Hi. I am writing driver code for SGTL5000 audio codec. The voltage I am using for the codec is VDDIO=3.3v, VDDA=3.3v and VDDD=1.8v.
As the voltage level is different from other reference board, I want someone double check the register values that needs to be configured for my case. The values I am trying to use is like below.
Write CHIP_ANA_POWER 0x4260
Write CHIP_LINREG_CTRL 0x006C
Write CHIP_REF_CTRL 0x01FF
Write CHIP_LINE_OUT_CTRL 0x0322
Write CHIP_REF_CTRL 0x004F
Write CHIP_SHORT_CTRL 0x1106
Write CHIP_ANA_CTRL 0x0133
Write CHIP_ANA_POWER 0x6AFF
Write CHIP_DIG_POWER 0x0073
Write CHIP_LINE_OUT_VOL 0x0505
As I use external VDDD. Can you check whether any additional value needs to be applied?
Also I want to know whether external VDDD can be used on the latest SGTL5000 device (revision:0x11).
Thank you.
James.
