Abstract: An orthogonal frequency division multiplexing (OFDM) communication system includes a first interface having a first cable coupler to couple to a first end of a coaxial cable, and a first plurality of signal pathways coupled to the first cable coupler. Each signal pathway of the first plurality includes a physical (PHY) layer component and a radio frequency (RF) front end coupled to the PHY layer component. The system further includes a second interface having a second cable coupler to couple to a second end of a coaxial cable, and a second plurality of signal pathways coupled to the second cable coupler. Each signal pathway of the second plurality corresponds to a signal pathway of the first plurality and includes a PHY layer component and an RF front end coupled to the PHY layer component.

Abstract: An oscillator includes a compensated current source that adjusts an output current based on process, supply voltage, and temperature (“PVT”) variations of an integrated circuit device. The oscillator generates an output signal having a frequency based, in part, on the output current of the compensated current source. Accordingly, the output signal has a relatively low sensitivity to PVT variations.
