RTC6715 Datasheet – CMOS 5.8GHz Band FM Receiver
RTC6715 overview
The RTC6715 is a CMOS 5.8GHz Band FM Receiver, supplied in a 48-pin Leadless QFN package. The absolute maximum ratings table on this page lists the 5 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the RTC6715 pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The RTC6715 is a highly integrated FM receiver intended for application on 5.8GHz band FM demodulation. This chip includes a low noise amplifier, mixer, IF amplifier, FM demodulator, AGC, audio demodulators, audio Amps and noise squelch. With RSSI voltage output, the instantaneous radio signal strength can be monitoring. RTC6715 is able to demodulate the FM modulated video and Stereo audio signals sourced from RTC6705 and separate the desired signal at the dedicated output pins. Both Stereo and Mono application are available on the chip.
RTC6715’s operation frequency can be set by SPI programming, or by selecting six dedicated pins. Both CE and FCC regulations are easy to pass by using RTC6715 with application circuit and single room shielding case.
