The Si4720/21 is the first single chip FM radio transceiver. The proven and patented digital architecture of the Si4720/ 21 combines the functionality of the Si470x FM radio receiver with the Si471x FM transmitter, offering full FM receive and transmit capabilities in a single, ultra-small 3x3x0.55 mm QFN package. The device leverages Silicon Lab's highly su.
Integrated FM antenna support Excellent real-world performance Only two external components required Worldwide FM band support (76 to 108 MHz) RDS/RBDS processor (Si4721) Frequency synthesizer with integrated VCO Adjustable seek parameters Adjustable mono/stereo blend Adjustable soft mute Programmable transmit output voltage control Audio dynamic range control Advanced modulation control Analog/digital audio interface Programmable reference clock input Programmable pre/de-emphasis (50/75 µs) 2-wire and 3-wire control interface Integrated LDO regulator 2.7 to 5.5 V supply voltage 3x3x0.55 mm 20.
The Si4720CY is two level-shifted P-Channel MOSFETs. Operating together, these MOSFETs can be used as a reverse blocking.
