MP3/USB 2.0 High Speed Switch with Negative Signal Handling and Low Power Shutdown ISL54209 The Intersil ISL54209 dual SPDT (Single Pole/Double Throw) switch combines low distortion audio and accurate USB 2.0 high speed data (480Mbps) signal switching in the same low voltage device. When operated with a 2.5V to 5.0V single supply, this analog switch allows audio signal swings below ground, allowing for the use of a common USB and audio headphone connector in Personal Media Players and other portable battery powered devices. The ISL54209 logic control pins are 1.8V compatible, which allows for control via a standard µcontroller. The ISL54209 has an audio enable control pin to open all switches and put the part in a low power state. In this state, the device draws typically 1nA of current. The ISL54209 is available in a small 10 Ld 1.8mm x 1.4mm or 2.1mmx 1.6mm ultra-thin µTQFN packages and a 10 Ld 3mmx3mm TDFN package. It operates over a temperature range of -40°C to +85°C.

It was designed to function as a dual 2 to 1 multiplexer to select between USB differential data signals and audio L and R stereo signals. It comes in tiny µTQFN and TDFN packages for use in MP3 players, PDAs, cellular phones and other personal media players. The part consists of two 2.5Ω audio switches and two 5Ω USB switches. The audio switches can accept signals that swing below ground. They were designed to pass audio left and right stereo signals, that are ground referenced, with minimal distortion. The USB switches were designed to pass high-speed USB differential data signals with minimal edge and phase distortion. The ISL54209 was specifically designed for MP3 players, personal media players and cellular phone applications that need to combine the audio headphone jack and the USB data connector into a single shared connector, thereby saving space and component cost. “Typical Application Block Diagrams” on page 10 of this functionality are shown in Figures 8 and 9. The ISL54209 has a single logic control pin (IN) that selects between the audio switches and the USB switches. This pin can be driven Low or High to switch between the audio CODEC drivers and USB transceiver of the MP3 player or cellular phone. The ISL54209 also contains a logic control pin (CTRL) that when driven Low while IN is Low, opens all switches and puts the part into a low power state, drawing typically 1nA of IDD current. Detailed descriptions of the two types of switches are provided in the following sections. The audio switches are active (turned ON) whenever the IN voltage is ≤ 0.5V or floating and the CTRL voltage ≥ to 1.4V. USB Switches The two USB switches (D+, D-) are bidirectional switches that can pass rail-to-rail signals. When powered with a 3.3V supply, these switches have a nominal rON of 5Ω over the signal range of 0V to 400mV with a rON flatness of 0.45Ω. The rON matching between the D+ and Dswitches over this signal range is only 0.05Ω ensuring minimal impact by the switches to USB high speed signal transitions. As the signal level increases, the rON resistance increases. At a signal level of 3.3V, the switch resistance is nominally 25Ω. The USB switches were specifically designed to pass USB 2.0 high-speed (480Mbps) differential signals typically in the range of 0V to 400mV. They have low capacitance and high bandwidth to pass the USB high-speed signals with minimum edge and phase distortion to meet USB 2.0 high speed signal quality specifications. See Figure 12. The USB switches can also pass USB full-speed signals (12Mbps) with minimal distortion and meet all the USB requirements for USB 2.0 full-speed signaling. See Figure 13 for Full-speed Eye Pattern taken with switch in the signal path. The USB switches are active (turned ON) whenever the IN voltage is ≥ to 1.4V. COM+, COM-, 1D-, 1D+, 2D-, AND 2D+ ARE OVERVOLTAGE TOLERANT UP TO 5.5V AND DOWN TO -1.5V For normal operation, the signal range for the USB switches is from -1V to VDD. During normal operation, the signal voltage at D- and D+ should not be allowed to exceed the VDD voltage rail or go below ground by more than -1.0V. However, the ISL54209, with a VDD supply voltage in the range of 0V to 5.0V, can withstand an overvoltage of up to 5.5V or down to -1.5V applied at its COM pins (COM-, COM+) and/or USB signal pins (1D-, 1D+, 2D-, 2D+) without damage. In this overvoltage condition, the part draws 2.7V, these switches have an extremely low rON resistance variation. They can pass ground referenced audio signals with very low distortion (
