BT1026 series pin9 MCLK

Baursaque

Hello!
For FSC-BT1026B/C/D/E in I2S master mode, does pin 9 (PCM_MCLK_OUT/PIO15) output MCLK? If yes, what is the MCLK frequency or MCLK/LRCK ratio at 44.1 kHz and 48 kHz? Is any firmware configuration required to enable MCLK_OUT?

Baursaque For the standard firmware of the FSC-BT1026B/C/D/E, Pin 9 (PCM_MCLK_OUT/PIO15) is left floating and MCLK output is not enabled.

If you need to use the MCLK output, firmware customization is required. Please contact your sales representative to discuss the customization requirements.
