| NLAS7222A 3.3 V, Wide Bandwidth, 2- to -1-Port (DPDT) Switch with Enable ON Semiconductor's NLAS7222A series of analog switch circuits are produced using the company's advanced sub-micron CMOS technology, achieving industry-leading performance. The NLAS7222A is a 2- to 1-port analog switch. Its wide bandwidth and low bit-to-bit skew allow it to pass high-speed differential signals with good signal integrity. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. Industry-leading advantages include a propagation delay of less than 250 ps, resulting from its low channel resistance and low I/O capacitance. Its high channel-to-channel crosstalk rejection results in minimal noise interference. Its bandwidth is wide enough to pass High-Speed USB 2.0 differential signals (480 Mb/s).

Results for the USB 2.0 signal quality tests will be shown in this section, along with a description of the evaluation test board. The data for the eye diagram signal quality and jitter tests verifies that the NLAS7222A can be used as a data switch in low, full and high speed USB 2.0 systems. Figures 7, 8 and 9 provide a description of the test evaluation board. The USB tests were conducted per the procedures provided by the USB Implementers Forum (www.usb.org), the industry group responsible for defining the USB certification requirements. The test patterns were generated by a PC and MATLAB software, and were inputted to the analog switch through USB connectors J1 (HSD1) or J2 (HSD2). A USB certified device was plugged into connector J4 to function as a data transceiver. The high speed and full speed tests used a flash memory device, while the low speed tests used a mouse. Test connectors J3 and J5 provide a direct connection of the USB device and were used to verify that the analog switch does not distort the data signals. Figure 7.
