            I read in the DRS datasheet that the input bandwidth if 950MHz. However, it also says the output bandwidth

            in the datasheet it says at 6GSPS the typical loop filter parameters are 220Ω, 2.2nF and 27nF.

Hi, Stefan,

I found that my collaborator bought 2 older version of evaluation board before.

Entry  Tue May 18 09:24:02 2010, Stefan Ritt, Reference design for DRS4 active input buffer ac.pngac_bw.pngdc.pngdc_bw.pngDRS4_ft_V3.jpg
The design of high frequency differential input stages with the DRS4 is a challenge, since the chip draws quite some current at the input (up to 1 mA
at 5 GSPS), which must be sourced by the input buffer. A simple transformer as used in the DRS4 Evaluation Board 2.0 limits the bandwidth to 220 MHz. In
meantime two active input stages have been worked out and successfully been tested, both utilizing the THS4508 differential amplifier. The first design
