TDA9897; TDA9898
Multistandard hybrid IF processing
9.1 Read format
[1]
If no IF input is applied, then bit AFCWIN can be logic 1 due to the fact that the VCO is forced to the AFC
window border for fast lock-in behavior.
[2]
All standards except M/N standard.
[3]
M/N standard.
[4]
Typical time constant of FM carrier detection is 50 ms. The minimal recommended wait time for read out is
80 ms.

1 = VCO in
±0.8 MHz AFC window[3]
0 = VCO out of
±1.6 MHz AFC window[2]
0 = VCO out of

BLCKLEV
black level detection
1 = black level detected
0 = no black level detected

CARRDET
FM carrier detection[4]
1 = detection (FM PLL is locked and level is less than 6 dB below gain
controlled range of FM AGC)
0 = no detection

AFC[4:1]
automatic frequency control; see Table 8

PONR
power-on reset
1 = after power-on reset or after supply breakdown
0 = after a successful reading of the status register
