PSPL5933 Flat Group Delay Low-Pass Filter Datasheet
The PSPL5933 Flat Group Delay Low-Pass Filter is designed for OEM use in high-speed digital networks and telecom systems. The devices use a proprietary, absorptive filter design that has attenuation and time domain characteristics 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 PSPL5933 filters by absorption. It has excellent impedance matches and very good return losses, both within and above the filter pass band. The Flat Group Delay style filter exhibits quasi-Gaussian insertion loss characteristics, with superior time domain performance.
