Audio/USB 2.0 Wired-OR Switch with Click and Pop Reduction
ISL54409, ISL54410
The Intersil ISL54409 and ISL54410 are Dual SPST (Single Pole/Single Throw) switches that provides a very low distortion audio path for a stereo headphone and can be connected in a wired-OR configuration at the switch outputs with USB2.0 HS signals for Audio/USB signal multiplexing to a common connector. The audio switch path can be disabled to provide high signal isolation, preventing crosstalk between the audio codec and USB data signals. The ISL54409 and ISL54410 analog switches are negative swing capable with a single supply voltage and maintain excellent THD performance within a signal range of -1V to +1V. The switch terminals have low pin capacitance (4pF typical), minimizing impact to USB 2.0 High-Speed signals. The ISL54409 offers a Low Power Shutdown mode while the ISL54410 offers a High Off-Isolation mode. The ISL54410 contains active Audio Click and Pop Elimination circuitry for AC-coupled audio signals. The ISL54409 and ISL54410 are available in a 8 Ld TDFN (2mmx2mm) or a 10 Ld TQFN (1.8mmx1.4mm) package. They operate over a temperature range of -40 to +85C.

ISL54409, ISL54410
Detailed Description
The ISL54409, ISL54410 are +2.7 to +5.0V, Single Pole Single Throw (SPST) audio switches that are negative swing capable. The switch outputs (COM-, COM+) have low OFF capacitance (4pF) that is capable of multiplexing USB2.0 HS data and audio signals in a wired-OR configuration for common connector applications (see "Application Block Diagrams" on page 2). The ISL54409 features a low power shutdown mode while the ISL54410 features audio Click and Pop Elimination circuitry. The ISL54409, ISL54410 are offered in a 8 Ld 2mmx2mm TDFN or 10 Ld 1.4x1.8mm TQFN packages.
Exceeding VDD by putting the 5V VBUS signal to the IN pin will forward bias the ESD diode on the IN pin, which will draw excessive diode current and result in a damaged pin on the device. To prevent damage to the IN pin it is recommended to place a current limiting series resistor or use a voltage divider to bring the voltage at the IN pin below VDD. A 10k series resistor will reduce current significantly to prevent possible damage to the IN pin. For further protection, a voltage divider with RT = 10k will reduce the IN voltage below VDD with no impact on logic threshold voltages (see Figure 5).

Power Supply Considerations
The ISL54409, ISL54410 operates on a +2.7V to +5.0V power supply. A 0.1F local decoupling capacitor placed as closed as possible from the VDD pin to GND is highly recommended for stable operation.

Audio Switches
The ISL54409, ISL54410 switches are designed to have low THD+N from a signal range of -1V to +1V for audio applications (See Figures 8 through 11). The ON-resistance of the audio switches have a typical resistance of 2.6. The analog signal range of the audio switches are capable beyond -1V to +1V however, the ON-resistance of the switches increases beyond it. The THD+N performance deteriorates beyond a signal range of -1V to +1V.
FIGURE 5. USB VBUS HOT PLUG PROTECTION
Low Power Shutdown/Click and Pop Mode
When the CTRL and IN pins are at logic "0", the ISL54409 and ISL54410 enter into a disabled mode of operation. In the disabled mode of operation, both switches are turned OFF. For the ISL54409, the disabled mode is Low Power Shutdown. The device is brought to a low powered state and the Icc current is significantly reduced. *Note: When placed in the Low Power Shutdown state, the internal charge pumps that generate the negative supply rails for negative signal swing capability are turned off to reduce power consumption. With the internal negative supply rail disabled the ISL54409 will have poor isolation and crosstalk performance for negative signal swings on the switch terminals. Negative voltages will have a low impedance path to the other switch terminals. It is not recommended to operate the switch in Low Power Shutdown if the audio codec will remain active when transmitting USB data on the COMand COM+ pins. For the ISL54410, the disabled mode is Audio Click and Pop Elimination. The switch input pins LIN and RIN have their active Click and Pop circuitry enabled, which turns on a typical 40 shunt resistance from the switch input pin to GND. Some audio application requires DC biasing the audio codec above ground for full output signal swing. The audio signal must have the DC component removed with a blocking capacitor at the headphone load. This blocking capacitor is typically the source of audible click and pop transients when the audio codec powers up or down with the DC bias. The negative signal swing capability of the audio switch allows the DC blocking capacitor to be placed on input side of the switch, which allows the Click and Pop Elimination circuitry to discharge the DC blocking capacitor of any transient currents, eliminating audio clicks and pops.
FN6983.0 September 25, 2009
Audio/USB wired-OR Application
The ISL54409, ISL54410 allows the connection of an audio codec and USB Controller to a common connector. For audio mode of operation, the switch is closed to pass low distortion audio from the codec to a headphone. When the switch is open, USB2.0 HS data (480MBps) can be transmitted to a host controller with minimal signal degradation. Since the USB device is always connected to the COMand COM+ pins on the ISL54409, ISL54410, considerations must be taken to protect the USB Controller when passing audio signals through the switch. The USB2.0 specification requires the USB data line to sustain a signal of -1V without damage to the device. Audio signals from the codec may swing below 1V in some applications. Since the USB Controller is high impedance when not operating, exceeding -1V may cause high leakage currents or damage sensitive devices on the USB device. It is highly recommended to keep the audio signal range within -1V to +1V.
USB VBUS Hot Plug Operation
The ISL54409, ISL54410 allows the hot plug operation of the USB VBUS signal to operate the switch. This can be accomplished by connecting CTRL to VDD at all times. The VBUS signal from the USB Host is used to drive the IN logic pin. Note from the "Absolute Maximum Ratings" on page 5 that the IN pin must be kept below VDD.
