HYBRID SWITCH WITH NEGATIVE SIGNAL HANDLING HYBRID SWITCH IDT™ HYBRID SWITCH WITH NEGATIVE SIGNAL HANDLING 3 IDTHS231P16 REV J 032708 Detailed Description The IDTHS231P16 device is a dual single pole/triple throw (SPTT) high performance switch device that can operate from a single DC power supply in the range of 1.7 V to 1.95 V. It was designed to function as a dual 3 to 1 multiplexer to select between USB differential data signals, UART signals and audio L and R stereo signals. It comes in tiny QFN packages for use in cell phones, MP3 players, PDAs, and other personal media players. The part consists of one hybrid dual 3Ω audio, 5Ω UART and 5Ω USB switches. The hybrid switch can accept audio signals that swing below ground and USB signals. They were designed to pass audio left and right stereo signals, and are ground referenced, with minimal distortion. The USB switches were designed to pass high-speed USB differential data signals with minimal edge and phase distortion. The IDTHS231P16 was specifically designed for cell phones and other personal media player applications that need to combine the audio headphone jack and the USB data connector into a single shared connector, thereby saving space and component cost. The IDTHS231P16 has SELx pins that select between the audio switches, UART and the USB switches. These pins can be driven LOW or HIGH to switch between the audio inputs and USB data inputs. Audio Switches The two audio switches (L, R) are typically 3Ω¸ switches that can pass signals that swing below ground by as much as 1.5 V. They were designed to pass ground reference stereo signals with minimal insertion loss and very low distortion. Crosstalk between the audio switches over the audio band is typically < -110dB. These audio switches are uni-directional switches. The audio drivers should be connected at the L and R side of the switch and the speaker loads should be connected at the COM side of the switch. Note: Whenever the audio switches are ON the USB and UART transceivers need to be in the high impedance state or static high or low state. USB/ UART Switches The two USB switches (D+, D-) and two UART switches (U+, U-) are typically 5Ω¸ bidirectional switches that were designed to pass high-speed USB differential signals in the range of ±0V to 400 mV, and UART signals. These switches have low capacitance and high bandwidth to pass USB high-speed signals (480 Mbps) with minimum edge and phase distortion to meet USB 2.0 high-speed signal quality specifications. The maximum signal range for the USB switches is from 0V to 3.6 V. The signal voltage at D- and D+ should not be allow to exceed the 3.6 voltage rail or go below ground. The USB switches are active (turned ON) whenever the SEL voltage is > 1.2 V. Note: Whenever the USB switches are ON, the UART or the audio drivers of the CODEC need to be at AC or DC ground or floating to keep from interfering with the data transmission. Logic Control The state of the IDTHS231P16 device is determined by the voltage at the SEL pins. Refer to truth table on page 2 of data sheet. These logic pins are 1.8 V logic compatible so that it can be controlled by a standard µprocessor. The SELx pins is internally pulled low through a 4MΩ resistor to ground and can be left floating or tri-stated by the µprocessor. Logic control voltage levels: SELx = Logic “0” (Low) when < 0.5 V SELx = Logic “1” (High) when >1.2 V
