CH7024

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.

CH7024 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. Most embedded 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.
