  • Patent number: 8796840
    Abstract: A semiconductor assembly includes a first subassembly comprising a heat sink and a first patterned polymer layer disposed on a surface of the heat sink to define an exposed portion of the first surface. The exposed portion of the first surface extends radially inward along the heat sink surface from the first layer. The subassembly also includes a second patterned polymer layer disposed on a radially outer portion of the first patterned polymer layer. The first and second layers define a cell for accommodating a power semiconductor die. Solder material is disposed on the exposed portion of the heat sink surface and in the cell. A power semiconductor die is located within the cell on a radially inward portion of the first layer and thermally coupled to the heat sink by the solder material.

  • Patent number: 8768166
    Abstract: Adaptive power setting techniques for optical transceivers are provided. Optical signals are received at a first optical transceiver device that are transmitted from a second optical transceiver device. A receive power of the optical signals received at the first optical transceiver device from the second optical transceiver device is determined. A characteristic of optical signals transmitted by the first optical transceiver device to the second optical transceiver device is modulated to indicate to the second optical transceiver device a disparity of the receive power with respect to a target receive power level at the first optical transceiver device. Conversely, the first optical transceiver device adjusts a power level of optical signals transmitted by the first optical transceiver device to the second optical transceiver device based on a characteristic of the optical signals received at the first optical transceiver device.

  • Patent number: 8713237
    Abstract: An apparatus includes a transceiver device mounted on a printed circuit board and configured to selectively transmit and receive signals at a first data rate or signals at a second data rate. An X2 form factor pluggable connector disposed at one end of the printed circuit board includes first and second pins that respectively convey signals at the first and second data rates between the transceiver device and a system device. A port device disposed at an opposite end of the printed circuit board conveys signals between the transceiver device and a network device. A management circuit determines which of the first and second data rates is selected based on transmissions between the system device and the network device and controls the transceiver device to transmit and receive signal at the first data rate via the first pins and at the second data rate via the second pins.
