Abstract
A floating clock data recovery circuit may be positioned anywhere in a chain of nodes. An N+1 length series of port bypass circuits are connected such that the output port of one is connected to the input of the next port bypass circuit. N is the number of desired nodes. One of the series of port bypass circuits will be used to 'control' the positioning of the signal conditioning circuitry. When the control PBC is in operation, the loop is 'broken' at that node. As a result, the signal conditioning circuitry may be placed anywhere in the chain of nodes.
