    Hello, 

    I am trading several components that do not have process or reliability data on the wafer fab page. I was wondering if I could have the process used to manufactuer the LT3045, LTC6957 and HMC1034. 

    Thank you

    The HMC987 1K pull-down is necessary on SDO to fix an error in the output driver.  This output is actually an open drain pull-up to 300 ohm instead of standard CMOS drive.  Without the resistor the output cannot drive low.  No clocks are required to access…
