I2C-bus controlled single and multistandard
alignment-free IF-PLL demodulators
TDA9885; TDA9886
9.1.1
SLAVE ADDRESS
The first module address MAD1 is the standard address (see Table 1).
Table 4
Slave addresses; notes 1 and 2
Notes
1. For MAD activation via external resistor: see Table 1 and Fig.23.
2. For applications without I2C-bus: see Tables 17 and 18.
9.1.2
DATA BYTE
Table 5
Data read register (status register)
Table 6
Description of status register bits
Note
1. If no IF input is applied, then bit AFCWIN = 1 due to the fact that the VCO is forced to the AFC window border for
fast lock-in behaviour.
