It was designed to function as a dual 2-to-1 multiplexer to select between a USB high-speed transceiver and a USB full-speed transceiver in automotive applications. It is offered in a TDFN package for use in automotive Portable Media Player docking stations and Apple iPod type players. The device has an enable pin to open all switches. The part consists of two full speed (FSx) switches and two high speed (HSx) switches. The FSx switches can swing from 0V to VDD. They were designed to pass USB full speed (12Mbps) differential data signals with minimal distortion. The HSx switches have high bandwidth and low capacitance to pass USB high-speed (480Mbps) differential data signals with minimal edge and phase distortion. The ISL76120 was designed for automotive USB applications such as docking stations for Portable Media Players and other general purpose USB connections that have both high-speed and full-speed transceivers 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 8. A detailed description of the two types of switches are provided in the following sections. FSx Switches (FSD1, FSD2) The two FSx switches (FSD1, FSD2) are bidirectional switches that can pass rail-to-rail signals. They were specifically designed to pass USB full-speed (12Mbps) 8 differential signals and meet the USB 2.0 full-speed signal quality specifications. See Figure 8. The FSx switches can also pass USB high speed signals (480Mbps) but do not quite meet the USB 2.0 high speed signal quality eye diagram compliance requirement. The maximum signal range for the FSx switches is from -1V to VDD. The signal voltage should not be allowed to exceed the VDD voltage rail or go below ground by more than -1V. When operated with a 2.7V to 3.6V supply, the FSx switches are active (turned ON) whenever the IN logic control voltage is ≤0.5V and the EN logic voltage ≥1.4V. HSx Switches (HSD1, HSD2) The two HSx switches (HSD2, HSD1) are bi-directional switches that can pass rail-to-rail signals. The on-resistance is low and well matched between the HSD1 and HSD2 switches over the USB high speed signal range, ensuring minimal impact by the switches to USB high speed signal transitions. As the signal level increases, the rON switch resistance increases. The HSx switches were specifically designed to pass USB 2.0 high-speed (480Mbps) differential signals typically in the range of 0V to 400mV. They have low capacitance 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 Figures 9 and 10. 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 Figure 11. FN6711.1 May 29, 2008 ISL76120 The maximum signal range for the HSx switches is from -1V to VDD. The signal voltage should not be allow to exceed the VDD voltage rail or go below ground by more than -1V. The HSx switches are active (turned ON) whenever the IN voltage is ≥1.4V and the EN logic voltage ≥1.4V when operated with a 2.7V to 3.6V supply. ISL76120 Operation The discussion that follows will discuss using the ISL76120 in the typical application shown in the“Application Block Diagram” on page 8. POWER The power supply connected at the VDD (pin 1) provides the DC bias voltage required by the ISL76120 part for proper operation. The ISL76120 can be operated with a VDD voltage in the range of 2.7V to 5.5V. When used in a USB application, the VDD voltage should be kept in the range of 3.0V to 5.5V to ensure you get the proper signal levels for good signal quality. 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 Full-speed Mode If the IN pin = Logic “0” and the EN pin = Logic “1”, the part will be in the full-speed mode. In this mode, the FSD1 and FSD2 switches are ON and the HSD1 and HSD2 switches are OFF (high impedance). In a typical application, VDD will be in the range of 2.8V to 3.6V and will be connected to the battery or LDO of the portable media device. When a computer or USB hub is plugged into the common USB connector and the part is in the full-speed mode, a link will be established between the full-speed driver section of the media player and the computer. The device will be able to transmit and receive data from the computer at a data rate of 12Mbps. High-speed Mode If the IN pin = Logic “1” and the EN pin = Logic “1”, the part will go into high-speed mode. In high-speed mode, the HSD1 and HSD2 switches are ON and the FSD1 and FSD2 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 is in the high-speed mode, a link will be established between the high-speed driver section of the media player and the computer. The device will be able to transmit and receive data from the computer at a data rate of 480Mbps. All Switches OFF Mode The state of the ISL76120 device is determined by the voltage at the IN pin (pin 2) and the EN pin (pin 10). IN is only active when the EN pin is logic “1” (High). Refer to the “Truth Table” on page 2. The EN pin is internally pulled low through a 4MΩ resistor to ground. For logic “0” (Low) it can be driven low or allowed to Float. The IN pin must be driven low or high and cannot be left floating. Logic control voltage levels: If the IN pin = Logic “0” or Logic “1” and the EN pin = Logic “0”, 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 disconnecting from one USB device to the other USB device, you can momentarily put the ISL76120 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. EN = Logic “0” (Low) when VEN ≤0.5V or Floating. EN = Logic “1” (High) when VEN ≥1.4V IN = Logic “0” (Low) when VIN ≤0.5V. IN = Logic “1” (High) when VIN ≥1.4V 9 FN6711.1 May 29, 2008 ISL76120 Typical Performance Curves TA = +25°C, Unless Otherwise Specified VDD = 3.3V FIGURE 8.
