DS90UB926Q-Q1: Question about DS90UB926Q-Q1

Other Parts Discussed in Thread: DS90UH926Q-Q1

Hello：

1、The customer requested DS90UB926QSQX/NOPB, but could not pull in. I would like to confirm if the UH version is available？（DS90UH926Q-Q1）

2、For the definition of pin pin, pin 60 has been changed to Mclk. On the OBU, this pin is grounded. Do you need to confirm if there is a problem with MCLK grounding?

    Hi Jimmy,

    1. Could you clarify the pull-in? Are you asking if the customer is possible to use UH926 instead of UB926? Note that the difference between UB and UH is HDCP feature. Swapping from UB and UH does not have any hardware changes and would just require a different software configuration depending on what features the customer wishes to enable. 
    2. Not sure what OBU means, but MCLK is I2S Master Clock Output. It is not connected to GND. Please refer to the below.

    Best,

    Josh
