I2S Pin Configuration for RD160

ROSE Products RD160
#1

Morning @ROSEHAN,

On the RS130, there are two I2S pin configurations, A MODE and B MODE.

Which mode is used on the RD160 when connecting to the RS130 via I2S cable ?

@TomT

When connecting RS130 and RD160 with i2S, set it to A mode and use it.

Hi @ROSEHAN,

what if I want to connect an RS150B via the DVI/I2S connector for the RD160?

Based on the DVI to HDMI pin mapping provided by @ROSELOA 2 years ago (I2s to external DAC - #6 by ROSELOA), it seems that its close to the I2S B-Mode configuration of the RS150B. Saying that, to how I read it, the + and - Data signals seem to be swapped.

Is this correct?

Thanks and best regards,

Tom

When connecting RS150b and RD160 via I2S, you can use an HDMI to DVI Cable to connect via I2S.

When connecting the RS150B to the RD160 via I2S, we recommend using B-Mode on the RS150B.

The I2S pin configuration of the RS150B in B-Mode is the closest match to the I2S input of the RD160. However, please note that there may be differences in signal polarity (e.g., Data+ and Data–) between the two devices, which could potentially affect signal stability or playback.
