DS320PR810: I2C secondary mode

Part Number: DS320PR810

Hi,

In figure 8-4, mode pin needs 59kohm for 16lane/i2c secondary mode.

However, in pin description, mode pin needs 24.9kohm for i2C secondary mode.

Could you explain why these are different?

After connect external I2C to redriver SCL/SDA, SCL/SDA of redriver is pull-down.

Could you provide any guide for this issue?

Thanks.
