SN65DP159: Signal Integrity Analysis

user5803443

Part Number: SN65DP159
Other Parts Discussed in Thread: SN75DP159,

Hi,

I look at the SN75DP159 IBIS-AMI Models User’s Guide for SI Analysis of SN65DP159. I did not find description and purpose of the below pins.

Votting Threshold = 7,

Settling Tİme = 7,

EQ = 0,

HorL = 0,

Slew_CTL = 0,

TX_TERM_CTL = 0,

Can you describe this pin?

When I changed this pins value, What can I see?

Best Regard

I would recommend not changing the Voting Threshold and Setting Time and leave them as is.

For EQ, please refer to the DP159 datasheet.

HorL = 0 low frequency is 3G, HDMI1.4, and HorL = 1 high frequency is 6G, HDMI2.0

TX_Term_CTL = low, no termination HDMI1.4, middle is 150-300 for HDMI1.4, and high is 75-150 for HDMI2.0.

Slew_CTL please refer to the DP159 datasheet.

It is best to sweep the various combination that would result in the best eye diagram in the simulator.

Thanks

David
