TDA2HG: Manual Question

Pete Staniak
Prodigy 120 points

Part Number: TDA2HG

In the manual under power supply descriptions:   

The signal name is is vddshv3 with a description of: Dual Voltage (1.8V or 3.3V) power supply for the GENERAL Power Group pins

Could you please tell me what these GENERAL Power Group pins are?  Do they include the Multi-channel Audio Serial Port (McASP) ?  

Finally,  is there any documentation from TI that has more information about McASP being useful for time-division multiplexed (TDM) stream?

Cheers,

Pete

    Hi Pete,

    Please disregard references to power groups. They are legacy and have little meaning to users.

    Instead, please make a search in the DM for 'vddshv3' in Table 4-2. Ball Characteristics. You will find all device balls powered through vddshv3. And yes, MCASP is one of them.

    For MCASP hardware and low-level software, good starting point is the MCASP chapter in the device TRM.

    For linux driver please see the below document:

    Regards,

    Stan
