Pin Description
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.
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.
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.
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”.
