ch7317b-利来app官网

the ch7317b is a display controller device interfaces seamlessly to hdtv or pc monitors that is equipped with a vga rgb interface display connector. its input port, complied with intel sdvo specification 1.2, can accept a digital graphics, high-speed, ac-coupled, serial-differential rgb input signal, and convert it to analog rgb signal for driving the display.

the ch7317b supports maximum pixel rate of 165mp/s and is capable of displaying up to 1920x1200 resolution with reduced blanking. the built-in serial port controller will allow the graphics chipset to obtain the monitor’s edid information or communicate with ch7317b internal registers through sdvo opcodes. in addition, the transmitter is designed with a monitor connection detection algorithm that allows the graphics chipset to read back the connection status through ch7317b internal registers.

the ch7317b provides the boundary-scan test to help system developers to check the interconnection between chip i/o and the printed circuit board for faults. when the device is powered down by the graphics chipset, its current consumption is less than 100ua. the ch7317b is available in 64-pin lqfp and 64-pin qfn packages.
