C Port Serial Data Input/Output Pin.
I

C Port Serial Clock Input. Maximum clock rate of 400 kHz.
This pin selects the I
2
C address for the ADV7180. For ALSB set to Logic 0, the address
selected for a write is 0x40; for ALSB set to logic high, the address selected is 0x42.
A logic low on this pin places the ADV7180 in power-down mode.
The recommended external loop filter must be connected to the ELPF pin, as shown in
Figure 54.
System Reset Input. Active low. A minimum low reset pulse width of 5 ms is required to reset
the ADV7180 circuitry.
