The PSPL5935 Low-Pass Filters are designed for OEM use in high speed digital networks and telecom systems. The devices use a proprietary, absorptive filter design that has attenuation and group delay frequency responses similar to those of the 4th order Bessel-Thomson filter. Traditional Bessel-Thomson designs filter by reflecting stop-band frequency signals and thus can cause increased bit error rates and eye diagram closure due to multiple reflections. By contrast, the PSPL5935 filters by absorption. They have excellent impedance matches and very good return losses, both within and above the filter pass band. This filter is bi-directional, so either port may be used as the input.
