General Description
The CH7023/CH7024 is a TV encoder device targeting
handheld, portable video applications such as digital
still cameras and similar portable embedded systems.
The device is able to encode the video signals and
generate synchronization signals for NTSC and PAL
standards.
Supported TV output formats are NTSC-M, NTSC-J,
NTSC-433, PAL-B/D/G/A/I, PAL-M, PAL-N and PAL-
60.
The device accepts different data formats including
RGB and YCrCb (e.g. RGB565, RGB666, RGB888,
ITU656 like YCrCb, etc.) via 24 bit/18 bit/15 bit /12 bit
/8 bit multiplexed digital inputs.
controllers are supported. The I/O interface voltage
between CH7023/CH7024 and digital video source
controller can be selected by the I/O supply voltage
(VDDIO). The I/O supply voltage range is from 1.2V to
3.3V. The digital input voltage will follow the I/O
supply voltage.
CH7023/CH7024 is offered in both 48-pin LQFP
package (7 x 7 mm) and 49-pin TFBGA package (6 x 6
mm). CH7023/CH7024 48-pin LQFP package comes
with fixed single serial port address while 49-pin
TFBGA package provide two user selectable serial port
addresses via AS pin pull up or pull down option. Refer
to application note AN-98 for more information.
