da-converters/adv7125.html#product-overview.

And also refer below thread for reference.

video line driver and receiver for differential input and output

Beleive that this would be helpful.

Thanks,
