MD1730 8-Channel Ultra-Low Phase Noise Continuous Waveform Transmitter with Beamformer • 8-Channel Ultrasound Continuous Waveform CW Transmitter with Integrated Beamformer • CW Output ±1V to ±6Vp-p with Low RON • -160 dbc/Hz Ultra-Low Phase Noise at 1 kHz Offset and 5 MHz • 8-Bit Programmable Per-Channel Beamforming Phase Delay • 8-Bit Programmable Dividers for CW Frequency with Input Clock Frequency up to 250 Mhz • Input Clock Compatible with LVDS/SSTL or Single-Ended LVCMOS • LVCMOS 2.5V Logic for the Control I/O pins • Fast SPI Interface Supports up to 200 MHz • SPI Interface Supports Daisy Chaining and Broadcasting Mode • Medical Ultrasound Imaging System for Cardiovascular Application • Ultrasound Fetal Heart Monitoring Device • Ultrasound Flow Meter • Programmable Array Pattern Generator The MD1730 is an 8-channel ultra-low phase noise CW transmitter with integrated beamformer. It is designed for medical ultrasound imaging systems requiring high-performance CW Doppler mode. The MD1730 has a dedicated signal path designed to minimize phase noise to the output. In addition, it has a high-speed SPI interface that enables CW beamforming features. The outputs of the MD1730 can swing up to ±6V and each output has a separate programmable phase delay. Additionally, by programming the internal frequency divider register, the MD1730 can output different CW frequencies from a single clock source. For instance, when the input clock frequency is 160 MHz and the frequency divider is set to 16, an output CW frequency of 5 MHz can be obtained with a phase delay step size of ns, which translates to an angular resolution of degrees.

Note the following details of the code protection feature on Microchip devices • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.
