M21324

3G/HD/SDI-SDI Cable Equalizer

The M21324 is a high-speed, low power, adaptive co-axial cable equalizer designed to increase the maximum low jitter transmission distance of serial digital interface (SDI) video signals and DVB-ASI across commonly used bandwidth-limiting 75O coaxial cable. This device automatically optimizes the transfer function based on the bit rate and cable length to minimize the inter-symbol interference (ISI) jitter caused by the cable and to remove the DC offset components introduced with the pathological test pattern and AC coupling in systems. The M21324 is designed to support SD, HD, and 3G data rates from 143 Mbps to 2970 Mbps. The low noise, high gain equalizer allows for low jitter 3G transmissions up to 100m (Belden 1694A) and HD transmissions up to a length of 200m (Belden 1694A) and 120m (Belden 8281). For SD data rates, cable lengths up to 400m (Belden 1694A) and 300m (Belden 8281) are supported.
