May I set DDC_A0 unidirectional (left to right)?
And How I set it?
DDC is a bidirectional bus. Those switches you have circled automatically switch direction depending on the data flow direction. Keep in mind DDC is an I2C implementation so you any interface that meets ~800pF load cap and ~2K pullup will work.
Is this duplicate of this thread at AD8192 Input Schematic for DDC bus?
Could you give me suggestion?
one more question,
What is the DDC buffer driving ability (current)?
- The AD8192 if having the push-pull ability? - What is AD8192 automatic switch mechanism?
Could you provide the bidirectional bus Equivalent Circuit? TKS
