APPLICATIONS INFORMATION
The low on resistance and capacitance of the
NLAS7222A 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 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.
