• LTC2157-14 conversion errors at 250MHz sampling rate

    I am using LTC2157-14 in a design.

    In the last production run (10 units) i get conversion errors on all boards when sampling at 250MHz.

    What i call a conversion error is a single sample with very high amplitude when measuring noise (shorted input), typically…

  • LTC2157 2-Tone IM3 at 140MHz?

    What is LTC2157 Two-Tone Input IM3 at 140MHz? 

    I don't see any IM3 info in the datasheet, and I only see one spectral plot with a 2-tone input around 70MHz.

    Are there more 2 tone plots or IM3 versus input frequency data available anywhere?

    I connected an FPGA to the Blackfin address/data bus for accelerating arithmetic computations.

    Is there a way to unprotect certain addresses in user space so that…
