Low-Pass Filter
PSPL5935 Datasheet
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-Thomso n fil ter . Tradi tional Bess el-Thomson
designs filter by reflecting stop-ba nd fr eq uency signal s and thus can caus e
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-directi on al , so either port may be used as the input.
