AMI Semiconductor's AMIS-53050 wireless transceiver

AMI Semiconductor has developed two single-chip wireless transceivers, the AMIS-52150 and AMIS-53050, which are optimized for sub-GHz, low-to-moderate data rate wireless communications in industrial applications.

The transceivers offer a wide operating frequency range and help reduce the BOM. The operating frequency of the AMIS-53050 can be programmed from 300MHz to 960MHz, while enabling data rates up to 128Kbps. The AMIS-52150 in turn operates from 300MHz to 768MHz, at data rates up to 16Kbps.

The AMIS-52150 and AMIS-53050 incorporate proprietary features designed to reduce power consumption and extend the useful operating life of battery-powered products. The key features include AMI Semiconductor's patented Quick Start oscillator with fast turn-on time of 50?s, as well as integrated circuitry providing for Sniff Mode operation. Such features enable the integrated receiver to quickly respond and poll for the presence of RF signals.

The AMIS-53050 provides multichannel, Frequency Shift Key (FSK) and On/Off Key (OOK) modulation, while the AMIS-52150 allows for OOK modulation. Both devices can be interfaced to a baseband processor via integrated I?C or SPI bus interfaces on the AMIS-53050, and an I?C interface on the AMIS-52150.

In 10,000-piece quantities, the AMIS-53050 and AMIS-52150 are priced at $2.98 and $2.45 each, respectively. For additional information on the AMIS-52150 and the AMIS-53050, visit AMI Semiconductor.
