User's Guide SLOU317B – August 2011 – Revised December 2011 TX517 Dual Channel, 17-Level With RTZ, Integrated Ultrasound Transmitter TX517 is a fully integrated, dual channel, high voltage Transmitter designed by Texas Instruments Incorporated. This EVM provides a means to evaluate the functionality of the device. The EVM includes a FPGA to provide an embedded pattern generator and digital control of the device. The output pattern and configuration settings are controlled by 8 push buttons on the EVM.
Buttons 2 www.ti.com Buttons There are eight buttons for controlling the output waveform settings. They are listed in Table 1. Table 1. Buttons Button Functionality PHASE_BUTTON Each time the button is pressed, the current INPx pattern becomes the pattern for INNx, the current INNx pattern becomes the pattern for INPx. PRF_BUTTON Changes the Pulse Repetition Frequency of the output waveform as given in Table 2 Each press increases the PRF and then cycles back to 0.
SYNC Trigger www.ti.com There are 7 patterns: 17-, 5-, 3-, 32-, 4- and 2-level. The patterns are given in Table 6. Table 5. Pattern Depth Index Pattern Depth 0 17 1 5 2 3 3 32 4 4 5 2 6 CW Comments Table 6.
