PIN DESCRIPTIONS

I/O

Symbol

Description

1DVDD

3.3 V digital power supply.

I/O

SDA

2C interface data bus.

SCL

2C interface clock bus.

RGBMODE

Input signal select pin. "0" : YCbCr / "1" : RGB, Internal pull-down.

5 to 8

MODE[3:0]

Operation mode select pin. However, sleep mode is valid while RGBMODE

is "0". Internal pull-down.

Master/slave operation selection in other modes than ITU-R BT.656. Internal

pull-down. "1" : Master / "0" : Slave

Only slave mode is selected in ITU-R BT.656 mode (input of "1" is invalid)

I/O

GENLOCK

GENLOCK signal I/O pin.

CSYNC_L

Composite sync output pin.

I/O

VSYNC_L

Vertical sync input/output pin (output mode in master mode/input mode in

slave mode)

I/O

HSYNC_L

Horizontal signal input/output pin (output mode in master mode/input mode

in slave mode)

BLANK_L

Composite blank signal input pin.

DVDD

3.3 V digital power supply.

DGND

Digital GND.

17 to 24

CD0 to CD7

8-bit digital image chrominance signal data input pins at pixel rate

operation. Level conforms to ITU-R BT.601. R signal input pins in RGB input

mode. CD7 is MSB. Fixed to "0" when not used.

25 to 32

YD0 to YD7

8-bit digital image data input pins at double pixel rate operation. 8-bit digital

luminance signal data input pins at pixel rate operation. Level conforms to

ITU-R BT.601. G signal input pins in RGB input mode. YD7 is MSB.

FOUT

Field information output pin (Odd Field : "1", Even Field : "0") (Polarity can

be changed by the internal register.)

RESET_L

System reset pin.

TENB

Input pin for testing. Normally fixed to "0". Internal pull-down. The user

cannot use this pin.

CLKX2

Clock input pin.
