Overview

AS3901 ISM 433/315 MHz FSK/ASK Transmitter Data Sheet Rev.
06, August 2000 ISM 433/315 MHz FSK/ASK Transmitter – Data Sheet AS3901 Key Features • • • • • • • • • • • Supports the European 433 MHz ISM band.
No frequency pulling by (antenna) load variation due to PLL synthesizer.
Designed to be conform to EN 300 220-1 requirements.
Supports FSK (data rates 0… 32 kb/s) or ASK modulation (data rates 0… 20kb/s) No data synchronization for FSK or ASK needed.
Supports clock and reset signals for the external µC.
Supports different power down modes, one without any running XTAL oscillator.
Wide supply range between 2.
7 V to 5 V.
Only one XTAL and very few external elements required.
Wide operating temperature range from –40 C to +85 C.
Low TX current, typical 7 mA.
General Description The AS3901 is a low power FSK/ (ASK) transmitter intended for the European 433 MHz and the US 315 MHz ISM band application.
It uses a PLL stabilized oscillator which avoids frequency pulling by approaching the...
