Abstract
Apparatus and methods are provide for a multichannel clock and data recovery (CDR) device that shares information between channels. In an example, a multiple channel communication circuit can include a plurality of clock and data recovery (CDR) circuits, each CDR circuit of the plurality of CDR circuits associated with a channel of the multiple channel communication circuit. In certain examples, each CDR circuit can be configured to detect an incoming stream of data from the channel, to determine a setting of one or more parameters for correctly sampling the data from the incoming stream, and to share an indication of the setting of the one or more parameters to an adjacent CDR circuit of the plurality of CDR circuits.
