IDT™ HYBRID SWITCH WITH NEGATIVE SIGNAL HANDLING 2 IDTHS221P10 REV F 112108 IDTHS221P10 HYBRID SWITCH WITH NEGATIVE SIGNAL HANDLING HYBRID SWITCH Detailed Description switches that were designed to pass high-speed USB differential signals in the range of ±0V to 400 mV. 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 IDTHS221P10 device is a dual single pole/double throw (SPDT) 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 2 to 1 multiplexer to select between USB differential data signals and audio L and R stereo signals. It comes in tiny µMLP packages for use in cell phones, MP3 players, PDAs, and other personal media players. 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. The part consists of one hybrid dual 2Ω audio 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. Note: Whenever the USB switches are ON 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 IDTHS221P10 device is determined by the voltage at the SEL pin. Refer to truth table on page 2 of data sheet. These logic pins are 1.8 V logic compatible, and can be controlled by a standard µprocessor. The IDTHS221P10 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 SEL pin is internally pulled low through a 4MΩ resistor to ground and can be left floating or tri-stated by the µprocessor. The IDTHS221P10 has a SEL pin that select between the audio switches and the USB switches. This pin can be driven LOW or HIGH to switch between the audio inputs and USB data inputs. Logic control voltage levels: SEL = Logic “0” (Low) when <0.5 V SEL = Logic “1” (High) when >1.2 V Audio Switches The two audio switches (L, R) are 2Ω¸ 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. The audio switches are active (turned ON) whenever the SEL voltage to <0.5 V. Note: Whenever the audio switches are ON the USB transceivers need to be in the high impedance state or static high or low state. USB Switches The two USB switches (D+, D-) are 5Ω¸ bidirectional IDT™ HYBRID SWITCH WITH NEGATIVE SIGNAL HANDLING 3 IDTHS221P10 REV F 112108 IDTHS221P10 HYBRID SWITCH WITH NEGATIVE SIGNAL HANDLING HYBRID SWITCH Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the IDTHS221P10.
