K&L's line of Transmission Time Converters, TTC's, are lowpass filters designed specifically for use in high speed data rate transmission systems. Intersymbol Interference (ISI), which appears as noise, can degrade system performance. These lowpass filter designs are specifically configured to minimize the ISI by controlling the rise time of the time domain response. This is achieved by presenting flat group delay and impedance matching up to 3 times the 3 dB cutoff frequency. The filters are available in a variety of transition times in order to accommodate systems with virtually any bit-rate. While standard models are available covering transition times of 35 pico-seconds to 9 nano-seconds, customized transition times are available as well.
