SRC4190: TDM sub-frame order

Part Number: SRC4190

Tool/software:

Hi, 

Regarding SRC419x devices: When a series of chips are daisy chained, how do they each know which sub-frame they should occupy? 

Does the first device take the first sub-frame, 2nd device the 2nd sub-frame, ...?

Thanks,

    Hi Sia,

    when TDM is sent to multiple devices in parallel  usually there is a register that can shift the data based on the order we want to apply the specific input to each specific devices but for SRC4190 which is a pin programmed,  they would be connected in a daisy chain configuration of  devices in series , and  the first sub frame  goes to the first device in the chain and the second sub frame  to the second device and etc.

    Regards,
