i2s nomenclature

[kp93300]

Hi
I need some help as i found the i2s pin out labelling different .
My usb converter has this as i2s out : MCLK , LRCK, DATA , SCLK AND GND

My dac input has these i2s pin label : BCK, WS, DATA and GND

Is the correct alignment ?


BCK----SCLK
WS-----LRCK
DATA----DATA

GND----GND


Thanks for your help.

Correct.

Same Problem

I have a USB converter with the following I2S outputs:

LRCK
DATA
BCK
MCK
GROUND

My DAC has the following I2S inputs:

Bit Clock
Word Clock
Data
GND

Would the correct alignment be:

Bit Clock - BCK
Word Clock - LRCK
Data - DATA
GND - GROUND

??

Thanks for your help !!!!

Yes, that looks correct - the MCK isn't used.

DAC hook up

DAC has - DATA BCK LRCK GND

Digital player has DATA SCLK LRCK MCLK GND

are they compatible

DAC has - DATA BCK LRCK GND



Digital player has DATA SCLK LRCK MCLK GND



are they compatible

Yes, BCK = SCLK. Ignore MCLK as your DAC does not need it.

Thanks will give it a try

Is it possible to connect single ended I2S to LVDS I2S?

Input unit (network streamer): Matrum Acustic Ambre
Output unit (DAC): Holo Audio May

Tamu Audio sells an I2S RJ45 to HDMI adapter (https://www.aliexpress.com/item/4001249889215.html) and I wonder whether using a modified UTP cable the I2S connection between the Ambre and the May is possible via such adapter. The picture below shows how the UTP cable would connect the pins at the Ambre and Tamu ends (coloured lines).

The I2S used in the Ambre is single ended, and the Holo uses LVDS. I suppose the two cannot be connected without a conversion unit in the middle?

Thanks

LVDS uses different voltage levels as compared to LVCMOS. There are chips available to convert between the two formats, which is probably the best way to go.
