Pluggable module

A pluggable module comprising a housing having a first end and second end, an edge connector disposed at the first end, an F-type coaxial connector at the second end and a release lever including a stamped body that is symmetrical about a centerline bisecting the length of the body. The pluggable module comprises a miniature balun disposed within the module for converting between a single-ended input to a differential load.

Transceiver module with flex circuit

A transceiver assembly is provided that includes a transceiver housing having first end, having a connector and an opposite second end having a passage in communication with a printed circuit board mounted in the housing. A peripheral connector having a first end and opposite second end includes a receptacle opening at the second end. A flex circuit is disposed between the first end of the peripheral connector and the second end of the transceiver housing. The peripheral connector is capable of being displaced with respect to the transceiver housing via the flex circuit.

The present invention provides a multi-channel transceiver module comprising a unitary housing having a first channel body and a second channel body. Each channel body includes a male plug end and a receptacle plug end. A bridge member is provided for joining the first and second bodies. The bridge members disposed at the receptacle end. A gap is provided between the plug ends of each channel body. The gap extends from each plug end to the bridge member to partially divide each channel so that each plug end is insertable within a separate receptacle cage.

Multi-channel tranceiver module

A receptacle assembly is provided having a gasket interposed between a heat sink and the receptacle, in order to provide EMI shielding and limit leakage from an opening in the receptacle that allows the heat sink to engage an electronic module inserted in the receptacle cavity. The heat sink may have a groove in which the gasket is mounted and upon mounting the heat sink to the receptacle, the gasket surrounds the opening in the receptacle and provides a resilient shield to maintain a seal during movement of the heat sink due to insertion of the electronic module within the receptacle.

The invention relates to an interface module, such as a Giga-Bit Interface Converter module, provided to mate within a host device chassis where, at the rear of the mounting slot, a first connector engages a host socket of the host device. According to the invention, the first connector include sequential mating contact traces on a contact beam of a substrate such that when the module is inserted into the corresponding host socket, certain contacts are connected in a pre-defined sequence such that a first set of contacts electrically engages prior to a second set of contacts which electrically engages prior to a third set of contacts. In further accord with the present invention, the first set of contacts includes grounding contacts, the second set includes contacts for powering the substrate and the third set includes signal contacts. An advantage of this sequence is that the GBIC is grounded before it is powered and powered before it begins passing signals thus eliminating the damage to the GBIC encountered under the GBIC-to-host contact sequence given in the prior art GBIC specification.

A system and a method are provided for conversion of a display of a computer monitor from VGA signals to NTSC signals for display on a television screen. The system implements a circuit which reduces flicker in the output of the NTSC screen. The system includes an input device for inputting a signal in an identifiable mode to stored non-interlaced data relating to the VGA image signals in field memory areas. The VGA image signals are converted in the field memory areas stored to interlaced NTSC image signals. A controller controls the storage and conversion of the VGA signals to NTSC image signals in field memory areas to produce an output.

VGA to NTSC converter and a method for converting VGA image to NTSC

An adapter for performing bi-directional data transfers between a SCSI bus, which transfers data using a parallel format, and a serial transfer medium, which transfers data using a serial format and being connected to a serial device. The adapter bi-directionally transfers SCSI data between itself and the SCSI bus. In addition, the adapter bi-directionally converts between SCSI formatted data and serially formatted data. Furthermore, the adapter bi-directionally transfers serially formatted data between itself and the serial transfer medium.

Method and apparatus for transferring data from SCSI bus to serial

A method and apparatus electrically disconnects termination on a differential transmission bus. A switchable impedance matching termination apparatus is provided including a terminating resistor network for terminating at least one pair of a plurality of differential signal line pairs. An enabling signal input is also provided. Further, the invention has a first signal network interconnected between the enabling signal input and the terminating resistor network. Also provided is a second signal network interconnected between the enabling signal input and the terminating network wherein the first and second signal networks are responsive to the signal. The response is designed to terminate the at least one pair of the plurality of differential signal line pairs. A method is also provided for disconnecting terminating resistors on a device having a differential transmission line.

Switchable differential terminator

An inactive state termination tester for determining the number of terminators connected to a bus when the bus is inactive. The termination tester monitors the bus for determining when it is inactive. During the periods of bus inactivity, the termination tester senses the bus to determine the number of terminators connected to the bus. The termination tester then displays how many terminators were detected and/or generates a signal to either enable or disable, respectively, a controllable bus terminator depending on if there are not enough or too many terminators determined to be connected to the bus. Furthermore, the termination tester maintains the controllable bus terminator in the proper enable or disabled mode whenever bus activity resumes.
