Description
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).
3, 10, 24, 57
DGND
G
Digital Ground.
4, 11
DVDDIO
P
Digital I/O Supply Voltage (3.3 V).
28 to 25, 19 to 12, 8 to 5,
62 to 59
P0 to P19
O
Video Pixel Output Port. Refer to Table 10 for output configuration modes.
9
SFL/SYNC_OUT
O
SFL: 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.
SYNC_OUT: Sliced Synchronization Output Signal Available Only in CP Mode.
20
LLC
O
Line-Locked Output Clock. This pin is for the pixel data (the range is
12.825 MHz to 110 MHz).
21
XTAL1
O
This pin should be connected to the 28.63636 MHz crystal or left as a no connect
if an external 3.3 V, 28.63636 MHz clock oscillator source is used to clock the
ADV7181C. In crystal mode, the crystal must be a fundamental crystal.
22
XTAL
I
Input pin for 28.63636 MHz crystal, or can be overdriven by an external 3.3 V,
28.63636 MHz clock oscillator source to clock the ADV7181C.
23, 58
DVDD
P
Digital Core Supply Voltage (1.8 V).
29
PWRDWN
I
A Logic 0 on this pin places the ADV7181C in a power-down mode.
30
ELPF
O
The recommended external loop filter must be connected to this ELPF pin.
31
PVDD
P
PLL Supply Voltage (1.8 V).
32, 37, 43
AGND
G
Analog Ground.
