USB 2.0 High-Speed x 2Channels/Stereo Audio Dual SP3T (Dual 3-to-1 Multiplexer)
The Intersil ISL54217 is a single supply dual SP3T analog switch that operates from a single supply in the range of 2.7V to 4.6V. It was designed to multiplex between audio stereo signals and two different USB 2.0 high speed differential data signals. The audio channels allow signal swings below ground, allowing the multiplexing of voice and data signals through a common headphone connector in Personal Media Players and other portable battery powered devices. The audio switch cells can pass 1V ground referenced audio signals with very low distortion (<0.03% THD+N when driving 5mW into 32 loads). The USB switch cells have very low ON-capacitance (8pF) and high bandwidth to pass USB high speed signals (480Mbps) with minimal edge and phase distortion. The ISL54217 is available in a tiny 12 Ld 2.2mmx1.4mm ultra thin QFN and a 12 Ld 3mmx3mm TQFN package. It operates over a temperature range of -40C to +85C.

Detailed Description
The ISL54217 device consists of dual SP3T (single pole/triple throw) analog switches. It operates from a single DC power supply in the range of 2.7V to 4.6V. It was designed to function as differential 3-to-1 multiplexer to select between two different USB differential data signals and audio L and R stereo signals. It comes in a tiny TQFN and TQFN packages for use in MP3 players, PDAs, cell phones, and other personal media players. 9
A device consists of two 2.3 audio switches and four 6.2 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 ISL54217 was specifically designed for MP3 players, personal media players and cellphone applications that need

to combine the stereo audio and USB data channels into a single shared connector, thereby saving space and component cost. The Typical application block diagram of this functionality is previously shown. The ISL54217 contains two logic control pins (C1 and C0) that determine the state of the device. The part has the following five states or modes of operation: All SWITCHES OFF; USB1; USB2; Audio; and Audio Mute. These states are discussed in detail in "Logic Control" on page 10. A detailed description of the various types of switches are provided in "Audio Switches" beginning on page 10. minimum edge and phase distortion to meet USB 2.0 signal quality specifications. See Figures 27 and 28 for High-speed Eye Pattern taken with switch in the signal path. These switches can also swing rail to rail and pass USB full-speed signals (12Mbps) with minimal distortion. See Figure 29 for Full-speed Eye Pattern taken with switch in the signal path. The maximum normal operating signal range for the USB switches is from -1V to VDD. The signal voltage at D- and D+ should not be allow to exceed the VDD voltage rail or go below ground by more than -1V for normal operation. However in the event that the USB 5.25V VBUS voltage were shorted to one or both of the COM pins, the ISL54217 has fault protection circuitry to prevent damage to the ISL54217 part. The fault circuitry allows the signal pins (COM-, COM+, 1D-, 1D+, 2D-, 2D+, L and R) to be driven up to 5.25V while the VDD supply voltage is in the range of 0V to 4.6V. This fault condition causes no stress to the IC. In addition, when VDD is at 0V (ground) all switches are OFF and the fault voltage is isolated from the other side of the switch. When VDD is in the range of 2.7V to 4.6V the fault voltage will pass through to the output of an active switch channel. Note: During the fault condition normal operation is not guaranteed until the fault condition is removed. The USB (1D+ and 1D-) switches are active (turned ON) whenever the C1 is logic "0" (Low) and C0 is logic "1" (High). The USB (2D+ and 2D-) switches are active (turned ON) whenever the C1 is logic "1" (High) and C0 is logic "0" (Low) provided the last state was not the Audio or Audio Mute state.
Audio Switches
The two audio switches (L, R) are 2.3 switches that can pass signals that swing below ground. Over a signal range of 1V (0.707Vrms) with VDD > 2.7V, these switches have an extremely low rON resistance variation. They can pass ground referenced audio signals with very low distortion (<0.05% THD+N) when delivering 15.6mW into a 32 headphone speaker load. See Figures 20, 21, 22, 23 and 24 THD+N performance curves. Crosstalk between the L and R audio switches over the frequency range of 20Hz to 20kHz when driving a 32 load is < -88dB. These switches have excellent off-isolation > 105dB over the audio band when connected to 32 loads and 77dB when connected to 20k loads (In Audio Mute mode). See Figures 25 and 26 in "Typical Performance Curves" section beginning on page 12. The audio drivers should be connected at the L and R side of the switch (pins 2 and 3) and the speaker loads should be connected at the COM side of the switch (pins 7 and 8). The switches have click and pop circuitry on the L and R side that is activated when the part comes out of Audio mode by taking the C1 and C0 logic pins low (All OFF mode). The ISL54217 should be put in this mode before powering down or powering up of the audio CODEC drivers. In this mode the audio, USB1, USB2 switches will be OPEN (OFF) and the audio click and pop circuitry will be ON. The high off-isolation of the audio switches along with the click and pop circuitry will isolate the transients generated during power-up and power down of the audio CODECs from getting through to the headphones thus eliminating click and pop noise in the headphones. See the "AC Coupled click and pop operation" on page 12. The audio switches are active (turned ON) whenever the C1 and C0 logic pins are logic "1" (High).
ISL54217 Operation
The discussion that follows will discuss using the ISL54217 in the "Block Diagram" on page 9. LOGIC CONTROL The state of the ISL54217 device is determined by the voltage at the C1 pin (pin 9) and the C0 pin (pin 10). The part has five states or modes of operation. The All SWITCHES OFF mode, USB1 mode, USB2 mode, Audio mode and Audio Mute mode. Refer to "Truth Table" on page 3 and "State Diagram" on page 2 of data sheet. The C1 pin and C0 pin are internally pulled low through 4M resistors to ground and can be tri-stated or left floating. The C1 pin and C0 pin can be driven with a voltage that is higher than the VDD supply voltage. They can be driven up to 5.25V with the VDD supply in the range of 2.7V to 4.6V. Driving the logic higher than the supply rail will cause the logic current to increase. With VDD = 2.7V and VLOGIC = 5.25V, ILOGIC current is approximately 5.5A.
USB Switches
The four USB switches (1D+, 1D-, 2D+, 2D-) are 6.2 bidirectional switches that were specifically designed to pass high-speed USB differential data signals in the range of 0V to 400mV. The switches have low capacitance and high bandwidth to pass USB high-speed signals (480Mbps) with 10

ISL54217
Logic Control Voltage Levels With VDD in the range of 2.7V to 3.6V the logic levels are: C1, C0 = Logic "0" (Low) when 0.5V or Floating. C1, C0 = Logic "1" (High) when 1.4V ALL SWITCHES OFF Mode If the C1 pin = Logic "0" and C0 pin = Logic "0" the part will be in the ALL SWITCHES OFF mode. In this mode the 2Dand 2D+ USB switches, the L and R audio switches and the 1D- and 1D+ USB switches will be OFF (high impedance). The audio click and pop shunt circuitry will be activated (ON) and the 1k COM shunt resistors will be disconnected (OFF). Before powering down or powering up of the audio CODECs drivers the ISL54217 should be put in the ALL SWITCHES OFF mode. In this mode transients present at the L and R signal pins due to the changing DC voltage of the audio drivers will not pass to the headphones, preventing clicks and pops in the headphones. See the "AC Coupled click and pop operation" on page 12. It is recommended that when transitioning from USB1 to USB2 or from USB2 to USB1 that you always pass through the All Switches OFF state. Audio Mode If the C1 pin = Logic "1" and C0 pin = Logic "1" the part will be in the Audio mode. In Audio mode the L (left) and R (right) 2.3 audio switches are ON. The 1D- and 1D+ 6.2 USB switches and 2D- and 2D+ 6.2 USB switches will be OFF (high impedance). The audio click and pop circuitry is de-activated. The 1k shunts on the COM side of the switch will be disconnected (OFF). When a headphone is plugged into the common connector, the controller will drive the C1 and C0 logic pins "High" putting the part in the audio mode. In the audio mode, the audio drivers of the player can drive the headphones and play music. USB1 Mode If the C1 pin = Logic "0" and C0 pin = Logic "1" the part will go into USB1 mode. In USB1 mode the 1D- and 1D+ 6.2 switches are ON. The L and R 2.3 audio switches and 2Dand 2D+ 6.2 USB switches will be OFF (high impedance). The audio L and R click and pop shunt circuitry will be activated and the 1k COM shunt resistors will be disconnected (OFF). When a USB cable from a computer or USB hub is connected at the common connector, the controller will route the incoming USB signal to USB transceiver section #1 by taking the C1 pin "Low" and the C0 pin "High" putting the ISL54217 part into the USB1 mode. In USB1 mode the computer or USB hub transceiver and the MP3 player or 11 cellphone USB transceiver #1 are connected and digital data will be able to be transmit back and forth. USB2 Mode If the C1 pin = Logic "1" and C0 pin = Logic "0" the part will be in the USB2 mode provided that the last state was not the Audio or Audio Mute state. In the USB2 mode the 2D- and 2D+ 6.2 USB switches will be ON and audio switches and the 1D- and 1D+ USB switches will be OFF (high impedance). The audio L and R click and pop shunt circuitry will be activated and the 1k COM shunt resistors will be disconnected (OFF). When a USB cable from a computer or USB hub is connected at the common connector, the controller will route the incoming USB signal to USB transceiver section #2 by taking the C1 pin "High" and the C0 pin "Low" putting the ISL54217 part into the USB2 mode. In USB2 mode the computer or USB hub transceiver and the MP3 player or cellphone USB transceiver #2 are connected and digital data will be able to be transmit back and forth. Audio MUTE Mode If the C1 pin = Logic "1" and C0 pin = Logic "0" the part will be in the Audio MUTE mode provided that the last state was the Audio state. In the audio MUTE mode the 2D- and 2D+ USB switches, the L and R audio switches and the 1D- and 1D+ USB switches will be OFF (high impedance). The audio click and pop shunt circuitry will be de-activated and the 1k COM shunt resistors will be connected (ON). Note: 1k COM shunt resistors are only ON when in Audio MUTE mode. The 1k shunts provide 77dB of off-isolation when driving 10k to 20k amplifier inputs. Logic Control Timing Between C1 and C0 The ISL54217 has a unique logic control architecture. The part has five different logic states but only two external logic control pins, C1 and C0. Refer to "State Diagram" on page 2 and "Truth Table" on page 3. The following state transitions require both C1 and C0 logic control bits to change their logic levels in unison: All OFF(C1 = 0, C0 = 0) -----> Audio (C1 = 1, C0 =1) Audio (C1 = 1, C0 = 1) -----> All OFF (C1 = 0, C0 = 0) Audio Mute (C1 = 1, C0 = 0) -----> USB1 (C1 = 0, C0 = 1) The delay time between transition of these bits must be < 100ns to ensure that you directly move between these states without momentarily transitioning to one of the other states. For example, if you are going from the "All OFF" state to the "Audio" state and C0 does not go high until 100ns after C1 went high you will momentarily transition to the "USB2" state.
FN6817.3 May 4, 2009
ISL54217
Any signals connected at the USB2 signal lines will momentarily get passed through to the COM outputs. Delay time between C1 and C0 must be < 100ns and should be controlled by logic control drivers with well behaved monotonic transitions from High to Low and Low to High and with typical logic family rise and fall times of 1ns to 6ns. POWER The power supply connected at VDD (pin 11) provides power to the ISL54217 part. Its voltage should be kept in the range of 2.7V to 4.6V. In a typical application VDD will be in the range of 2.7V to 4.3V and will be connected to the battery or LDO of the MP3 player or cellphone. A 0.01F or 0.1F decoupling capacitor should be connected from the VDD pin to ground to filter out any power supply noise from entering the part. The capacitor should be located as close to the VDD pin as possible. Before power-up and power-down of the ISL54217 part the C1 and C0 control pins should be driven to ground or tri-stated. This will put the switch in the ALL SWITCHES OFF state, which turns all switches OFF and activate the click and pop circuitry. This will minimize transients at the speaker loads during power-up and power-down of the ISL54217 device. See Figure 32 in the "Typical Performance Curves" section. AC COUPLED CLICK AND POP OPERATION Single supply audio drivers have their signal biased at a DC offset voltage, usually at 1/2 the DC supply voltage of the driver. As this DC bias voltage comes up or goes down during power-up or power-down of the driver, a transient can be coupled into the speaker load through the DC blocking capacitor (see the "Block Diagram" on page 9). When a driver is OFF and suddenly turned ON the rapidly changing DC bias voltage at the output of the driver will cause an equal voltage at the input side of the switch due to the fact that the voltage across the blocking capacitor cannot change instantly. If the switch is in the Audio mode or there is no low impedance path to discharge the blocking capacitor voltage, before turning the audio switch ON, a transient discharge will occur in the speaker, generating a click/pop noise. Proper elimination of a click/pop transient at the speaker loads while powering up or down of the audio drivers requires that the ISL54217 have its click/pop circuitry activated by putting the part in the ALL SWITCHES OFF mode. This allows the transients generated by the audio drivers to be discharged through the click and pop shunt circuitry. Once the driver DC bias has reached VDD/2 and the transient on the switch side of the DC blocking capacitor has been discharged to ground through the click/pop shunt circuitry, the audio switches can be turned ON and connected through to the speaker loads without generating any undesirable click/pop noise in the speakers. With a typical DC blocking capacitor of 220F and the click/pop shunt circuitry designed to have a resistance of 20 to 70, allowing a 100ms wait time to discharge the transient before placing the switch in the Audio mode will prevent the transient from getting through to the speaker load. See Figures 30 and 31 in the "Typical Performance Curves" section.
