Product Overview: RK621 Key Specifications
The RK621 is a highly integrated video bridging SoC. It is not merely a simple signal converter but also features a built-in ARM processor and ISP, enabling it to independently handle image capture, processing, encoding, and display output, thereby greatly simplifying system design.
RK621 Detailed Specifications
Video Input Interface • Compatible with HDMI 1.4/HDMI 2.0, supports HDCP 1.4
Video Output Interface • MIPI DSI: Supports 1080p@60fps
• MIPI CSI: Supports 4K@30fps
• LVDS: Supports 720p@60fps
Audio Interfaces and Processing • Supports HDMI RX I2S interface, maximum sampling rate 192 kHz, stereo
• Supports I/O I2S
RK621 Key Features:
All-in-One Video Bridging: Seamlessly addresses the challenge of converting MIPI/LVDS signals to HDMI/DP. A single chip enables the full “Sensor -> Processing -> Display/Storage” workflow, eliminating the need for external logic chips.
4K Ultra-HD Experience: Supports HDMI 2.0 output, perfectly compatible with 4K@60Hz displays, featuring high color accuracy and ultra-low latency to meet professional-grade imaging requirements.
Built-in ISP and Encoding: Unlike ordinary bridge chips, the RK621 features a built-in ISP that connects directly to the camera sensor for image optimization. It also supports H.265 encoding, making it suitable for video recording devices and significantly reducing BOM costs.
Cost-Effective Domestic Solution: As a mature, mass-produced chip from Rockchip, the RK621 offers stable supply, high cost-effectiveness, a comprehensive SDK, and reference designs, enabling a short development cycle.
RK621 Core Application Areas
The RK621 supplied by Mingjiada Electronics is widely used in the following cutting-edge industries:
