Serial digital interface

Abstract: A wireless radio for wireless networking communication systems includes a radio frequency (RF) transceiver integrated circuit (IC) and a baseband digital signal processing (DSP) IC. A bidirectional serial digital interface couples data between the RF transceiver IC and the DSP IC to provide a high data rate and low noise. The bidirectional serial digital interface includes a first serial data connection and a second serial data connection. In one embodiment, the RF transceiver IC has a single bit sigma delta A/D modulator to convert an analog signal into a first serial digital bit stream for communication over the first serial data connection. In one embodiment, the DSP IC has a single bit sigma delta digital modulator to generate a second serial digital bit stream for communication over the second serial data connection.

Abstract: A small form factor optical transceiver module (100) is provided that includes a housing within which are disposed an optical transmitter (103) and an optical receiver (102). A controller IC (110) is also disposed in the housing and includes a serial digital interface (121) configured to facilitate communication between the controller IC (110) and a host. Among other things, the serial digital interface enables access to onboard digital diagnostics while substantially conforming with the standardized packaging, footprint, and form factor of a standardized optical transceiver module. Further, the use of memory map locations in the controller IC (110) enables the implementation of various types of host accessible diagnostic and other functionalities in the optical transceiver module (100).

Abstract: This paper presents an innovative system architecture that leverages the fast switching speed, nonlinear output response, and high optical flux threshold of the Grating Light Valve (GLV) * technology to create high-performance displays. This architecture creates a high-resolution projected image by optically scanning a linear array of GLV pixels, requiring about two thousand times fewer pixels than a 2-D panel and about one thousand times lower bandwidth than a scanned-spot approach for HDTV display. A 1080p projection display prototype based on this architecture has been developed, which displays 1920 x 1080 resolution, 30-bit color (10 bit/channel RGB) and up to 120-Hz refresh. The system receives 1080p video data at 24 or 30 frames/sec via a standard SMPTE 292M serial digital interface. While leveraging many traditional realtime video-processing techniques, several processing steps that are unique to the scanned linear architecture have been developed, including display mapping, data calibration, row/column transpose, frame rate multiply, and frame dither/refresh. The system is synchronous at 74.25 MHz.

Abstract: A digital data transmission apparatus which can suitably route and transmit to a desired apparatus two types of digital data, that is, digital data of a serial digital interface (SDI) format and a serial digital data interface (SDDI) format having a partially common format to the SDI format even if they are mixed, the digital data transmission apparatus having a first routing apparatus (20, 20A) having a first signal supplier (102) for supplying the data of a first transmission packet of the SDI format; a second signal supplying means (104) for supplying data of a second transmission packet of the SDDI format having a common control data portion to that of the SDI format and having the same data length; a first input terminal receiving the data of the first transmission packet; and a second input terminal receiving the data of the second transmission packet and outputs the first input data supplied to the first input terminal from the first output terminal and outputs the second data supplied to the second input terminal from the second output terminal based on the set routing information.
