  • Page 2 • Programming cable Software Setup The LabVIEW™ software provided by Texas Instruments on the accompanying CD is the software that configures the TRF3762. It is used to set the registers inside the device for normal operation. The LabVIEW software interfaces to the EVM via a DB25 connector. The chip uses a SPI interface protocol with data formatted as little endian, which means the LSB is clocked in first.

  • Page 10 Appendix A www.ti.com Appendix A Synthesizing Desired Frequencies Prescalar Div is a multiselection dual modulus to limit the frequency of the Prescalar to below 250 MHz. The setting are 8/9, 6/17, 32/33, and 64/65. The TRF3762 has an integer-N PLL synthesizer, and because of its flexibility (14-bit R, 6-bit A, 13-bit B counter, and dual modulus prescalar), is ideal for synthesizing virtually any desired frequency.
