描述 Description

The 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. Most embedded controllers are supported. The I/O interface voltage between 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.
CH7024 is offered in 48-pin LQFP package (7 x 7 mm). CH7024 48-pin LQFP package comes with fixed single serial port address.
