SX061
1 Mbit/s DQPSK/DBPSK
General Description
The SX061 is a digital demodulator, specially developed to work together with the AMI SX043 Spread Spectrum
baseband processor. This 24 pin integrated circuit replaces many analogue components needed to work with the
SX043 or SX042. This chip is only needed on the receiving radio unit (FIGURE 1). The transmitting radio unit needs
no special requirements to generate the DQPSK or DBPSK signal other than the output of an SX041 or an SX043.
