一.产品概述PYP嘉泰姆

  The CXAS4243 is a Low-Power, Two-Port, High-Speed, USB2.0 (480Mbps) PYP嘉泰姆

double –pole double-throw (DPDT) Analog Switch featuring an On-Resistance PYP嘉泰姆

of 4.5 ohm at VCC=3V and a Low On Capacitance 3.7pf Typical. The CXAS4243 is compatible with the requirements of USB2.0 and the wide bandwidth needed PYP嘉泰姆

to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to channel crosstalk also minimizes interference. Break-before-make function for both parts eliminates signal disruption during switching from preventing both switches being enabled simultaneously. PYP嘉泰姆

The CXAS4243 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (VCC=0), which allows the device to withstand PYP嘉泰姆

an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the Sel pin is lower than the supply voltage (VCC). This feature is especially valuable to ultra-portable applications, such as cell phones, allowing for direct interface with the general purpose I/Os PYP嘉泰姆

of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers  PYP嘉泰姆
