DESCRIPTION

The TRF7900A is a dual integrated RF transceiver designed for human-interface devices (HID). Operating at 27

MHz, it integrates multiple components (PLL, RF mixer, simulated SAW filter, tuning circuit, and miscellaneous

passive components) to provide frequency selection from 8 discrete channels. This integration lowers

component, manufacturing and system costs.

The TRF7900A simplifies system design by reducing system component count and manual circuit tuning. By

integrating the PLL, SAW filter, and RF mixer, the TRF7900A eliminates the manual tuning of RLC circuits

required in traditional implementations.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
