1 MD Ultrasound Beamforming Transmitter Demoboard Introduction The MD is a high speed, arbitrary waveform, push-pull source driver. It is designed for medical ultrasound imaging and HIFU beamforming applications. It also can be used in NDT, sonar and other ultrasound phase-array focusing beamforming applications. The integrated circuit (IC) consists of the CMOS digital logic input circuits, an 8-bit current DAC for the waveform amplitude control, and four PWM current sources. These current sources are constructed with the high speed in-phase and quadrature current switch matrix and the built-in sine and cosine angle-to-vector look-up table. The angular resolution of the vector table is 7. degrees per step with a total range of 8 steps. There are four logic input signals to control the inphase and quadrature PWM push-pull current source s output timing frequency cycle in the burst and waveform envelope. MDDB General Description This MDDB datasheet describes how the demoboard is to used to generate the ultrasound transmit beamforming waveform with the Gaussian profile, and the adjustable frequency, amplitude and phase angle. It also provides information about how to design a user application circuit and PCB using the Supertex MD and DN devices. The MDDB circuit uses two depletion-mode MOSFETs in the push-pull mode to drive the center tapped, wide band, ultrasound output transformer. The two depletion-mode MOSFETs are packaged in a single xmm DFN package. The sources of the MOSFETs are directly driven by the MD s two outputs, whose maximum peak sinking current is up to.0a. These current source outputs are controlled by the MD s internal angular vector switch matrix and the in-phase and quadrature PWM input signals. The MD s output stage is designed to drive two depletion mode, high voltage, Supertex DN MOSFETs as a source driver. The MOSFET drains are connected to a center-tapped ultrasound frequency pulse transformer. The secondary winding of the transformer can connect to the ultrasound piezo or capacitive transducer via a cable with a good impendence match. The MD has a high speed serial data interface that quickly updates the data register s per-scan-line for changing the beamforming phase angles and apodization amplitudes. All of the MD s logic control signals are generated by two small CPLD programmable logic circuits clocked by an on-board 0MHz crystal oscillator. The CPLD circuits not only generate accurate timing for the high speed PWM control waveforms, but also the serial data and clock to set and change the waveform amplitude DAC and phase angle data registers. The external clock input can be used if the on-board oscillator is disabled. The external trigger input can be used to synchronize the burst waveforms launch timing. There are five push buttons for enabling and selecting the output wave- Demoboard Block Diagram +.V +.V JTAG +.V +.0V +.0V +.V EXTRG EXCLK OSC 0MHz DIS Wave Freq Ampl Phase A EXTRG CLKIN IO CPLD IA QA IB QB SDI SDO SCK CS LD PHO DAC PWR VLL VDD PA MD RFB PB +70 to 00V V PP DN C7 DN +.0V +.V T :: JUMP k 0pF LOAD XDCX Doc.# DSDB-MDDB A070
2 MDDB form frequency, phase angle and amplitude. Four color LEDs indicate the power, chip enable and wave-form parameter selection states. The MDDB output waveform can be displayed by using an oscilloscope and the high impedance probe at the TP test point. It also can use an SMA to BNC, 0Ω, coaxial cable to directly connect to an oscilloscope, with an attenuation of : if R0 is 00Ω. A cable can also be used to directly drive the user s transducer. Jumper J can be used to select whether or not to connect the on-board equivalent load, which is formed by a 0pF capacitor in parallel with a.0kω resistor. Circuit Design & PCB Layout The thermal pad at the bottom of the MD package must be connected to the VSUB pin on the PCB. The VSUB is connected to the IC s substrate. It is important to make sure that the VSUB is well grounded. A proper supply voltage power-up sequence is needed to test the circuit. To prevent any supply voltage polarity reversing, the circuit also has the protection of Schottky diodes D7, D8 and D9. Due to the high current and high current slew rate nature of this common gate, source driven and push-pull circuit topology, the two cascading N-channel MOSFETs need to have very low lead inductance. The DNDK MOSFET is designed for this application and works seamlessly with the MDK7. In particular, a good PCB layout design needs to shorten the traces between the MDK7 output pins and DNDK source pins. It is also necessary to connect all three pairs of pins between them for the high current carrying capacity. Furthermore, because of the high di/dt in the output current of the MD, it is also necessary to have the Schottky diodes D and D from the driver output pins to the +.0V power supply line as the clamping diodes. Note that the diodes must have enough speed and peak current capability. The RC snubber circuits of R8-C and R-C8 at the output pins can dump the current pulse edge ringing effectively. PCB designers need to pay attention to some of the connecting traces as high voltage and high speed traces. In particular, low capacitance to the ground plane and more trace spacing need to be applied in this situation. High speed PCB trace design practices that are compatible with operating speed of about 00 to 00 MHz are used for the demo board PCB layout. The internal circuitry of the MD can operate at quite a high frequency, with the primary speed limitation being load capacitance. Because of this high speed, and the high transient currents that result when driving even very small inductive loads, ringing and even oscillations are possible. The supply voltage bypass capacitors and the MOSFET gate decoupling capacitors should be as close to the pins as possible. The capacitor s ground pin pads should have low inductance feed-through connections that are connected directly to a solid ground plane. The VDD and VPP supplies can draw fast transient currents of up to.a, so they should be provided with a low impedance bypass capacitor at the chip s pins. A ceramic capacitor of to.0µf may be used. Minimize the trace length to the ground plane, and insert a ferrite bead in the power supply lead to the capacitor to prevent resonance in the power supply lines. For applications that are sensitive to jitter and noise and using multiple MD ICs, insert another ferrite bead between VDD, and decouple each chip supply separately. Pay particular attention to minimizing trace lengths and using sufficient trace width to reduce inductance, not only on the supply pins but also on the CA/B and KA/B compensation pins. Very closely placed surface mount components are highly recommended. Be aware of the parasitic coupling from the high voltage outputs to the input signal terminals of MD. This feedback may cause oscillations or spurious waveform shapes on the edges of signal transitions. Since the input operates with signals down to.v, even small coupling voltages may cause problems. The use of a solid ground plane and good power and signal layout practices will prevent this problem. Also ensure that the circulating ground return current from a capacitive load cannot react with common inductance to create noise voltages in the input logic circuitry. This MDDB beamforming demoboard should be powered up with multiple DC power supplies with current limiting functions. The power supply voltages and current limits used in the testing are listed on page. There are examples of the MDDB demoboard input and output waveform and measurements shown in Figures to 9. Output Transformer Design A center tapped wide band ultrasound transformer is needed for the push pull output circuit. The transformer serves at least three functions: the balanced differential to single end RF output transformer; the isolation barrier to the ultrasound probe; and the impedance matching or low pass net work combined with the cable and transducer element. The MD PWM clock may operate at a 0 to 0MHz frequency range, however the wide band transformer only needs to work in the frequency band of the ultrasound being transmitted. Beside the bandwidth consideration, the transformer also needs enough peak current capacity and RF power coupling efficiency to make sure the ferrite magnetic core will not be saturated, have little leakage inductance and will be a small size.
