The TMDS output has a built in level shifting re-driver supporting Digital Video Interface (DVI) 1.0 and High Definition Multimedia Interface (HDMI) 1.4b standards. The SN75DP139 is specified up to a maximum data rate of 3.4Gbps, supporting resolutions greater then 1920x1200 or HDTV 12 bit color depth at 1080p (progressive scan). SN75DP139 is compliant with the HDMI 1.4b specifications and supports optional protocol enhancements such as 3D graphics at resolutions demanding a pixel rate up to 340MHz. An integrated Active I2C buffer isolates the capacitive loading of the source system from that of the sink and interconnecting cable. This isolation improves overall signal integrity of the system and allows for considerable design margin within the source system for DVI / HDMI compliance testing.

  • Serial ATA Interface
    Serial ATA Interface Frank R. Chu Senior Engineer Hitachi Global Storage Technologies June 2003 Why do we need a new interface? Limitations of parallel ATA Serial ATA was designed to overcome a number of limitations of parallel ATA. The most significant limitation of parallel ATA is the difficulty in increasing the data rate beyond 100MB/s. Parallel ATA uses a single-ended signaling system that is prone to induced noise. Increasing the parallel data rate beyond 100 MB/s would require a new signaling system that would not be backward compatible with existing systems. Desktop HDDs can be expected to outrun the 100 Mbytes/sec data rate in the next few years so a new system is needed. An additional limitation is that parallel ATA uses 5V signaling levels and upcoming silicon microelectronic processes are not compatible with 5V signaling. Serial ATA overcomes these issues by moving to 250mV differential signaling method. Differential signaling rejects induced noise. The 250mV differential signal level is compatible with future microelectronic fabrication processes. Parallel ATA Topology Serial ATA Topology Parallel ATA Topology Serial ATA Topology Operating system Operating System Serial ATA ATA Application 1 Application 1 Standard Adapter adapter Disk Driver Application 2 Driver Application 2 Drive Disk Application 3 Disk Disk Application 3 Drive drive drive Forecasts Indicate ATA Dominance ATA is the dominant HDD interface in the industry. The ATA interface market is expected to be approximately 190 million units in 2003, accounting for about 90% of all HDDs shipped, according to International Data Corporations (IDC) 2002/03 forecasts. By 2006, IDC projects ATA unit shipments will increase to beyond 310 million and continue to account for 90% of all HDDs shipments.

This note describes methods for distributing high-speed communications signals to different destinations using LVDS signaling. Low-voltage differential signaling (LVDS) is well-suited for a variety of applications, including clock distribution and point-to-multipoint signal distribution. This note describes methods for distributing high- speed signals to different destinations. Clock distribution is of great importance in digital systems where different subsystems are required to work with the same clock reference. For example, the DSP section of a basestation must, in most cases, be synchronized to the radio-frequency signal processing section, which is where phase-locked loops (PLLs) produce the required local oscillator frequencies and where analog-to-digital converters are locked to the central clock reference. Also, when working with applications that include radio receivers, the clock (and the signals) must be distributed with the lowest possible emission levels to avoid interfering with low-level signal paths.

  • Comparison of RS-485 Differential-Mode Noise Immunity
    Application Report SLLA322–November 2011 Comparison of Differential-Mode Noise Immunity of RS-485 Receivers With 3.3-V Supply Clark Kinnaird ........................................................................................................ Industrial Interface ABSTRACT RS-485 is a widely used standard for industrial communication due to its simplicity and suitability for use in high-noise environments on long cables. Inherent in the standard are balanced signal drivers and receivers, which use differential signaling to reject common-mode noise. Receiver hysteresis is commonly used to ensure glitch-free reception even when differential noise is present. This application report compares the noise immunity of the SN65HVD37 to similar devices available from competitors.

  • Differential Signaling Doesn't Require Differential
    Article for Printed Circuit Design By Lee W. Ritchey, 3Com Corporation Differential Signaling Doesn’t Require Differential Impedance Or, How to Design a Differential Signaling Circuit That title may seem like a complete contradiction to the “wisdom” written in many design documents describing how to route differential pair signals. It is ---- and that is just what its intent is. Now that your attention has been caught, let’s look at differential signaling. Virtually all design rules in common use require designers to provide a specified differential impedance between pairs of signals involved in differential signaling circuits such as differential ECL or LVDS (Low Voltage Differential Signaling). As a result, much effort is consumed trying to decide on PCB geometries that will provide the desired impedance and an equal amount of effort trying to lay out the traces and build the PCB. On top of this, much time is spent trying to accurately measure the differential impedance. As it turns out, differential impedance doesn’t play a role in this form of signaling and is not necessary. How it was decided to impose this condition on this type of signaling is a mystery. It probably happened because the word differential is in the title. In any case, as will be seen in the following explanation of how this signaling works, other design considerations are more important. First, it is useful to understand the problem that differential signaling was designed to solve. Differential signaling is designed to transmit logic signals between two boxes or units that have logic grounds offset from each other by an amount too large for single ended logic signals to function correctly.
