Abstract
An integrated circuit for use at a reduced Vdd voltage. An integrated circuit is designed and implemented such that it is usable at a voltage less than an industry standard Vdd voltage. The integrated circuit may include a voltage filter that may either be implemented on the integrated circuit or external to the integrated circuit. The voltage filter receives an industry standard IC voltage and produces a filtered voltage that is that some value below the industry standard IC voltage. The voltage filter also removes noise from the industry standard IC voltage. The integrated circuit includes signal processing circuitry that is designed and implemented to improve signal quality and to operate at the filtered voltage.
Claims10
A transceiver module usable in fiber-optic communication applications, the transceiver module comprising:
- a receiver optical subassembly configured to receive optical signals;
- a transmitter optical subassembly configured to transmit optical signals;
- a connector adapted to couple the transceiver to an IC voltage associated with an external power supply;
- a voltage filter adapted to receive the IC voltage from the external power supply and generate a filtered voltage at a voltage level less than the IC voltage;
- and
- a signal processing integrated circuit powered by the filtered voltage, the signal processing integrated circuit designed to be operated at the voltage level of the filtered voltage.
