It was designed to function as a dual 2-to-1 multiplexer to select between two USB high-speed differential data signals in portable battery powered products. It is offered in MSOP, TDFN and small µTQFN packages for use in MP3 players, cameras, PDAs, cell phones, and other personal media players. The part consists of four 4.4Ω high-speed (HSx) switches. These switches have high bandwidth and low capacitance to pass USB high-speed (480Mbps) differential data signals with minimal edge and phase distortion. They can also swing from 0V to 3.3V to pass USB full speed (12Mbps) differential data signals with minimal distortion. The device has an enable pin to open all switches and put the part in a low power down state. It can be used to facilitate proper bus disconnect and connection when switching between the USB sources. The ISL54222A was designed for MP3 players, cameras, cell phones, and other personal media player applications that have multiple high-speed or full-speed transceivers sections and need to multiplex between these USB sources to a single USB host (computer). A typical application block diagram of this functionality is shown on page 9. A detailed description of the HS switches is provided in the following section. High-Speed (HSx) Switches The HSx switches (HSD1-, HSD1+, HSD2-, HSD2+) are bi-directional switches that can pass 0V to 3.3V signals. When powered with a 1.8V supply, these switches have a nominal rON of 5.7Ω over the signal range of 0V to 400mV 9 USB HIGH-SPEED OR FULL-SPEED TRANSCEIVER #1 USB HIGH_SPEED OR FULL-SPEED TRANSCEIVER #2 PORTABLE MEDIA DEVICE with a rON flatness of 0.60Ω. The rON matching between the HSD1 and HSD2 switches over this signal range is only 0.072Ω, ensuring minimal impact by the switches to USB high-speed signal transitions. As the signal level increases, the rON switch resistance increases. With supply of 1.8V, the switch resistance with the signal level at the rail is nominally 12Ω. See Figures 7, 8, 9, 10, 11 and 12 in the “Typical Performance Curves” beginning on page 11. The HSx switches were specifically designed to pass USB 2.0 high-speed (480Mbps) differential signals in the range of 0V to 400mV. They have low capacitance (4.2pF) 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 13 in the “Typical Performance Curves” on page 12 for USB High-speed Eye Pattern taken with switches in the differential signal paths. The HSx 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 Figures 14 and 15 in the “Typical Performance Curves” on page 13 for USB Full-speed Eye Patterns taken with switches in the differential signal paths. The maximum normal operating signal range for the HSx switches is from 0V to 3.3V. The signal voltage should not be allowed to exceed 3.3V or go below ground by more than -0.3V for normal operation. However, in the event that the USB 5.25V VBUS voltage gets shorted to one or both of the D-/D+ pins, the ISL54222A has special fault protection circuitry to prevent damage to the ISL54222A part. The fault circuitry allows the signal pins (D-, D+, HSD1-, HSD1+, HSD2-, HSD2+) to be driven up to 5.5V while the VDD supply voltage is in the range of 0V to 3.3V. In this condition, the part draws < 300µA of IDD current and 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 FN6902.1 February 4, 2010 ISL54222A in the range of 1.8V to 3.3V, the fault voltage will pass through to the output of an active switch channel. During the fault condition normal operation is not guaranteed until the fault is removed. See the following “USB 2.0 VBUS Short Requirements” on page 10. The HS1 channel switches are active (turned ON) whenever the SEL voltage is logic”0”(Low) and the OE voltage is logic”0”(Low). The HS2 channel switches are active (turned ON) whenever the SEL voltage is logic “1” (High) and the OE voltage is logic “0” (Low). ISL54222A Operation The following will discuss using the ISL54222A shown in the “Application Block Diagram” on page 9. POWER The power supply connected at the VDD pin provides the DC bias voltage required by the ISL54222A part for proper operation. The ISL54222A can be operated with a VDD voltage in the range of 1.8V to 3.3V. A 0.01µF or 0.1µF 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. LOGIC CONTROL The state of the ISL54222A device is determined by the voltage at the SEL pin and the OE pin. SEL is only active when the OE pin is logic “0” (Low). Refer to “Truth Table” on page 2. The ISL54222A logic pins are designed to minimize current consumption when the logic control voltage is lower than the VDD supply voltage. With VDD = 3.3V and logic pins at 1.4V, the part typically draws only 6.6µA. With VDD = 1.8V and logic pins at 1.4V, the part typically draws only 0.2µA. Driving the logic pins to the VDD supply rail minimizes power consumption. The logic pins must be driven High or Low and must not float. LOGIC CONTROL VOLTAGE LEVELS With VDD supply voltage in the range of 1.8V to 3.3V the logic levels are: OE = Logic “0” (Low) when VOE ≤ 0.5V OE = Logic “1” (High) when VOE ≥ 1.4V SEL = Logic “0” (Low) when VSEL ≤ 0.5V SEL = Logic “1” (High) when VSEL ≥ 1.4V HSD1 USB CHANNEL If the SEL pin = Logic “0” and the OE pin = Logic “0”, high-speed Channel 1 will be ON. The HSD1- and HSD1+ switches are ON and the HSD2- and HSD2+ switches are OFF (high impedance). When a computer or USB hub is plugged into the common USB connector and Channel 1 is active, a link will be established between the USB 1 transceiver section of the media player and the computer. The device 10 transceiver 1 will be able to transmit and receive data from the computer. HSD2 USB Channel If the SEL pin = Logic “1” and the OE pin = Logic “0”, high-speed Channel 2 will be ON. The HSD2- and HSD2+ switches are ON and the HSD1- and HSD1+ switches are OFF (high impedance). When a USB cable from a computer or USB hub is connected at the common USB connector and the part has Channel 2 active, a link will be established between the USB 2 transceiver section of the media player and the computer. The device transceiver 2 will be able to transmit and receive data from the computer. ALL SWITCHES OFF/LOW POWER MODE If the SEL pin = Logic “0” or Logic “1” and the OE pin = Logic “1”, all of the switches will turn OFF (high impedance) and the part will be put in a low power mode. In this mode the part draws only 1.5µA (max) of current across the operating temperature range. The all OFF state can be used to switch between the two USB sections of the media player. When disconnecting from one USB device to the other USB device, you can momentarily put the ISL54222A switch in the “all off” state in order to get the computer to disconnect from the one device so it can properly connect to the other USB device when that channel is turned ON. USB 2.0 VBUS Short Requirements The USB 2.0 specification in chapter 7, section 7.1.1 states a USB device must be able to withstand a VBUS short to the D+ or D- signal lines when the device is either powered off or powered on for at least 24 hours. The ISL54222A part has special fault protection circuitry to meet these short circuit requirements. The fault protection circuitry allows the signal pins (D-, D+, HSD1-, HSD1+, HSD2-, HSD2+) to be driven up to 5.5V while the VDD supply voltage is in the range of 0V to 3.3V. In this overvoltage condition, the part draws < 300µA of IDD current and causes no stress or damage to the IC. In addition, when VDD is at 0V (ground), all switches are OFF and the shorted VBUS voltage is isolated from the other side of the switch. When VDD is in the range of 1.8V to 3.3V, the shorted VBUS voltage will pass through to the output of an active (turned ON) switch channel but not through a turned OFF channel. Any components connected on the active channel must be able to withstand the overvoltage condition. Note: During the fault condition, normal operation of the USB channel is not guaranteed until the fault condition is removed.
