Product Brief AS3977 PRELIMINARY INFORMATION: SUBJECT TO CHANGE WITHOUT ANY NOTICE www.DataSheet4U.com Multi-Channel Narrowband FSK Transmitter AS3977 1. General Description The AS3977 is a low-power fully integrated ETSI, FCC and ARIB compliant FSK transmitter capable of operating at any ISM frequency in the range of 300 to 928 MHz. It is based on a sigma-delta controlled fractional-N synthesiser phase locked loop with fully integrated voltage controlled oscillator. The power amplifier output is programmable and can deliver output power ranging from –20dBm up to +10dBm. An on-chip low drop-out regulator is available in case an accurate output power independent of voltage supply variation is required.
