1. An optoelectronic device, comprising:
- a receiver configured to receive an optical data stream and to convert the received optical data stream into an electrical input data stream; and
an integrated circuit comprising a clock and data recover integrated circuit, a multiplexer/demultimplexer integrated circuit, or a serializer/deserializer integrated circuit, the integrated circuit configured to generate a loss of lock signal when the input data stream has a data rate out of range of an operational data rate at which the optoelectronic device is set, the integrated circuit further comprising;
a data stream input for receiving the input data stream; and
a data rate select input configured to enable selection and setting of the operational data rate, selected from a plurality of predetermined data rates, of the integrated circuit; and
a controller coupled to the data rate select input and configured to enable automatic adjustment of the operational data rate to one of the predetermined data rates of the integrated circuit in response to receipt of the loss of lock signal.

Abstract
Automatic selection and setting an operational data rate of an optoelectronic device. In particular, an integrated circuit includes a data rate select input for the selection and setting of the operational data rate. The integrated circuit internally generates a loss of lock signal if an input data rate does not match the operational data rate. The integrated circuit then automatically sets and selects operational data rates within a predetermined range of operational data rates until the loss of lock signal is deasserted or until all of the rates within the predetermined range of operational data rates have been attempted.
