Description

1, 4

DGND

Ground

Ground for Digital Supply.

2

DVDDIO

Power

Digital I/O Power Supply (1.8 V or 3.3 V).

3, 13

DVDD

Power

Digital Power Supply (1.8 V).

5 to 12

P7 to P0

Output

Video Pixel Output Ports.

14

XTALP

Output

Connect this pin to the external 28.63636 MHz crystal, or leave it unconnected if an external

1.8 V, 28.63636 MHz clock oscillator source is used to clock the ADV7281. The crystal used

with the ADV7281 must be a fundamental crystal.

15

XTALN

Input

Input Pin for the External 28.63636 MHz Crystal. The crystal used with the ADV7281must be

a fundamental crystal. If an external 1.8 V, 28.63636 MHz clock oscillator source is used to

clock the ADV7281, the output of the oscillator is fed into the XTALN pin.

16

PVDD

Power

PLL Power Supply (1.8 V).

17, 18,

24, 25

AIN1 to AIN4

Input

Analog Video Input Channels.

19

VREFP

Output

Internal Voltage Reference Output.

20

VREFN

Output

Internal Voltage Reference Output.

21

AVDD

Power

Analog Power Supply (1.8 V).

22

DIAG1

Input

Diagnostic Input 1.

23

DIAG2

Input

Diagnostic Input 2.

26

INTRQ

Output

Interrupt Request Output. An interrupt occurs when certain signals are detected on the

input video.

27

RESET

Input

System Reset Input (Active Low). A minimum low reset pulse width of 5 ms is required to

reset the ADV7281 circuitry.

28

ALSB

Input

This pin selects the I2C write address for the ADV7281. When ALSB is set to Logic 0, the

write address is 0x40; when ALSB is set to Logic 1, the write address is 0x42.

29

SDATA

Input/output

I2C Port Serial Data Input/Output.

30

SCLK

Input

I2C Port Serial Clock Input. The maximum clock rate is 400 kHz.

31

PWRDWN

Input

Power-Down Pin. A logic low on this pin places the ADV7281 in power-down mode.

32

LLC

Output

Line-Locked Output Clock for Output Pixel Data. The clock output is nominally 27 MHz, but

it increases or decreases according to the video line length.

EPAD (EP)

Exposed Pad. The exposed pad must be connected to DGND.
