Interpolation ratio select
Table 11.
The STA333W has variable interpolation (oversampling) settings such that internal
processing and DDX output rates remain consistent. The first processing block interpolates
by either 2 times or 1 time (pass-through) or provides a 2-times downsample. The
oversampling ratio of this interpolation is determined by the IR bits.
Table 12.
Thermal warning recovery bypass
Table 13.
If the thermal warning adjustment is enabled (TWAB = 0), then the thermal warning
recovery determines if the -3 dB output limit is removed when thermal warning is negative.
If TWRB = 0 and TWAB = 0, then when a thermal warning disappears the -3 dB output limit
is removed and the gain is added back to the system. If TWRB = 1 and TWAB = 0, then
when a thermal warning disappears the -3 dB output limit remains until TWRB is changed to
zero or the device is reset.
