CXL 3 CONTROLLER IP

Logic Fruit Global Technologies Inc

Select

Logic Fruit's CXL 3 Controller IP is designed to support dual-mode operation, allowing dynamic selection between host and device modes. It connects to standard 64GT/s PHYs through the PIPE 6.x interface and supports high data rates across various link widths.The CXL 3 Controller IP is forward compatible with CXL 3.x and backward compatible with previous versions, offering flexible configurations needed for advanced systems. It supports multiple channels and configurable CXL degraded modes, ensuring seamless integration with CXL devices and enabling high-performance data transfer. Ideal for versatile system designs, it accommodates all three CXL device types to facilitate efficient connectivity and scalable architecture.
