The TMS3705CDRQ1 from Texas Instruments is a specialized Transponder Base Station IC engineered for TI-RFid™ RF Identification Systems. This component is crucial for driving the antenna in a transponder system, enabling the transmission of modulated data, and effectively detecting and demodulating the transponder's response, which is communicated via a frequency shift keyed (FSK) signal.
The IC supports distinct high-frequency signals for coding low bits (134.2 kHz nominal) and high bits (123 kHz nominal). It features essential protective functions such as short-circuit protection and diagnosis capabilities. Designed with automotive requirements in mind, the TMS3705CDRQ1 operates with a low sleep-mode supply current of 0.2 mA. It interfaces with external microcontrollers and is housed in a 16-pin SOIC package.
Applications for this IC include car access, immobilization systems, building access control, and livestock readers. The device includes an on-chip PLL that generates a 16 MHz clock frequency for internal use. The datasheet indicates specific configurations for clock supply to both the microcontroller and the base station IC, either sharing a single resonator or utilizing separate resonators.
