Abstract: Technologies for transmitters with differential signal cross point voltage control are described. One transmitter circuit includes a differential driver circuit to generate a differential output signal. The differential driver circuit includes a programmable phase distribution to adjust a differential cross-point ratio of the differential driver circuit. The differential driver circuit includes a plurality of voltage-mode drivers, each voltage-mode driver comprises a pull-up transistor, a pull-down transistor, and a pre-driver with a programmable phase that is individually controlled for each voltage-mode driver such that the plurality of voltage-mode drivers collectively adjust the differential cross-point ratio.

Abstract: An optical out-coupler unit for out-coupling light from a waveguide, comprising a substrate having a planar top surface, a waveguide arranged on the top surface of the substrate and having a facet, a reflective surface, wherein the reflective surface is arranged spaced apart from the facet and opposing the facet, wherein the reflective surface is inclined with respect to a normal to the top surface of the substrate by more than 45°. The optical out-coupler may be part of a photonic integrated chip (PIC).

Abstract: The presently disclosed subject matter provides compositions, kits, and methods comprising imaging agents that can detect Programmed Cell Death Ligand 1 (PD-L1). The presently disclosed imaging agents can be used to detect diseases and disorders, such as cancer, infection, and inflammation, in a subject.

Abstract: Push-pull integrated circuit output drivers may interfere with communication by other entities on a bus when an integrated circuit is powered down. When there is no power and/or when the bonding pad is externally driven above the internal supply voltage, the substrate/body/well of the p-channel field effect transistor (PFET) of the output driver is biased to prevent its drain diode from becoming forward biased thereby preventing interference with communication on the bus. Also, when there is no power, driver is powered down or pull up is disabled, the gate of the driver PFET is driven to a voltage that ensures the driver PFET remains off when the bonding pad is externally driven above the internal supply voltage.

Abstract: A device is disclosed for monitoring power from a laser diode. The device includes a substrate having a top surface and a first facet perpendicular to the top surface through which light enters the substrate. The device further includes a second facet onto which light that has entered the substrate through the first facet along an optical axis that is non-normal to the first facet is incident. The device further includes a photodiode fabricated on the top surface of the substrate for measuring an intensity of the light that enters the first facet of the substrate along the optical axis that is non-normal to the first facet. The light that has entered the substrate through the first facet along the optical axis that is non-normal to the first facet is reflected by the second facet toward a photoactive region of the photodiode.

Abstract: A method and system for synchronous page addressing in a data packet switch is provided. Within the packet switch, separate devices are responsible for storing a portion of a received data packet, and thus a view of used memory addresses seen by one device matches that seen by the others. Each device uses the same order of memory addresses to write data so that bytes of data are stored as a linked-list of pages. Maintaining the same sequence of page requests and sequence of free-page addresses to which to write these pages ensures consistent addressing of the portions of the data packet.

Abstract: A system and method for buffering data packets in a data network device having a DRAM buffer are presented. When writing packets, the buffering system separates available memory channels into two groups corresponding to ingress and egress data. Based on the source of the data packets, data pages from the data packets are assigned to channels from either the ingress or egress group. Non-conflicting sets of addresses, called cachelines, are requested on each memory channel, and the data pages are evenly distributed over the assigned channels before being mapped to a cacheline. The number of read transactions currently being monitored by the system is controlled in order to reduce random packet read conflicts. Additionally, write and read transactions are grouped by an arbitration unit prior to being sent to the DRAM controller.

Abstract: A system for streaming incoming data packets into a buffer memory is presented. The system may receive incoming data packets over a variety of interfaces and separate the data packet into a header page and one or more data page. The system may interface with a header processor and send header pages to the header processor to be modified. Data pages from the incoming data packets are streamed to a central staging memory, allowing the use of a simple first-in-first-out (FIFO) buffer. The system may receive modified headers from the header processor and provide multiple copies of data packets for multicast or sampling purposes. Data packet copies may then be written to an external memory buffer over one or more external memory channels. The system may also provide an error recovery process to account for corrupt data packets streamed to the external memory buffer.
