FIGURE 6A. MEASUREMENT POINTS FIGURE 6B. TEST CIRCUIT FIGURE 6. SKEW TEST Detailed Description Power Supply Considerations The ISL54230 is a multiprotocol switch containing eight switches configured as a Quad DPDT. Each DPDT switch is independently controlled by a logic pin. The ISL54230 has four switches that are compliant in passing USB2.0 signals and four switches with low rON that can be used to pass analog or digital signals such as audio or UART. It is offered in a 36 ball WLCSP or a 32 Ld 5mmx5mm TQFN package for applications which require small package size such as cellphones and PDAs. The power supply connected to the VDD and GND pins provides the DC bias voltage necessary to operate the IC. The ISL54230 can be operated with a supply voltage in the range of +2.0V to +5.5V. For USB applications, the supply voltage should be in the range of +3.0V to +5.5V to ensure proper signal levels on the USB data lines. The ISL54230 contains four switches capable of passing USB2.0 Full-Speed and High-Speed signals with minimal distortion, two 1Ω switches and two 6Ω switches for analog/digital signals. The USB capable switches were designed with low capacitance and high bandwidth to pass USB HS signals (480Mbps) with minimal edge and phase distortion. The 1Ω switches are designed for passing low bandwidth signals (<8MHz) and are ideal for switching power lines since the low ON-resistance minimizes power dissipation. The 6Ω switches are designed to pass audio or data signals up to 100MHz while maintaining a low rON for good THD performance. In addition to the four independent logic control pins that control each DPDT switch, the ISL54230 contains two Output Enable (OE) logic pins that permits the IC to disable certain switches giving the user a high degree of flexibility in signal routing. Please see “OE Control Truth Table” on page 3 for an explanation of the OE pins. All logic pins on the ISL54230 are 1.8V logic compatible up to a +3.3V supply. 9 A decoupling capacitor in the range 0.01µF to 0.1µF should be connected to the VDD supply pin of the IC to filter out any power supply noise that may be present on the supply lines. The capacitor should be place as closed as possible to the VDD pin. Supply Sequencing and Power-On Reset Protection Proper power supply sequencing is necessary to protect the ISL54230 from operating in fault conditions. The ISL54230 integrates Power-On Reset (POR) circuitry that prevents the switches from turning ON until the supply voltage is at least +1.4V. The POR has a 100mV hysteresis built in that will turn the switches OFF when the supply has gone below +1.3V. This function prevents signals from the switch input being passed to the output when the device operating voltage has not reached appropriate levels yet, protecting the switch from fault conditions. The POR circuitry also protects the switch from operating in a fault condition should the power supply to the IC drop below the POR threshold. Thus, the recommended operational supply voltage is within +2.0V to +5.5V. Operating at supply voltages below +2.0V may still be functional but the noise margin between the POR threshold and supply voltage will be reduced. The device may FN6825.2 May 28, 2009 ISL54230 unexpectedly shut down if transient voltages trigger the POR. analog or digital signal routing such as audio, UART or Full-Speed USB. Overvoltage and Short Circuit Considerations The low ON-resistance of these switches are well suited for passing audio signals with good THD performance, even with low impedance loads such as 32Ω headphones (see Figure 24 for THD performance curves). The ISL54230 should be protected from overvoltage conditions. The IC contains ESD protection diodes that are back biased from the switch terminals to ground. Negative voltages on the switch terminals that are large enough to forward-bias these ESD protection diodes will result in a large current flowing from ground that may destroy these diodes. Thus, signals on the switch terminals should not swing below ground and cannot exceed the specified “Absolute Maximum Ratings” on page 5 for safe operation. The ISL54230 can have signals that go above the positive supply rail with no adverse effects up to +5.5V. The ESD protection circuitry permits the signal from going beyond the VDD supply (even with VDD = 0V) without inducing large leakage currents on the switch pins when the supply voltage is less than +5.5V. This feature complies with the USB 2.0 Specifications for short circuit protection in the event that the 5.25V VBUS line shorts to the USB signal lines. Note: When the supply voltage is above the POR threshold and a VBUS fault conditions occurs, the VBUS signal will be passed to the other side of the switch if the logic control pins are biased such that the switch is turned ON. USB Switches (COM2x and COM3x) The four USB FS and HS capable switches are bi-directional analog switches that can pass rail-to-rail signals with minimal distortion. With a 3.0V power supply, these switches have a nominal ON-resistance of 6Ω in the 0V to 400mV signal range. The low capacitance and high bandwidth of the switches makes them ideal for USB applications. They are specifically designed to pass both USB FS (12Mbps) and USB HS (480Mbps) differential signals while meeting the USB 2.0 signal quality eye diagrams (Figures 25 and 26). The USB switches are designed with integrated protection circuitry for fault conditions as defined in the USB 2.0 Specifications-Section 7.1.1. If a condition where VBUS (5.25V) is shorted to the D+ or D- pin this will not damage the device, even without power to the IC. 1Ω Switches (COM1A and COM4A) and 6Ω Switches (COM1B and COM4B) The two 1Ω switches are bi-directional analog switches that can pass rail-to-rail signals, making them well suited for analog or digital signal routing. The low ON-resistance of the switches makes them ideal for switching ON/OFF power supply lines for applications that interface with devices that require power (ie: SIM cards or flash memory devices). With a ON-resistance of 1Ω the power dissipation through the switch is minimal. The two 6Ω switches are bi-directional analog switches that can pass rail-to-rail signals, making them well suited for 10 Logic Control Pins The ISL54230 contains six logic control pins, IN1 through IN4 for independently controlling each DPDT switch and two OE enable pins. The logic control pins determine the state of the switches. Refer to the “Input Select” and “OE Control” Truth Tables on page 3. When the OEx control pins are logic LOW, only the switches on COM2x and COM3x are active and the switch state determined by IN2 and IN3 respectively. When the OEx control pins are logic HIGH, all switches are active and the switch state determined by the INx control pins. When the OEx control pins are in opposing logic states either COM1x and COM2x are active or COM3x and COM4x are active depending on what states OE1 and OE2 are at. The active switches are controlled by the respective INx control pin. This feature is useful for applications that interface the ISL54230 to Master/Slave devices or controlling two SIM cards in Dual SIM Card cellphones. The OEx control pins permit total deactivation of each half of the switch blocks to disable devices connected to those switches. LOGIC CONTROL VOLTAGE LEVELS OEx = Logic “0” (Low) when VOEx ≤ 0.5V OEx = Logic “1” (High) when VOEx ≥ 1.4V INx = Logic “0” (Low) when VINx ≤ 0.5V INx = Logic “1” (High) when VINx ≥ 1.4V The logic control pins are +1.8V CMOS logic compatible (0.45V VOLMAX and 1.35V VOHMIN) for supply voltages from +1.8V to +3.6V. over a supply range of 1.8V to 3.3V (see Figure 23). At 3.6V the VIL level is 0.5V maximum. This is still below the 1.8V CMOS guaranteed low output maximum level of 0.45V, but noise margin is reduced. At 3.6V the VIH level is 1.4V minimum. While this is above the 1.8V CMOS guaranteed high output minimum of 1.35V under most operating conditions the switch will recognize this as a valid logic high. The digital input stages draws a larger supply current whenever the digital input voltage is not at one of the supply rails. Driving the digital input signals from GND to V+ with a fast transition time minimizes power dissipation. The ISL54230 has been designed to minimize the supply current whenever the digital input voltage is not driven to the supply rails (0V to V+). For example driving the device with 1.8V logic high while operating with a 3.6V supply the device draws only 1µA of current.
