Especially when system needs 1080p (12bit) data rate, deterioration of Jitter tolerance is outstanding. This problem also depends on receiver IC characteristic. When 1080p (12bit) is required , Rohm doesn’t recommend cascade connect application.

But even connecting AC coupling capacitor, AC current may flow if input common mode voltage between two devices is different. This AC current may damage the lower common mode voltage devices like PCIe or DisplayPort. 6) TMDS output offset voltage Offset voltage may appear to TMDS output when there is no signal to TMDS input differential line. OE should be set to “H” to avoid it. www.rohm.com © 2011 ROHM Co., Ltd.
