X-Digital Systems will use Analog Devices’ Blackfin processor in its new XDS-PRO4 low-cost satellite receiver that allows satellite operators to distribute broadcast grade audio content to US radio stations.
Analog Devices’ Blackfin 16/32-bit embedded processor is designed for applications where a convergence of capabilities, such as multi-format audio, video, voice and image processing, multi-mode baseband and packet processing, and real-time security and control processing, are critical.
X-Digital’s XDS-PRO4 satellite receiver converts streaming digital audio to analog baseband audio using the ADSP-BF537 Blackfin processor as a high-density MPEG 1 Layer 2 Audio decoder. The Blackfin processor handles eight MPEG 1 Layer 2 Audio streams.
The XDS-PRO4 satellite receiver also uses Analog Devices’ analog technology. ADI’s ADAU1328 is an octal 24-bit, 192KSPS audio digital-to-analog converter (DAC) that enables the transmission of audio channels to the stations broadcast operations systems. Also designed into the XDS-PRO4 are ADI’s ADT7476A for system monitoring and fan control, the ADT75A digital temperature sensor for thermal monitoring, the SSM2142 for balanced line driving, the AD5601 nanoDAC digital-to-analog converter for gain control and the OP275 Audio Operational Amplifier to maintain accuracy and reduce noise throughout the signal chain.
“With the XDS-PRO4 satellite receiver, X-Digital is taking aim at the low-cost professional audio market. Such a high-performance application requires flexible yet cost effective DSP functionality,” said Laurence Fish, CTO, X-Digital Systems. “Analog Devices’ Blackfin has helped us bring to market a satellite receiver that makes it possible to deliver professional-grade features at a price typically seen on consumer products.”
