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.
http://onsemi.com
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).

APPLICATIONS INFORMATION
The low on resistance and capacitance of the NLAS7222B
(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.
provides for a high bandwidth analog switch suitable for
applications such as USB data switching. 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
