TRF7900PWR [Texas Instruments]

The TRF7900 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. It features high data throughput rate, 23 discrete components integrated into one chip, 5-kHz square wave simultaneously per channel, 10 kbps Miller encoded data, I2C control interface, received signal strength indicator, 5-V supply, available in 28-pin TSSOP package, integrated phase locked loop, 8 user-selectable frequencies, and internally generated 6-MHz clock to drive USB microcontroller.
