Overview
The SN65HVD64RGTR is an integrated AISG (Antenna Interface Standards Group) transceiver designed and manufactured by Texas Instruments. This device is specifically engineered to meet the requirements of the AISG v2.0 and v3.0 specifications. It facilitates wired data transfer among radio equipment by modulating and demodulating signals between a logic (baseband) interface and a frequency suitable for long coaxial media.
The SN65HVD64RGTR integrates an active bandpass filter with a 2.176-MHz center frequency, enabling the demodulation of signals even in the presence of spurious frequency components. The transmitter supports adjustable output power levels from 0 dBm to 6 dBm, ensuring compliance with the spectrum emission requirements of the AISG standard.
