These devices are designed for USB 2.0 high-speed applications at 480Mbps. The MAX4899E/ MAX4899AE also handle all the requirements for USB low- and full-speed signaling. In the case of USB low/ full speed, these devices can function normally even if the supply voltage is 2.7V, even though the USB signal may be higher than the supply voltage. The MAX4899E is a dual 3:1 multiplexer, whereas the MAX4899AE is a dual 4:1 multiplexer. The MAX4899E/ MAX4899AE feature two digital inputs, C0 and C1, to control the analog signal path. Typical applications include switching a USB connector between USB and other operations such as serial communications, audio, and video. An enable input (EN) is provided to disable all channels and place the device into a high-impedance (off) state, as well as shutting off the charge pump for minimum power consumption. The MAX4899E/MAX4899AE feature an additional charge-pump enable input (QP) to disable the charge pump. The switches remain active at a lower analog signal range and higher RON. The MAX4899E/MAX4899AE operate from a 2.7V to 3.6V power-supply voltage and are current-limit protected against +5.5V shorts to COMA- and COMA+. Digital Control Inputs (C0, C1) The MAX4899E/MAX4899AE provide two digital control inputs (C 0 , C 1 ) to select the analog signal path between the COMA_ and USB__ channels. The truth tables for the MAX4899E/MAX4899AE are shown in the Functional Diagrams. Since the MAX4899E only has three USB__ channels, the code C1:C0 = 1:1 can be used to place all channels into a high-impedance state. This is particularly useful for eliminating the extra control line to the EN input that is normally used for disabling all channels. Driving C 0 and C 1 rail-to-rail minimizes power consumption. Enable Input (EN) The MAX4899E/MAX4899AE feature an enable input (EN) that when driven high places all channels into a high-impedance state, as an all-off feature. The internal charge pump is also disabled when EN is high, thus minimizing the quiescent supply current. For normal operation, drive EN low. Charge-Pump Enable Input (QP) The charge-pump input (QP) disables and enables the internal charge pump. Drive QP high to disable the charge pump and reduce the quiescent supply current. 10 With the charge pump disabled, the MAX4899E/ MAX4899AE still function normally; however, the analog signal range is reduced and the switch on-resistance (RON) is increased. The analog signal range with the charge pump disabled is 0V to 1.5V. For normal operation, drive QP low. Analog Signal Levels Signals applied to COMA+ are routed to the USB_+ terminals, and signals applied to COMA- are routed to the USB_- terminals. These multiplexers are bidirectional, allowing COMA_ and USB_ to be configured as either inputs or outputs. The D+ and D- notation in the Pin Description table is arbitrary and can be interchanged. For example, USB D+ signals can be applied to COMAand are routed to the USB_- terminals. Additionally, these multiplexers can be used for non-USB signals. COMA+ and COMA- are normally connected to outside circuitry and are ±15kV ESD protected. The MAX4899E is a dual 3:1 multiplexer, allowing COMA+ to be routed to one of three USB_+ channels, and COMA- to be routed to one of three USB_- channels. The MAX4899AE is a dual 4:1 multiplexer, allowing COMA+ to be routed to one of four USB_+ channels, and COMA- to be routed to one of four USB_- channels. Overvoltage Fault Protection The MAX4899E/MAX4899AE feature +5.5V fault protection to COM A + and COM A -. When a fault occurs between 4.5V to 5.5V, the switch automatically goes into a current-limiting mode that limits current to less than 2mA. Fault protection prevents these switches and downstream devices from being damaged due to shorts to the USB bus voltage rail. Applications Information USB Switching The MAX4899E/MAX4899AE analog multiplexers are fully compliant with the USB 2.0 specification. The low on-resistance and low on-capacitance of these multiplexers make them ideal for high-performance switching applications. The MAX4899E/MAX4899AE are ideal for routing USB data lines and for applications that require switching between different data types (see Figure 8). Board Layout High-speed switches require proper layout and design procedures for optimum performance. Keep designcontrolled impedance PC board traces as short as possible. Ensure that bypass capacitors are placed as close to the device as possible and use large ground planes where possible. ______________________________________________________________________________________ USB 2.0 High-Speed, Fault-Tolerant 3:1, 4:1 Multiplexers USB0+ VBUS USB0- USB1+ AUDIO HEADPHONE D+ COMA+ USB1- MAX4899AE DCOMA- USB2+ AUXILIARY INPUT USB2- GND USB3+ USB CONNECTOR USB3- SERIAL DATA LINK Figure 8. MAX4899AE Multiplexing Four Data Types RC 1MΩ CHARGE-CURRENTLIMIT RESISTOR As with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The COMA+ and COMA- lines have extra protection against static electricity. Maxim’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, tri-state output mode, and powered down. After an ESD event, Maxim’s E-versions keep working without latchup, whereas competing products can latch and must be powered down to remove latch-up. Human Body Model The MAX4899E/MAX4899AE COMA+ and COMA- pins are characterized for ±15kV ESD protection using the Human Body Model (MIL-STD-883, Method 3015). Figure 9a shows the Human Body Model and Figure 9b shows the current waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the device through a 1.5kΩ resistor.
