Chrontel’s CH7525 is a low-cost, low-power semiconductor device that translates the DisplayPort signal to HDMI/DVI. This innovative DisplayPort receiver with an integrated HDMI Transmitter is specially designed to target the notebook/ultrabook, tablet device and PC market segments. Through the CH7525’s advanced decoding / encoding algorithm, the input DisplayPort high-speed serialized multimedia data can be seamlessly converted to HDMI/DVI output.

The CH7525’s DP/eDP receiver is compliant with the DisplayPort Specification 1.2a and the Embedded DisplayPort Specification version 1.3. With internal HDCP key Integrated, the device support HDCP 1.4 specifications. In the device’s receiver block, which supports four 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 or 24-bit, and converted the input signal to HDMI output up to 1920x1080@120Hz or 3840x2160@30Hz. Leveraging the DisplayPort’s unique source/sink “Link Training” routine, the CH7525 is capable of instantly bring up the video display to the HDMI/DVI TV/Monitor when the initialization process is completed.

The CH7525 also supports up to 8-channel audio input from DP Rx and output from HDMI Tx with sample rate up to 192 KHz. Available audio bandwidth depends on the pixel clock frequency, the video format timing, and whether or not content protection re-synchronization is needed.

With sophisticated MCU and the On Chip Flash, CH7525 support auto-boot and EDID buffer. Leveraging the firmware auto-loaded from Flash, CH7525 can support DP input detection and determine to enter into Power saving mode automatically.
