GSV2125D is a 4K60HZ domestic audio and video conversion chip developed by Cornerstone Coollink, which can replace LT6711 and CS5801 chips, support HDMI to DP, and use applications such as portable screens, docking stations, mobile systems and embedded applications.

Gscoolink GSV2125D is a high-performance, low-power HDMI 2.0 to DP 1.4 converter. By integrating an enhanced microcontroller, GSV2125D created a cost-effective solution that provided a time-to-market advantage. The DP transmitter supports up to 32.4Gbps (HBR3, 4 lanes) and the HDMI receiver supports up to 18Gbps (TMDS, 6G/3 lanes). GSV2125D's superior architecture uses the QFN64 to provide an economical, smaller footprint solution for low-power embedded applications.

HDCP 1.4 and HDCP 2.2/2.3 are implemented in the GSV2125D for their DP and HDMI ports. Supports color space conversion, 420-444/422 conversion, deinterlacer, and downscaler for flexible video processing. GSV2125D supports audio extraction of HDMI Rx for audio processing.

The GSV2125D operates over a temperature range of -20ºC to 85ºC within 8kV HBM tolerances and is manufactured in automotive qualified processes.

The internal video generator can be used to generate any uncompressed video timing defined in the DP HBR3 bandwidth, such as 4K@60Hz, 4K@30Hz, 480i@60Hz.
