FSA221 — USB2.0 High-Speed (480Mbps) and Audio Switches with Negative Signal Capability Features 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. 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 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. Automatically Detects Vbus for Switch Path Selection Applications Cell Phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box IMPORTANT NOTE: For additional performance information, please contact [email protected] Ordering Information Part Number Package Number Top Mark Pb-Free FSA221L10X MAC010A GK FSA221MUX MUA10A FSA221UMX MLP010A Package Description Yes 10-Lead MicroPak, JEDEC MO-255, 1.6 x 2.1mm FSA221 Yes 10-Lead MSOP JEDEC MO-187, 3.0 mm Wide GL Yes 10-Lead Quad, Ultrathin MLP, 1.4 x 1.8mm Vbus ASel Switch Select Control Circuitry Vaudio Rpd D+ GND D+/R R D-- D-/L L Figure 1. © 2006 Fairchild Semiconductor Corporation FSA221 Rev. 1.0.6 FSA221 Analog Symbol www.fairchildsemi.com FSA221 — USB2.0 High-Speed and Audio Switches with Negative Signal Capability April 2007 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
