I'm using the TAS5162DDV6EVM. I have a clean, stable 12V, 5V, and 3.3V on the board. PVDD @ 48V is also stable.
VR_DIG and VR_ANA have a good 1.8V.
I have no problems reading and writing to the TAS5086.
LRCLK = 96KHZ
SCLK = 6.144MHZ (64*FS)
MCLK = 0V (pulled low, using auto-detect with internal PLL)
OTW = 3.3V
SD = 3.3V
VALID2 = 0V (here's the problem)
The SE outputs are at 12V with respect to ground. The BTL outputs are at 1.4V with respect
to ground. The same condition persists with the USB input board (supplied with TAS5162DDV6EVM)
as well as my logic board (designed by myself, uses microcontroller and TAS3103A). With the USB input
board the ERROR STATUS REGISTER was read as 0x00 (no errors).
Any advice would be greatly appreciated.
