An integrated circuit can operate in a first mode as a parallel-to-serial converter, and in a second mode as a serial-to-parallel converter. Some of the components of the integrated circuit are used in both modes. For example, the IC has a single parallel interface, which is used as a parallel input in the first mode, and as a parallel output in the second mode. Further, the IC includes a single phase-locked loop circuit, which is used in a clock multiplier unit in the first mode, and in a clock recovery circuit in the second mode. |
