Hi 陳 冠儒  

this depends on which pad is used as SPDIF_IN, for example

if EIM_D21(ALT7), then one can find which power domain powers this pad.

Please use Table 100. 21 x 21 mm Functional Contact Assignments

i.MX6DQ Datasheet (rev.4, 7/2015)

http://cache.freescale.com/files/32bit/doc/data_sheet/IMX6DQCEC.pdf

NVCC_EIM0 is power domain for EIM_D21 pad. Then check what is its voltage

on your board. Knowing it, find voltage levels using sect.4.7.1 General Purpose I/O AC Parameters

Datasheet.

Best regards

igor

But

But I have another question, how can the two HDMI (one original, one is converted through 7036), when inserted into the original HDMI can play sound when pulled out ,another inserted after the original 7036's HDMI ,HDMI can playing sound.

how switch it? OR auto switch?

Please help me,thanks.

(中譯:

但是我有另一個問題,如何能使兩個HDMI(一個是原始的,一個是經過7036轉換的),當插入原始的HDMI 能夠播放聲音,當拔掉原始的HDMI插入另一個經過7036的HDMI也能夠播放聲音呢?

如何能夠切換呢?或自動轉換音源到某一輸出呢?
