20150280950 | Signal Processing - Described herein is a multi-level to binary converter in which a cascade of differential limiting amplifiers are utilised for each signal path to provide both increased gain and increased bandwidth without having to trade one off against the other. Where the multi-level data is duobinary, cascaded amplifiers are coupled to a XOR logic gate. In each path, a copy of the duobinary signal is level shifted using an adjustable threshold before amplification in an amplifier. The shifted and amplified signal is then fed to another amplifier where it undergoes the same steps. The outputs from each path are fed to the XOR logic gate to generate the desired binary signal, corresponding to a decoded synchronized NRZ data stream. Such a multi-level to binary converter is capable of performing at data rates of 50 to 80 Gb/s and above, and can easily be integrated within a chip for high-speed electrical backplane communication, optical backplanes or optical fibre links. | 10-01-2015 |
