Abstract:
1. A signal modification integrated circuit suitable for use in connection with an optoelectronic device, the signal modification integrated circuit comprising: a receive circuit configured to operate at any one of a plurality of automatically selectable data rates and further configured to generate a loss of lock signal when a data stream associated with the receive circuit has a data rate out of range of an operational data rate at which the optoelectronic device is set, and the receive circuit being configured to set the operational data rate of the optoelectronic device to successive data rates included in the plurality of automatically selectable data rates, wherein when each data rate in the plurality of automatically selectable data rates have been set but the loss of lock signal remains asserted the receive circuit is configured to cause the data stream to be passed through the signal modification integrated circuit without modification; and a transmit circuit configured to operate at any one of a plurality of automatically selectable data rates and further configured to generate a loss of lock signal when a data stream associated with the transmit circuit has a data rate out of range of an operational data rate at which the optoelectronic device is set, and the transmit circuit being configured to set the operational data rate of the optoelectronic device to successive data rates included in the plurality of automatically selectable data rates.
