Description

The RX3141 is a low power IF receiver IC which is fully compatible with the Toshiba TA31145 IC and is suitable for use as the second IF downconverter in double-conversion paging systems. The RX3141 is well-suited for POCSAG paging applications and incorporates a 2-level FSK demodulator consisting of a quadrature FM demodulator, on-chip bit-rate filter, and 1-bit comparator. An on-chip 1 V regulator of the RX3141 is provided for convenient biasing of off-chip circuitry. In addition, an RSSI voltage output is included as a measure of the received signal strength.
