2-Wire Interface Slave Address
Programming
Connect DEV_ADDR to G_DIG or V_DIG to set the
MAX4399 write and read addresses as shown in
Table
2.
Data Register Writing and Reading
Program the SCART video and audio switches by writ-
ing to registers 00h through 0Dh (Tables 3 through 18).
Registers 00h through 0Dh can also be read, allowing
read-back of data after programming and facilitating
system debugging. The status register is read-only and
can be read from address 0Eh (
Table
19).
Applications Information
Filtering of Encoder Outputs
The DAC outputs of encoder chips need to be
processed through a lowpass filter (reconstruction filter)
to attenuate out-of-band noise.
Figure
9 shows how the
MAX7440 provides an integrated, convenient solution for
reconstruction filtering.
