Register Descriptions
(continued)
Input Data Format Register
Symbol: IDF
Address: 04H
Bits: 6
This register sets the variables required to define the incoming pixel data stream.
RGBBP (bit 5): Setting this bit enables the RGB pass-through mode. Setting this bit to a 1 causes the input RGB
signal to be directly output at the DACs (subject to a pipeline delay). If RGBBP=0, the bypass mode is disabled.
DACG (bit 6): This bit controls the gain of the D/A converters. When DACG=0, the nominal DAC current is 71
μ
A, which provides the correct levels for NTSC and PAL-M. When DACG=1, the nominal DAC current is 76
μ
A,
which provides the correct levels for PAL and NTSC-J.
Clock Mode Register
Symbol: CM
Address: 06H
Bits: 8
The setting of the clock mode bits determines the clocking mechanism used in the CH7013A. The clock modes are
shown in the table below. PCM controls the frequency of the pixel clock, and XCM identifies the frequency of the
XCLK input clock.
