USB2524 is the industry's first USB switching hub that combines a USB Hi-Speed hub and switching functionality in a single device. Equipped with two upstream ports and four downstream ports, USB2524 enables USB device sharing and switching between two USB hosts without "cable swapping". Requiring no more than standard USB hub driver support, the USB2524 appears as a 4-port USB hub to either USB host system and supports standard USB topology.
Device Sharing and Switching
- Per-port switching provides maximum device sharing functionality
- Flexible switching modes ease system design
- Programmable auto-switch mode enables unique applications
High Throughput
- MultiTRAK architecture provides dedicated TT for every downstream port
- Maximum USB full-speed data rate at 12 Mbps per port even under full load
- Aggregate 960 Mbps maximum data rate when both Hi-Speed hosts are active
Minimum Software Overhead
- Appears as a standard USB 2.0 hub controller on either host system
- Requires no more than standard USB hub-class driver support already native in most operating systems
- Standard USB connect and disconnect behavior as device switched from one host to the other
Ease of Integration
- Small 8x8 mm 56QFN package occupies minimum PCB space
- Flexible configuration options ease embedded system design
- USB-IF certified silicon building block ensures full USB compliance
Applications
USB2524 USB MultiSwitch hub may be used in a number of applications:
- Desktop PC drive-bays
- Mobile PC dock stations and port replicators
- All-in-one and photo printers
- LCD monitors
- KVM switches
- USB device sharing peripherals
- Set-top boxes
- DVD/HDD recorders and players
- Any USB dual-role host and device systems
