General Description

The MD1213DB1 can drive a transducer as a single chan-

nel transmitter for ultrasound and other applications. The

demoboard consists of one MD1213 in a 12-Lead 4x4x0.9mm

QFN (K6) package, combined with Supertex’s TC6320, an

IC containing high voltage P- and N- channel FETs in a 8-

Lead SOIC package.

Logic control inputs INA, INB and OE of the MD1213 are

controlled via the six-pin head connector on the board. Due

to the fast signal rise and fall time requirement, every ground

wire of the ribbon cable must be used to connect from the

logic signal source. When OE is enabled, it should recieve

the same voltage as the logic source circuit’s power supply.

The MD1213DB1 output waveforms can be displayed direct-

ly using an oscilloscope by connecting the scope probe to

the test point TP10-1 and TP10-2 (GND). The J5 jumper can

select whether or not to connect the on-board equivalent-

load, a 220pF 200V capacitor paralleled with a 1.0kΩ, 1W

resistor. Also, a coaxial cable can be used to easily connect

to the user’s transducer.

Demoboard Features

Designing a Pulser with the MD1213

Low input capacitance and fast switching speed are the im-

portant features of the MD1213’s input stage. Its logic inputs

have an input impedance of about 20kΩ in parallel with 5pF,

and an internal speed of around 100MHz. The output enable

pin, OE, determines the threshold voltage for the input-chan-

nel level translators. The MD1213’s input stage logic is fully

compatible with 1.8V, 2.0V, 2.5V, 3.3V, or 5.0V CMOS logic.

The level translators are also compatible with these logic

voltage levels right up to the MOSFET’s gate-driver voltage

level, which is typically 5.0V to 12V. When OE is low, the

chip disables its’ outputs, setting OUTA high and OUTB low.

This condition helps to properly pre-charge the AC coupling

capacitors that the user can optionally add in series with the

gate-driver circuit of the external P/N-channel FET pair.
