The CL2442 is a powerful, highly integrated, 3x3 802.11ac 2.4GHz single chip implementing 802.11ac functionality including beamforming and four spatial streams. The CL2442 integrates both a CPU and memory to run more of the wireless LAN functions on-chip, with no need for costly external memories. Designed for fit, the CL2432 comes in a compact 88-pin QFN enabling a full 4x4 high performance 802.11ac interface in a standard full-sized min PCIe card with the lowest power consumption.
