Part Number: DS125MB203
Other Parts Discussed in Thread: DS100MB203,

Hello

Would like to have the layout routing guideline- including the max trace length or insertion loss before and after the Repeater/Redriver, and the lane-to-lane length matching requirement.

Application: HDMI2.1

Thanks.

    Hi,

    You can follow the guidelines outlined in the layout section of the datasheet. You can also reference the layout shown in the DS100MB203 EVM user's guide. This device is very similar to DS125MB203 with the key difference being data rates supported.

    DS125MB203 can compensate up to 30-inch FR-4 traces. Receive equalization can compensate up to 30 dB at 6.25 GHz.

    Best,

    Lucas
