Description
Silicon Labs’ Si4020 is a single chip, low power, multi-channel FSK transmitter designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 315, 433, 868, and 915 MHz bands.
Features
- a completely integrated PLL for easy RF design, and its rapid settling time allows for fast frequency hopping, bypassing multipath fading and interference to achieve robust wireless links. In addition, highly stable and accurate FSK modulation is accomplished by direct closed-loop modulation with bit rates up to 256 kbps. The PLL’s high resolution allows the use of multiple channels in any of the bands. The integrated power amplifier of the transmitter has an open-collector differential output t.
