ch7518-利来app官网

chrontel’s ch7518 is a low-cost, low-power semiconductor device that translates the displayport signal to the bt656 or 8 bit ycbcr 4:2:2 signal. this innovative displayport receiver with an integrated bt656 encoder is specially designed to target the notebook/ultrabook, tablet device and automobile entertainment device. through the ch7518’s advanced decoding / encoding algorithm, the input displayport high-speed serialized multimedia data can be seamlessly converted to bt656 video and iis or spdif audio output.

the ch7518 is compliant with the displayport specification 1.2 and the embedded displayport specification version 1.3. with internal hdcp key integrated, the device support hdcp 1.3 specifications. in the device’s receiver block, which supports two displayport main link lanes input with data rate running at either 1.62gb/s or 2.7gb/s, can accept rgb digital formats in either 18-bit 6:6:6 or 24-bit 8:8:8, and converted the input signal to 8 bit ycbcr output signal up to 1280 x 720@60hz. leveraging the displayport’s unique source/sink “link training” routine, the ch7518 is capable of instantly bring up the video display to the device of bt656 input when the initialization process is completed between ch7518 and the graphic chip.

with sophisticated mcu and the boot rom embedded, ch7518 support auto-boot and edid buffer. after the configuration by firmware, which is auto loaded from boot rom, ch7518 can support dp input detection, and determine to enter into power saving mode automatically.
