The industry’s first four-channel analog-to-digital converter (ADC) qualified for space applications has been confirmed byTeledyne e2v. The company’s model EV12AQ600 ADC is a radiation-hardened device that can withstand a total ionizing dose (TID) of 150 kRad and provides the exceptional reliability needed to survive long-term missions in satellites and other space vehicles. It meets NASA and ESA requirements according to MIL-PRF-38535 (ML-Y) and ESCC 9000 standards.

The model EV12AQ600 ADC(see image above)features 12-bit resolution and 1.6 GS/s maximum sampling rate across each channel or a maximum rate of 6.4 GS/s for one channel when the four channels are interleaved. The space-qualified ADC can be programmed remotely, such as when the device is in orbit, thanks to a cross-point switch following the input ports and an accompanyingXilinxmodel XQRKU060 field-programmable gate array (FPGA). Programming of such parameters as the number of channels, the bit rate, and the dynamic range can be changed while the FPGA is in space. In addition, a collection of FPGA libraries is available to support different applications using the FPGA ecosystem.

Teledyne E2V的市场总监Nicolas Chantier解释说：“通过我们的空间合格的EV12AQ600设备，我们能够为客户提供可直接集成到其系统的高性能数据转换器解决方案。”“这意味着他们可以从经过飞行的TRL9技术中受益，而无需任何进一步的资格努力。此外，现在库存可用，与这些ADC相关的交货时间比目前在市场上的竞争解决方案要短得多。因此，客户可以立即访问样品。”
