CL2440

RF Transceiver ICS Overview

The CL2440 is a highly integrated, single-chip solution designed for 5GHz Wi-Fi applications, implementing full IEEE 802.11ac Wave 2 functionality. It features a 4x4 MIMO architecture with an integrated RF, baseband, and MAC, alongside a powerful CPU, memories, and accelerators to maximize host offloading. The chip supports novel DSP-based PHY architecture for flexible SDR capabilities. Key technical specifications include support for 20MHz, 40MHz, 80MHz, and 160MHz channel bandwidths, up to 256-QAM modulation (MCS 8, 9), and explicit/implicit beamforming. It complies with IEEE 802.11a/n standards and includes advanced security protocols such as WPA2, AES, and TKIP.

RF Transceiver ICS Procurement Notes

Verify the specific ordering suffix and package variant against the official Renesas Electronics datasheet before procurement. Ensure compatibility with the target system's PCIe interface version, as the device is backwards compatible with v1.1 but primarily designed for v2.0. Confirm that the application environment supports the required 5GHz frequency band and regulatory compliance for beamforming features. Cross-reference the part number with current distributor catalogs to ensure availability of the correct revision level.

RF Transceiver ICS Selection Notes

Select the CL2440 when a compact, low-power solution is required for high-throughput 5GHz Wi-Fi environments. Its integrated design eliminates the need for external memories, reducing board space and complexity. Choose this component for applications demanding MU-MIMO capabilities and wide channel bandwidth support up to 160MHz. It is suitable for designs prioritizing thermal efficiency and cost-effectiveness without compromising on 802.11ac Wave 2 performance standards.
