ABSTRACT:
A method, in a host adapter circuit configured for coupling a host electronic device with one of a fiber channel loop and a point-to-point communication channel, for receiving data at the host adapter circuit from one of the fiber channel loop and the point-to-point communication channel. The method includes providing a selectable control signal configured for indicating whether the host adapter circuit is coupled to the fiber channel loop or the point-to-point communication channel. The method further includes providing a front-end receive circuit. The front-end receive circuit is configured for coupling with an input data port. The input data port represents one of the fiber channel loop and the point-to-point communication channel. The method also includes coupling the front-end receive circuit with the selectable control signal. Additionally, the method includes coupling an output of the front-end receive circuit with a decoder of the host adapter circuit, wherein the front-end receive circuit is configured to process, responsive to the selectable control signal, either fiber channel loop data from the fiber channel loop or point-to-point data from the point-to-point communication channel from the input data port to provide parallel data having a predefined size to the decoder circuit.
