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 a small µTQFN package for use in MP3 players, cameras, PDAs, cell phones, and other personal media players. The device has an enable pin to open all switches. The part consists of four 5.5Ω 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 VDD to pass USB full speed (12Mbps) differential data signals with minimal distortion. The ISL54223 was designed for MP3 players, cameras, cell phones, and other personal media player applications that have multiple high-speed and/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 previously shown. 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 rail-to-rail signals. When powered with a 1.8V supply, these switches have a nominal rON of 5.5Ω over the signal range of 0V to 400mV with a rON flatness of 0.44Ω. 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, 7 the rON switch resistance increases. At signal level of 1.8V, the switch resistance is nominally 12Ω. See Figures 7, 8, 9, 10, 11 and 12 in the “Typical Performance Curves” beginning on page 9. 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 (6.5pF) 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 9 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 11 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 VDD. The signal voltage should not be allow to exceed the VDD voltage rail 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 ISL54223 has special fault protection circuitry to prevent damage to the ISL54223 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 in the range of 1.8V to 3.3V the fault voltage will pass through to FN6836.1 May 27, 2009 ISL54223 the output of an active switch channel. During the fault condition normal operation is not guaranteed until the fault is removed. See the “USB 2.0 VBUS Short Requirements” section below. established between the USB 1 transceiver section of the media player and the computer. The device will be able to transmit and receive data from the computer. The HS1 channel switches are active (turned ON) whenever the SEL voltage is logic”0” (Low) and the OE voltage is logic”0”(Low). 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). The HS2 channel switches are active (turned ON) whenever the SEL voltage is logic “1” (High) and the OE voltage is logic “0” (Low). ISL54223 Operation The following will discuss using the ISL54223 shown in the “Application Block Diagram” on page 7. POWER HSD2 USB Channel When a USB cable from a computer or USB hub is connected at the common USB connector and Channel 2 is active, a link will be established between the USB 2 transceiver section of the media player and the computer. The device will be able to transmit and receive data from the computer. All Switches OFF Mode The power supply connected at the VDD pin provides the DC bias voltage required by the ISL54223 part for proper operation. The ISL54223 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 ISL54223 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 the “Truth Table” on page 2. The ISL54223 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 35µA of IDD current. With VDD = 1.8V and logic pins at 1.4V the part typically draws only 6µA IDD current. Driving the logic pins to the VDD supply rail minimizes power consumption. The logic pins must be held 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). If the SEL pin = Logic “0” or Logic “1” and the OE pin = Logic “1”, all of the switches will turn OFF (high impedance). The “ALL OFF” state can be used to switch between the two USB sections of the media player. When switching from one USB transceiver section to the other USB transceiver section, you can momentarily put the ISL54222 switch in the “All OFF” state, in order to get the computer to disconnect from the current USB section, so it can properly connect to the other USB transceiver section 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 ISL54223 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/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. When a computer or USB hub is plugged into the common USB connector and Channel 1 is active, a link will be 8 FN6836.1 May 27, 2009 ISL54223 Typical Performance Curves TA = +25°C, Unless Otherwise Specified 14 6.0 ICOM = 40mA ICOM = 1mA 1.8V 12 5.5 1.8V 10 rON (Ω) rON (Ω) 5.0 2.7V 4.5 3.3V 4.0 8 3.0V 2.7V 6 3.3V 3.0V 3.5 3.0 4 2 0 0.1 0.2 VCOM (V) 0.3 0.4 0.5 1.0 1.5 2.0 VCOM (V) 3.0 3.3 16 8 V+ = 1.8V ICOM = 40mA V+ = 1.8V ICOM = 1mA 14 7 12 +85°C 6 +25°C 4 -40°C rON (Ω) 10 5 +85°C 8 +25°C 6 -40°C 4 3 2 2.5 FIGURE 8.
