10-Bit Broadband Data Converter Operates Beyond 35 GHz
This video is part of our electronica 2022 coverage.
Teledyne e2v showcased its EV10AS940, the company's latest advanced 10-bit broadband data converter—a part of its push into software-defined microwave technologies. Conventional radios still use heterodyning to mix two signal frequencies in a nonlinear mixer. Moving to high-bandwidth direct-conversion devices enables significantly simplified, software-defined receivers with frequency agility. In a major front-end architectural change, the solution employs single-ended design rules for the clock and signal lines; thus, frequency-dependent baluns can be eliminated.
Frequency planning, signal demodulation, filtering, and front-end design all benefit, and integrated digital-assist features enhance receiver operation. Four independent numerical controlled oscillators enable agile frequency hopping, and a programmable digital downconverter provides a variety of decimation intervals from 1 to 1,024. The device connects via license-free ESIstream serial links to FPGA-based signal processing, with a multichannel synchronization facility for synchronous sampling across a plurality of devices.
