The MD1823 features a clock input pin to help realign the input control pins to a master clock signal. This will help minimize delay time errors and clock jitter. A logic input pin, BPS, can be tied high for users not wanting to use the clock realignment feature (if BPS = 1, the clock and registers are ignored). Additionally, MD1823 only uses two input pins for the three level RTZ ultrasound pulser MOSFET gate driver. This feature reduces the FPGA I/O requirement, which simplifies the PCB layout.
"The MD1823 MOSFET driver allows for a much improved discrete ultrasound pulser design," states Jimes Lei, Director of Applications Engineer for Supertex. "The added clock input will minimize time delay errors and jitter to achieve a sharper image."
The MD1823 is available in a lead(Pb)-free/RoHS compliant 16-lead 3x3 QFN package (MD1823K6-G). Samples are available from stock. Lead-time for production quantities is 4-6 weeks, ARO. Pricing is US$1.17 each in 1K quantities.
