For the I2S external output a choice can be made between FM and AM digital radio, both

at 650 kSa/s and both wanted-signal only. All PDC input and output signals are complex.

7.1.2.16 LD interface

The SAF7741HV is designed for a generic tuner with TEF7000 architecture.

Communication between the tuner and the SAF7741HV uses the proprietary two-line LD

interface for AGC, injection-mode and bandwidth settings.

The tuner sends commands to the SAF7741HV while the SAF7741HV sends requests to

the tuner. A tuner command is always executed unconditionally by the SAF7741HV, but a

request from the SAF7741HV to the TEF7000 may be ignored.
