Abstract:
1. A transceiver module, comprising: a connector suitable for receiving a plurality of voltage sources including an IC voltage from a power supply, the plurality of voltage sources each contributing noise to the IC voltage; a voltage filter in communication with the connector, the voltage filter having an input voltage and an output voltage, the input voltage being the IC voltage, and the output voltage being a filtered voltage that is less than the IC voltage, the filtered voltage determined by a voltage drop across the voltage filter, wherein the voltage filter filters the noise contributed by the plurality of voltage sources including the IC voltage from the IC voltage; and a signal processing IC in communication with the voltage filter, the signal processing IC having a Vdd selected to account for the voltage drop of the voltage filter such that the signal processing IC is configured to be powered by the filtered voltage, and the signal processing IC being operable at the filtered voltage.
