FSA221 — USB2.0 High-Speed and Audio Switches with Negative Signal Capability April 2007 FSA221 — USB2.0 High-Speed (480Mbps) and Audio Switches with Negative Signal Capability Features HS-USB: 4Ω Typical On Resistance HS-USB: 4.5pF Typical On Capacitance Audio: 3Ω Typical On Resistance -3db Bandwidth: > 720MHz Low Power Consumption Power-off Protection on Common D+/R, D-/L Ports Automatically Detects Vbus for Switch Path Selection Description The FSA221 is a Double-Pole, Double Throw (DPDT) multiplexer that combines a low-distortion audio and a USB2.0 High-Speed (HS) switch path. This configuration enables audio and USB data to share a common connector port. The architecture is designed to allow audio signals to swing below ground. This means a common USB and headphone jack can be used for personal media players and portable peripheral devices. Since USB2.0 is an industry standard for shared datapath in portable devices, the FSA221 also incorporates a Vbus detection capability. The FSA221 includes a power-off feature to minimize current consumption when Vbus is not present. This power-off circuitry is available for the common D+/R, D-/L ports only. Typical applications involve switching in portables and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers. Applications Cell Phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box IMPORTANT NOTE: For additional performance information, please contact analogswitch@fairchildsemi.com Ordering Information Part Number FSA221L10X FSA221MUX FSA221UMX Package Number Top Mark Pb-Free MAC010A MUA10A MLP010A GK FSA221 GL Yes Yes Yes Package Description 10-Lead MicroPak, JEDEC MO-255, 1.6 x 2.1mm 10-Lead MSOP JEDEC MO-187, 3.0 mm Wide 10-Lead Quad, Ultrathin MLP, 1.4 x 1.8mm Vbus ASel Vaudio D+ R D-L Figure 1. © 2006 Fairchild Semiconductor Corporation FSA221 Rev. 1.0.6 Switch Select Control Circuitry Rpd GND D+/R D-/L FSA221 Analog Symbol www.fairchildsemi.com FSA221 — USB2.0 High-Speed and Audio Switches with Negative Signal Capability © 2006 Fairchild Semiconductor Corporation FSA221 Rev. 1.0.6 www.fairchildsemi.com 18
