AX68004 4-Port USB KVM Switch SoC

KVM (short for Keyboard, Video, and Mouse) is a hardware and software technology solution that allows you to control multiple computers from one set of peripherals. Compared with the legacy 4-port USB KVM switch using 12 chips (including one MCU, four USB device MCUs, one USB root hub, four EEPROMs and two bus switches), the AX68004 is a highly integrated single chip and low-cost solution ideally suitable for cable/desktop KVM Switch and KVM extender applications.

Compared with legacy chipset solution, the advantages of AX68004 single chip solution are: power management unit with deep sleep mode, manufacture driver for USB device in console is transparent to computers, same mouse sample rate on PC and device sides, integrating DDC (Display Data Channel) Emulation and EDID (Extended Display Identification Data), supporting four USB downstream ports in console, up to 7 USB devices in console (HID, Hub, MSC, Audio), and supporting touch screen, touch pad, and writing pad.
