NLAS7222B, NLAS7222C High-Speed USB 2.0 (480 Mbps) DPDT Switches ON Semiconductor's NLAS7222B and NLAS7222C are part of a series of analog switch circuits that are produced using the company's advanced sub-micron CMOS technology, achieving industry-leading performance. Both the NLAS7222B and NLAS7222C are 2- to 1-port analog switches. Their wide bandwidth and low bit-to-bit skew allow them to pass high-speed differential signals with good signal integrity. Each 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. Their high channel-to-channel crosstalk rejection results in minimal noise interference. Their bandwidth is wide enough to pass High-Speed USB 2.0 differential signals (480 Mb/s). http://onsemi.com MARKING DIAGRAM UQFN-10 CASE 488AT 1 XX XX MG G Device Code xx = 2A or Y M = Date Code G = Pb-Free Device (Note: Microdot may be in either location) Features •RON is Typically 8.0 at VCC = 3.3 V •Low Bit-to-Bit Skew: Typically 50 ps •Low Crosstalk: -30 dB @ 250 MHz •Low Current Consumption: 1.0 A •Near-Zero Propagation Delay: 250 ps •Channel On-Capacitance: 8.0 pF (Typical) •VCC Operating Range: 1.65 V to 4.5 V •> 700 MHz Bandwidth (or Data Frequency) •These are Pb-Free Devices = ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 8 of this data sheet.

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 NLAS7222B can be used as a data switch in low, full and high speed USB 2.0 systems. Figures 8, 9 and 10 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 8.
