AMIS-53050 Frequency Agile Transceiver
Data Sheet
1.0 Overview of the AMIS-53050
The AMIS-53050 is a highly integrated and configurable single-chip wireless transceiver and is based on AMI Semiconductor’s
ASTRIC™ wireless solutions platform. It is ideally suited for multi-channel (sub-1GHz), low to moderate data rate, low power, narrow
band wireless applications in the automotive and industrial markets. The device provides for a number of data modulation schemes,
including frequency shift key (FSK), Gaussian FSK (GFSK) and on/off shift key (OOK) modulation, respectively. The AMIS-53050 can
be easily interfaced to a baseband processor via a serial interface bus.
