Pure differential signal based MIPI DSI/CSI-2 receiver systems

摘要

A circuit may include a splitter, a controller, and a termination. The splitter may generate, based upon input signals, a plurality of output signals, wherein at least one of the input signals is in more than one different modes at different times and the output signals comprise a first set of the output signals generated based upon comparison of pairs of signals of the first set against each other and a second set of the output signals generated based upon comparison of each signal of the second set to a predetermined threshold voltage. The controller may determine, based upon the second set of the output signals, whether the input signals are in the one of the more than one different modes to generate one or more control signals. The termination may connect loads to each of the input lines, based upon the one or more control signals.

1. A circuit, comprising:
a splitter generating, based upon a plurality of input signals received on a plurality of input lines, a plurality of output signals, wherein at least one of the input signals is in more than one different modes at different times and the output signals comprise a first set of the output signals generated based upon comparison of pairs of signals of the input signals against each other and a second set of the output signals generated based upon comparison of each signal of the input signals to a predetermined threshold voltage; a controller determining, based upon the second set of the output signals, whether the input signals are in the one of the more than one different modes to generate one or more control signals; and a termination connecting loads to each of the input lines, based upon the one or more control signals.
