Low Voltage, Dual SPDT, USB/CVBS/ Audio Switches, with Negative Signal Capability
The Intersil ISL54207 dual SPDT (Single Pole/Double Throw) switches combine low distortion audio/video and accurate USB 2.0 high speed (480Mbps) data signal switching in the same low voltage device. When operated with a 2.7V to 3.6V single supply, these analog switches allow audio/video signal swings below-ground, allowing the use of a common USB and audio/video connector in digital cameras, camcorders and other portable battery powered Personal Media Player devices. The ISL54207 incorporates circuitry for detection of the USB VBUS voltage, which is used to switch between the audio/video and USB signal sources in the portable device. The part has a control pin to open all the switches and put the part in a low power down state. The ISL54207 is available in a small 10 Ld 2.1mm x 1.6mm ultra-thin TQFN package and a 10Ld 3mm x 3mm TDFN package. It operates over a temperature range of -40 to +85C.

Detailed Description
The ISL54207 device is a dual single pole/double throw (SPDT) analog switch device that operates from a single DC power supply in the range of 2.7V to 3.6V. It was designed to function as a dual 2 to 1 multiplexer to select between USB differential data signals and mono audio/composite video baseband signals (CVBS). It comes in tiny TQFN and TDFN packages for use in cameras, camcorders, video MP3 players, PDAs, cell phones, and other personal media players. The part consists of two 3 audio/video switches and two 5 USB switches. The audio/video switches can accept signals that swing below ground. They were designed to pass ground reference audio or dc restored with synch composite video signals with minimal distortion. The USB switches were designed to pass high-speed USB differential data signals with minimal edge and phase distortion. The ISL54207 was specifically designed for digital cameras, camcorders, MP3 players, cell phones and other personal media player applications that need to combine the audio/video jacks and the USB data connector into a single shared connector, thereby saving space and component cost. A typical application block diagram of this functionality is shown above. The ISL54207 incorporates circuitry for the detection of the USB VBUS voltage, which is used to switch between the audio/video drivers and USB transceiver of the media player. The ISL54207 contains a logic control pin (CTRL) that when driven Low while VBUS is Low, opens all switches and puts the part into a low power state, drawing typically 1nA of IDD current. A detailed description of the two types of switches is provided in the following sections. The USB transmission and audio/video playback are intended to be mutually exclusive operations. 8
NC1 and NC2 Audio/Video Switches
The two NC (normally closed) audio/video switches (NC1, NC2) are 3 switches that can pass signals that swing below ground by as much as 1.5V. They were designed to pass ground reference audio signals and DC restored composite base-band signals (CVBS), including negative synchronizing pulse with minimal insertion loss and very low distortion and degradation. The -3dB bandwidth into 75 is 338MHz (Figure 17). Crosstalk between NC1 and NC2 @ 4MHz is -78dB (Figure 16), which allows composite video to be routed through one switch and mono-audio through the other switch with little interference. The recommended maximum signal range is from -1.5V to 1.5V. You can apply positive signals greater than 1.5V but the rON resistance of the switch increases rapidly above 1.5V. The signal should not be allowed to exceed the VDD rail or swing more negative than -1.5V. Over a signal range of 1V (0.707Vrms) with VDD > 2.7V, these switches have an extremely low rON resistance variation. They can pass a ground referenced audio signal with very low distortion (<0.06% THD+N) when delivering 15.6mW into a 32 headphone speaker load. See Figures 10, 11, 12, and 13 THD+N performance curves. Figure 8 and 9 shows the vector scope plots of a standard NTSC color bar signal at both the input (Figure 8) and output (Figure 9) of the ISL54207. The plots show that except for a little attenuation due to switch rON and test fixture cabling, there is virtually no degradation of the video waveform through the switch.

NO1 and NO2 USB Switches
The two NO (normally open) USB switches (NO1, NO2) are 5 bidirectional switches that are designed to pass high-speed USB differential signals in the range of 0V to 400mV. The switches have low capacitance and high bandwidth to pass USB high-speed signals (480Mbps) with minimum edge and phase distortion to meet USB 2.0 signal quality specifications. See Figure 14 for High-speed Eye Pattern taken with switch in the signal path. The maximum signal range for the USB switches is from -1.5V to VDD. The signal voltage at NO1 and NO2 should not be allowed to exceed the VDD voltage rail or go below ground by more than -1.5V. The NO switches are active (turned ON) whenever the VBUS voltage is to VDD + 0.8V. VBUS is internally pulled low, so when VBUS is floating, the USB switches are OFF.
FIGURE 8. VECTOR-SCOPE PLOT BEFORE SWITCH
Note: Whenever the NO switches are ON, the audio and video drivers need to be at AC or DC ground or floating to keep from interfering with the data transmission.
ISL54207 Operation
The discussion that follows will discuss using the ISL54207 in the typical application shown in the block diagram on page 8. LOGIC CONTROL The state of the ISL54207 device is determined by the voltage at the VBUS pin (pin 2) and the CTRL pin (pin 10). Refer to truth-table on page 2 of the data sheet. The VBUS pin and CTRL pin are internally pulled low through 4M resistors to ground and can be left floating. The CTRL control pin is only active when VBUS is logic "0". Logic control voltage levels: VBUS = Logic "0" (Low) when VBUS VDD + 0.2V or Floating. VBUS = Logic "1" (High) when VBUS VDD + 0.8V CTRL = Logic "0" (Low) when 0.5V or floating. CTRL = Logic "1" (High) when 1.4V Audio/Video Mode If the VBUS pin = Logic "0" and CTRL pin = Logic "1," the part will be in the Audio/Video mode. In Audio/Video mode the NC1 and NC2 3 audio/video switches are ON and the NO1 and NO2 5 USB switches are OFF (high impedance). In a typical application, VDD will be in the range of 2.7V to 3.6V and will be connected to the battery or LDO of the media player. When a audio/video jack is plugged into the common connector, nothing gets connected at the VBUS pin (it is floating) and as long as the CTRL = Logic "1," the ISL54207 part remains in the audio/video mode and the media player audio and video drivers can drive the speaker and video display.
FIGURE 9. VECTOR-SCOPE PLOT AFTER SWITCH
Figure 18 shows the differential gain (DG) and differential phase (DP) plots at the output of the switch using an actual NTSC composite video signal and a VM700A Video Measurement Test Set. DG = 0.28% and DP = 0.04. These NC switches are uni-directional switches. The audio/video sources should be connected at the NC side of the switch (pins 7 and 8) and the speaker load and video receiver should be connected at the COM side of the switch (pins 3 and 4). The NC switches are active (turned ON) whenever the VBUS voltage is to VDD + 0.2V or floating and the CTRL voltage to 1.4V. Note: Whenever the NC switches are ON the USB transceivers need to be in the high impedance state or static high or low state.

ISL54207
USB Mode If the VBUS pin = Logic "1" and CTRL pin = Logic "0" or Logic "1," the part will go into USB mode. In USB mode, the NO1 and NO2 5 switches are ON and the NC1 and NC2 3 audio switches are OFF (high impedance). When a USB cable from a computer or USB hub is connected at the common connector, the voltage at the VBUS pin will be driven to be in the range of 4.4V to 5.25V. The ISL54207 part will go into the USB mode. In USB mode, the computer or USB hub transceiver and the media player USB transceiver are connected and digital data will be able to be transmitted back and forth. When the USB cable is disconnected, the ISL54207 automatically turns the NO1 and NO2 switches OFF. Low Power Mode If the VBUS pin = Logic "0" and CTRL pin = Logic "0," the part will be in the Low Power mode. In the Low Power mode, the NCx switches and the NOx switches are OFF (high impedance). In this state, the device draws typically 1nA of current. EXTERNAL VBUS SERIES RESISTOR The ISL54207 contains a clamp circuit between VBUS and VDD. Whenever the VBUS voltage is greater than the VDD voltage by more than 2.55V, current will flow through this clamp circuitry into the VDD power supply bus. During normal USB operation, VDD is in the range of 2.7V to 3.6V and VBUS is in the range of 4.4V to 5.25V. The clamp circuit is not active and no current will flow through the clamp into the VDD supply. In a USB application, the situation can exist where the VBUS voltage from the computer could be applied at the VBUS pin before the VDD voltage is up to its normal operating voltage range and current will flow through the clamp into the VDD power supply bus. This current could be quite high when VDD is OFF or at 0V and could potentially damage other components connected in the circuit. In the application circuit, a 22k resistor has been put in series with the VBUS pin to limit the current to a safe level during this situation. It is recommended that a current limiting resistor in the range of 10k to 50k be connected in series with the VBUS pin. It will have minimal impact on the logic level at the VBUS pin during normal USB operation and protect the circuit during the time VBUS is present before VDD is up to its normal operating voltage. Note: No external resistor is required in applications where VBUS will not exceed VDD by more than 2.55V. POWER The power supply connected at VDD (pin 1) provides power to the ISL54207 part. Its voltage should be kept in the range of 2.7V to 3.6V when used in a USB/Audio/Video application to ensure you get proper switching when the VBUS voltage is at its lower limit of 4.4V.
