Pixel Data Pins

Figure 3-2 shows the following:

• The relationship of:

– Outputs from the ICS1531 ADC

– To inputs of a 1024

× 768 LCD panel that samples 2 pixels of data with either a 36- or 48-bit data

signal.

• DA indicates ‘A channel’ pixels, and DB indicates ‘B channel’ pixels.)

For timing information, see Chapter 10, “Timing Diagrams”.

Pixel Data Pins

Name

Type

Pin Description

ABLUE,

AGRN,

ARED

Input

Analog Blue, Analog Green, Analog Red.

• These pins accept analog data for the ADC blue, green, and red channels.

• Typically, the data for these pins comes from a PC display controller.

BA7 – BA0,

GA7 – GA0,

RA7 – RA0

Output

Blue (‘A channel’) A7 – A0, Green (‘A channel’) A7 – A0, Red (‘A channel’) A7 – A0.

• These pins output first blue, green, and red pixel data, respectively.

• A7 pins reflect most-significant data bits. A0 pins reflect least-significant data bits.

BB7 – BB0,

GB7 – GB0,

RB7 – RB0

Output

Blue (‘B channel’) B7 – B0, Green (‘B channel’) B7 – B0, Red (‘B channel’) B7 – B0.

• These pins output second blue, green, and red pixel data, respectively.

• B7 pins reflect most-significant data bits. B0 pins reflect least-significant data bits.
