I / O

Function

2 ~ 8

GD (7: 0)

G data input pin for 24-bit RGB input.

Y data input pin for 16-bit YUV input.

11 ~ 14

17 ~ 20

BD (7: 0)

B data input pin for 24-bit RGB input.

U, V data input pins for 16-bit YUV

input.

Control pins used to select RGB (24-

bit), YUV (16-bit) or DAC Through as

the input mode.

CDGSWB

Switches the mode between Video-

CD (HIGH) and CD-G (LOW).

54 ~ 56

58 ~ 60

62.63

RD (7: 0)

R data input pin for 24-bit RGB input.

ROSD

GOSD

BOSD

OSDSW

OSD data input pin when using the

OSD function.

When the OSDSW pin is HIGH, input

to the ROSD, GOSD, and BOSD pins

takes precedence over RGB, and the

data is converted.

IM0

IM1

NTB

Switches the mode between NTSC

(LOW) and PAL (HIGH).

HSY

I / O

This is the horizontal synchronization

signal pin. Negative polarity HSYNC

signals are input (when SLABEB =

LOW) or output (when SLABEB =

HIGH) here. This is also used as the

synchronization signal for fixing the

PIXCLK output phase.
