Quad Channel Cross-Point Analog Transmit/Receive Switch From Supertex Offers 
Design Flexibility for Medical Ultrasound Systems 
MD0201 Features 4x4 Cross Point Switching Topology Offering Lower
Noise Routing to Multiple Receivers 
SUNNYVALE, CA -- (Marketwired) -- 11/26/13 --  Supertex (NASDAQ:
SUPX), a recognized leader in high voltage analog and mixed signal
integrated circuits (ICs), today introduced the MD0201, a low voltage
four-channel T/R analog cross point switch designed for medical
ultrasound imaging applications.  
The MD0201 includes low voltage CMOS analog switches and digital
control logic for serial interface control circuits, as well as
provision of voltage limiting diodes and output shunt switches. The
analog switches have low insertion loss, low noise, wide frequency
response, high off-isolation and low channel-to-channel crosstalk.
The output shunt switches prevent overloading the low noise
amplifier. Inputs are connected to the output of the two terminal
type ultrasound T/R switches, with the two back-to-back diodes
providing voltage limiting. The buffered serial interface data
registers allows maximum design flexibility to connect multiple
channels for better signal routing. 
"As medical diagnostic ultrasound systems increase in both
portability and channel density, Supertex remains committed to
providing innovative products to ultrasound equipment manufacturers
with the highest performing ICs on the market," states Jimes Lei,
Director of Application Engineering of Supertex. "The MD0201 topology
provides more system design flexibility for image quality
enhancement."  
The MD0201 is available in a lead(Pb)-free/RoHS compliant 48-lead 7x7
QFN package (MD0201K6-G). Samples are available from stock. Lead-time
for production quantities is 4-6 weeks, ARO. Pricing is US$10.38 each
in 1K quantities.
