Low-Pass Risetime Filter

The PSPL5915 Low-Pass Rise time Filter is designed for use in high-speed digital networks and telecom systems. The -3 dB bandwidth of the standard filters is 0.75 * Bit Rate. These filters are a proprietary, absorption filter design that has attenuation and group delay responses similar to those of the Bessel-Thomson filter. Bessel-Thomson filters filter by reflection and thus can cause increased bit error rates and eye diagram closure due to multiple reflections. By contrast, the PSPL5915 filters by absorption. It has excellent impedance matches and very good return losses, both within and above the filter pass band.
