ASX340CS: 1/4-Inch Color CMOS NTSC/PAL Digital Image Sensor

Modes and Timing

This section provides an overview of the typical usage modes and related timing infor-

mation for the ASX340AT.

Composite Video Output

The external pin DOUT_LSB0 can be used to configure the device for default NTSC or PAL

operation (auto-config mode). This and other video configuration settings are available

as register settings accessible through the serial interface.

NTSC

Both differential and single-ended connections of the full NTSC format are supported.

The differential connection that uses two output lines is used for low noise or long

distance applications. The single-ended connection is used for PCB tracks and screened

cable where noise is not a concern. The NTSC format has three black lines at the bottom

of each image for padding (which most LCDs do not display).

PAL

The PAL format is supported with 576 active image rows.

Single-Ended and Differential Composite Output

The composite output can be operated in a single-ended or differential mode by simply

changing the external resistor configuration. Refer to the Developer Guide for configura-

tion options.

Parallel Output (DOUT)

The DOUT[7:0] port supports both progressive and Interlaced mode. Progressive mode

(with FV and LV signal) include raw bayer(8 or 10 bit), YCbCr, RGB. Interlaced mode is

CCIR656 compliant.

Figure 29 shows the data that is output on the parallel port for CCIR656. Both NTSC and

PAL formats are displayed. The blue values in Figure 29 represent NTSC (525/60). The

red values represent PAL (625/50).
