1
INT
O
Interrupt. This pin can be active low or active high. When SDP/CP status bits
change, this pin is triggered. The set of events that triggers an interrupt is
under user control.
2 HS/CS O
HS: Horizontal Synchronization Output Signal (SDP and CP Modes).
CS: Digital Composite Synchronization Signal (CP Mode).
64 VS O Vertical Synchronization Output Signal (SDP and CP Modes).
63 FIELD/DE O
Field Synchronization Output Signal (All Interlaced Video Modes). This pin also
can be enabled as an data enable signal (DE) in CP mode to allow direct
connection to a HDMI/DVI Tx IC.
53 SDATA I/O I
2
C Port Serial Data Input/Output Pin.
54 SCLK I I
2
C Port Serial Clock Input. Maximum clock rate of 400 kHz.
52 ALSB I
This pin selects the I
2
C address for the ADV7181C control and VBI readback
ports. ALSB set to Logic 0 sets the address for a write to Control Port 0x40 and
the readback address for VBI Port 0x21. ALSB set to a Logic 1 sets the address
for a write to Control Port 0x42 and the readback address for VBI Port 0x23.
