DATASHEET ISL76120 FN6711 Rev 3.00 Automotive Grade USB 2.0 High/Full Speed Multiplexer January 9, 2015 The Intersil ISL76120 dual 2:1 multiplexer IC is a single supply Features part that can operate from a single 2.7V to 5.5V supply. It High speed (480Mbps) and full speed (12Mbps) signaling contains two SPDT (Single Pole/Double Throw) switches capability per USB 2.0 configured as a DPDT. The part was designed for switching between USB high-speed and USB full-speed sources in portable 1.8V logic compatible (2.7V to +3.6V supply) battery powered products. Enable pin to open all switches, simplifies multiple USB The normally-closed (NC) FSx switches can swing rail-to-rail and client management were specifically designed to pass USB full speed data signals -3dB frequency (12Mbps) that range from 0V to 3.6V. The normally-open (NO) - HSx switches 880MHz HSx switches have high bandwidth and low capacitance and - FSx switches 550MHz were specifically designed to pass USB high speed data signals (480Mbps) with minimal distortion. Crosstalk at 1MHz -70dB The part can be used in a variety of automotive entertainment Off-isolation at 100kHz -98dB and infotainment applications where consumer USB devices Single supply operation (V ) . 2.7V to 5.5V DD such as Portable Media Players (PMPs) are to be connected to Available in TDFN package embedded systems. The product allows switching between a high-speed transceiver and a full-speed transceiver while Robust ESD rating > 8.5kV HBM connected to a single USB host. Additionally, the part can be Ultra-low operating current . 60nA used for charge control of PMPs. -40C to +105C Operation The digital logic inputs are 1.8V logic compatible when operated AEC-Q100 qualified component with a 2.7V to 3.6V supply. The part has an enable pin to open all switches. It can be used to facilitate proper bus disconnect Pb-Free (RoHS Compliant) and connection when switching between the USB sources. Applications The ISL76120 is available in a 10 Ld 3mmx3mm TDFN Automotive package. It operates across a temperature range of -40C to +105C. -USB docks - MP3 and PMP player attach kits - Infotainment systems After market automotive options 3.3V CONTROLLER V DD ISL76120 EN IN LOGIC CIRCUITRY VBUS USB 4M HIGH-SPEED HSD1 D- TRANSCEIVER HSD2 COMD1 USB D+ FSD1 FULL-SPEED COMD2 TRANSCEIVER FSD2 GND GND PORTABLE MEDIA DEVICE FIGURE 1.
