Abstract: Systems and methods are provided that may be implemented in-situ and on-chip to capture a digital signal eye of a serial transmit signal produced by a transmitter circuit of integrated SerDes PHY transceiver circuitry. In one example, a serial transmit signal produced by a transmitter side circuit of an integrated SerDes PHY transceiver circuit may be looped back on chip to the receiver side circuit of the same SerDes PHY transceiver circuit such that an integrated digital eye monitor circuit of the SerDes receiver circuit may capture the digital eye of the serial transmit signal of the same SerDes PHY circuit. In another example, a digital eye monitor circuit may be integrated on the transmitter side of an integrated SerDes PHY transceiver circuit such that a serial transmit signal produced by the transmitter side circuit of may be captured on-chip.

Abstract: A modular vacuum drainage system is provided which facilitates quick and easy installation in a building. The system includes a vacuum central housed in an enclosure and having interface connections located adjacent to a periphery of the enclosure to allow immediate access thereto. The vacuum central is sized to fit through standard doorway sizes, and is preferably housed in a soundproof enclosure so that the vacuum central may be installed in a room without requiring a separate mechanical room. The enclosure may be decorated to match the decor of the office, thereby providing an aesthetically pleasing appearance. A modular plumbing fixture is also provided which may be pre-fabricated off-site. The modular plumbing fixture is provided in a housing and has water and vacuum pipe inlets accessible from outside of the housing to facilitate connection to the vacuum central.
