DS90UB949-Q1: DS90UB949-Q1 hardware design support

Part Number: DS90UB949-Q1

Hi 

I am using DS90UB949-Q1 (1080p HDMI to FPD-Link III Bridge Serializer) part in my application

I have some hardware design related queries on this part

1.For Single Link Operation mode all 3 TMDS Data Channel inputs are required or  any one inputs is fine?If any one input channel is enough, then what i need to do for remaining input channel signal? Shall I Keep NO connection or need to pull down with any specific resistor value?

2. Some of pins are not going to use in my application. For Unused pins Shall I Keep NO connection or need to pull down with any specific resistor value?

SPI/GPIO pins - pin number 8,10,11,12

I2S pins - pin 33 to 36

X1 - pin 39

MCLK - pin 16

Best Regards,

Mahesh
