DS90UB953-Q1: DS90UB953-Q1_running in the 2-Gbps mode

Part Number: DS90UB953-Q1
Other Parts Discussed in Thread: DS90UB960-Q1,

Hi...

My customer is testing the board of DS90UB953-Q1 + DS90UB960-Q1, but the video output is broken when DS90UB953-Q1 is running in the 2-Gbps mode only.

There are the descriptions on this lower data rates in datasheet as followas. (Page 13~14, 7.5.4 High Speed Data Out Signals)

"This AC-coupling capacitor is 0.033 μF when the device is running in the 4-Gbps mode. At lower data rates, a larger coupling cap is required."

What are the recommended values of coupling capacitors at lower data rates?

Please let me know that.

Regards

Jeffrey
