MT9V125: SOC VGA Digital Image Sensor

Modes and Timing

Progressive

The DOUT[7:0] port also supports progressive, raw data output. The on-chip color

processor does not support reading out the pixel array progressively, but the raw pixel

data can be made available in sensor stand-alone mode.

Parallel Input (DIN)

The data-in port allows external CCIR656 data to be multiplexed into the NTSC or PAL

output data. Figure 29 shows the timing of the data-in (D

IN[7:0]) signals. Table 13

describes timing values for the parallel input waveform. Both mode 0 and mode 1 wave-

forms are supported by the MT9V125.

Figure 29: Parallel Input Data Timing Waveform Using DIN_CLK

Notes: 1. If R19:1[4] = 1, then DIN_CLK is used to sample data on DIN bus.

2. Setup and hold time is measured with respect to the rising or falling edge of DIN_CLK which can be

programmed by R19:1[3].
