SUNNYVALE, CA -- (Marketwire) -- 03/27/13 --  Supertex (NASDAQ:
SUPX), a recognized leader in high voltage analog and mixed signal
integrated circuits (ICs), today introduced the HV7351, an eight
channel, programmable high voltage ultrasound transmit beamformer
specially designed for medical diagnostic ultrasound applications.  
Each channel of the HV7351 is capable of swinging up to +/-70V with
an active discharge back to 0V. The outputs can source and sink more
than 3.0A to achieve fast output rise and fall times. The active
discharge is also capable of sourcing and sinking 3.0A for a fast
return to ground. Each output is controlled by a 32-bit serial shift
register. An arbitrary pattern can be generated depending on what is
loaded into the shift registers. Up to four independent patterns can
be loaded. This allows users to quickly change mode, for example,
B-mode to PW-mode quickly without having to clock in new data. A
programmable 200MHz 10-bit delay counter is provided for each output
allowing the users to program different delay times for each channel
for beamforming. Once the patterns and delay times are loaded, a
single logic trigger command can fire all eight channels with the
selected pattern and associated delay times. 
The Supertex HV7351 topology will significantly reduce the number of
I/O logic control lines needed for the transmitter, which have been a
major concern in complexity and board space layout. "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. "This versatile, high voltage,
high density, programmable transmit beamformer IC will reduce the
number of I/O connections, simplify PC board layout, and minimizes
delay time errors." 
The HV7351 is available in a lead(Pb)-free/RoHS compliant 80-lead
(11x11) QFN package (HV7351K6-G). Samples are available from stock.
Lead-time for 
production quantities is 4-6 weeks. Pricing is US$28.78
each for the HV7351K6-G in 1K quantities.
