FSUSB22 Low-Power, 2-Port, High-Speed USB 2.0 (480Mbps) Switch March 2008 FSUSB22 Low-Power, 2-Port, High-Speed USB 2.0 (480Mbps) Switch Features Description FSUSB22 is a low-power, high-bandwidth switch -40dB Off Isolation at 250MHz specially designed for applications switching high-speed -40dB Non-adjacent Channel Crosstalk at 250MHz USB 2.0 signals in handset and consumer applications such as cell phone, digital camera, and notebook with On Resistance: 4.5 Typical (RON) hubs or controllers of limited USB I/O. The wide -3dB Bandwidth: 750MHz bandwidth (750MHz) allows signals to pass with minimum edge and phase distortion. Superior channel- Low-Power Consumption: 1A Maximum to-channel crosstalk results in minimal interference. It is Control Input: TTL Compatible compatible with the USB2.0 Hi-Speed standard. Bi-directional Operation . USB High-Speed and Full-Speed Signaling Capability Applications Cell Phones, PDAs, Digital Cameras, Notebook Computers Ordering Information Operating Packing Part Number Temperature Package Method Range 16-Terminal Depopulated Quad Very-Thin Flat Pack No Leads Tape and FSUSB22BQX -40 to +85C (DQFN), JEDEC MO-241, 2.5 x 3.5mm Reel 16-Lead Quarter Size Outline Package (QSOP), JEDEC MO-137, FSUSB22QSC -40 to +85C Tube 0.150-inch Wide 16-Lead Quarter Size Outline Package (QSOP), JEDEC MO-137, Tape and FSUSB22QSCX -40 to +85C 0.150-inch Wide Reel 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC FSUSB22MTC -40 to +85C Tube MO-153, 4.4mm Wide 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC Tape and FSUSB22MTCX -40 to +85C Reel MO-153, 4.4mm Wide All packages are lead free per JEDEC: J-STD-020B standard. 2005Fairchild Semiconductor Corporation www.fairchildsemi.com FSUSB22 Rev. 1.0.3 FSUSB22 Low-Power, 2-Port, High-Speed USB 2.0 (480Mbps) Switch Logic Diagram Analog Symbol V S CC D- USB 1 16 Port D+ Docking Station 1B 2 15 /OE 1 D+ USB D- Port 1B 3 14 4B 2 1 Docking Connector 4B 1A 4 13 2 2B D+ 5 12 4A D+ 1 USB USB 2.0 D- Port D- Host D+ 2B 3B 6 11 2 1 FSUSB22 Controller D+ D- USB D- Port 3B 2A 7 10 2 8 9 Notebook Computer GND 3A Figure 1.
