DGND
G
Digital Ground.
2, 4
DVDDIO
P
Digital I/O Supply Voltage (1.8 V to 3.3 V).
3
SFL
O
Subcarrier Frequency Lock. This pin contains a serial output stream that can be used to lock the
subcarrier frequency when this decoder is connected to any Analog Devices digital video encoder.
5, 6, 41, 42
GPO0 to GPO3
O
General-Purpose Outputs. These pins can be configured via I2C to allow control of external devices.
7 to 12, 20, 22
P7 to P2, P1, P0
O
Video Pixel Output Port. S
ee Table 100 for output configuration for 8-bit and 16-bit modes.
14
LLC
O
This is a line-locked output clock for the pixel data output by th
e ADV7180. It is nominally
27 MHz but varies up or down according to video line length.
15, 48
NC
No Connect Pins. These pins are not connected internally.
16
XTAL1
O
This pin should be connected to the 28.6363 MHz crystal or left as a no connect if an external 1.8 V,
28.6363 MHz clock oscillator source is used to clock
the ADV7180. In crystal mode, the crystal
must be a fundamental crystal.
17
XTAL
I
This is the input pin for the 28.6363 MHz crystal, or this pin can be overdriven by an external 1.8 V,
28.6363 MHz clock oscillator source. In crystal mode, the crystal must be a fundamental crystal.
18, 44
DVDD
P
Digital Supply Voltage (1.8 V).
21
PWRDWN
I
A logic low on this pin places th
e ADV7180 in power-down mode.
23, 28, 32
AGND
G
Analog Ground.
24
ELPF
I
The recommended external loop filter must be connected to the ELPF pin, as shown
in Figure 59.25
PVDD
P
PLL Supply Voltage (1.8 V).
26, 27, 33 to 36
AIN1 to AIN6
I
Analog Video Input Channels.

VREFP
O
Internal Voltage Reference Output. S
ee Figure 59 for recommended output circuitry.

VREFN
O
Internal Voltage Reference Output.
See Figure 59 for recommended output circuitry.

AVDD
P
Analog Supply Voltage (1.8 V).
37
RESET
I
System Reset Input. Active low. A minimum low reset pulse width of 5 ms is required to reset
38
ALSB
I
This pin selects the I2C address for the ADV7180. For ALSB set to Logic 0, the address selected for a write is Address 0x40; for ALSB set to Logic 1, the address selected is Address 0x42.
39
SDATA
I/O
I2C Port Serial Data Input/Output Pin.
40
SCLK
I
I2C Port Serial Clock Input. The maximum clock rate is 400 kHz.
45
VS/FIELD
O
Vertical Synchronization Output Signal/Field Synchronization Output Signal.
46
INTRQ
O
Interrupt Request Output. Interrupt occurs when certain signals are detected on the input video
47
HS
O
Horizontal Synchronization Output Signal.
