Abstract: A multi-function interface includes a digital interface module and a configurable output impedance module. The digital interface module is operably coupled to pass a first type of input signal when the multi-function interface is in a first mode and operably coupled to pass a second type of input signal when the multi-function interface is in a second mode. The configurable output impedance module is operably coupled to the digital interface to provide a first output impedance when the multi-function interface is in the first mode and to provide a second output impedance when the multi-function interface is in the second mode.

Abstract: A voltage regulator may include one or more features for generating high PSRR. For example, source follower devices may be included in the voltage regulator for providing current sources for the output voltage nodes. The source followers may be sensitive to power supply noise at the gate terminal. Filters are included on the gate terminals to filter the power supply noise, thus reducing the noise at the gate terminals. As another example, the voltage regulator may employ current sources on the output voltage nodes which produce current inversely proportional to the current drawn by the load. In one embodiment, the voltage regulator may include a power control circuit used to provide overvoltage protection during power up. The power control circuit provides a voltage during power up, and ceases providing the voltage after a time interval so that the circuit may operate.

The configurable output impedance module is coupled to the configurable driver module to provide a 1st output impedance of the interface when the interface is in the 1st mode and to provide a 2nd output impedance when the interface is in the 2nd mode.

Abstract: A receiver multi-protocol interface includes a wide bandwidth amplifier, a data sampling module, and a clocking module. The wide bandwidth amplifier is operably coupled to amplify a 1st formatted input signal or to amplify a 2nd formatted input signal to produce an amplified input signal. The data sampling module is operably coupled to convert the amplified input signal into a 1st data stream in accordance with at least one 1st sampling clock signal when the interface is configured in the 1st mode and to convert the amplified input signal into a 2nd data stream in accordance with at least a 2nd sampling clock signal when the interface is in a 2nd mode. The clocking module is operably coupled to generate the 1st sampling clock signals from a reference clock when the multi-protocol interface is in a 1st operational mode and generates the 2nd sampling clock signals based on the reference clock when the interface is in the 2nd operational mode.
