Register List
Note:
AV_DELAY acts on both LS and HP paths simultaneously (same delay).
12.12 Automatic Standard Recognition
AUTOSTD_CTRL
Automatic Standard Recognition Control Register
Note:
Only standard deviation FM 50K kHz is compatible with other D/K1/K2/K3 standards in Automatic
Standard Recognition Search mode.
FM deviation superior to 350 kHz will degrade strongly NICAM reception due to overlapping of FM
and QPSK IF spectrum in DK-NICAM standard.
