Hi Team,
This is Rohit Gupta from Applied Electro Magnetics Pvt. Ltd. We are currently working on a project that requires susceptibility compliance in accordance with MIL-STD CS117. The project involves both single-ended and differential data lines.
Could you please suggest suitable protection methods for these data lines to ensure compliance with the CS117 standard?
Thanks

Hi Gupta,
Could you please suggest suitable protection methods for these data lines to ensure compliance with the CS117 standard?
Here is a typical input surge current protection for PGA2505.
For CS117 compliance, you may need incorporate additional common mode chokes, TVS diodes, ferrite beads, shielded cable and filtering and proper EMI coupling and grounding to meet the compliance requirements.
In many ways, the CS117 is system level compliance test, and above mentioned protection techniques are addressed and applicable to the system level in CS protection. PGA2500 is sitting on at a component level, unless the amplifier has to interface directly to an outside world, then the above mentioned protections will be required.
In addition, the CS117 has many compliance waveforms (based on DO-160 CS test requirements), some waveforms are voltage based; some are current waveforms based; and you have to design the system (DUT) and comply with the CS117 tested waveform requirements.
if you have additional questions, please let me know.
Best,
Raymond
