Page 9: Introduction
Chapter 1 Introduction The TRF3750 EVM provides a platform for evaluating the TRF3750 integer-N PLL frequency synthesizer under various signals, reference, and supply conditions. This document should be used in combination with the EVM schematic diagram supplied. Using the TRF3750 EVM, you can rapidly evaluate the TRF3750 PLL with a minimum of manual setup. -

EVM Configuration 3.1 EVM Configuration The TRF3750 EVM can be set up in a variety of configurations to accommodate a specific mode of operation. Before starting evaluation, the user should decide on the configuration and make the appropriate connections or changes. The basic synthesizer circuit is shown in the schematic (Chapter 5). - Page 25 EVM Configuration access to the MUXOUT pin. An LED is also connected for visual identification. Note that R13 and R14 are removed. R12 limits the current going into the LED. To connect the MUXOUT output to the parallel port connector J5, install R2 (0 Ω). W1—This jumper controls the chip enable.
