Data-dependent jitter (DDJ) is a specific class of timing jitter. In particular, it is a form of deterministic jitter which is correlated with the sequence of bits in the data stream. It is also a form of ISI .
Deterministic jitter has a known non-normal distribution. Deterministic jitter can either be correlated to the data stream (data-dependent jitter) or uncorrelated to the data stream (bounded uncorrelated jitter). Examples of data-dependent jitter are duty-cycle dependent jitter (also known as duty-cycle distortion) and intersymbol interference.
The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.
Deterministic Networking (DetNet) is an effort by the IETF DetNet Working Group to study implementation of deterministic data paths for real-time applications with extremely low data loss rates, packet delay variation (jitter), and bounded latency, such as audio and video streaming, industrial automation, and vehicle control.
The FS5000 Jitterlyzer performs physical layer serial bus jitter evaluation. It can inject controlled jitter and measure the characteristics of incoming jitter. When teamed with a logic analyzer or protocol analyzer, it can correlate these measurements with protocol analysis. Physical-layer tests can be performed while the system under test is ...
Benefits of Assisted Living for Wheelchair Users. Compared to independent living, assisted living can provide a wider breadth of support. These services provide a safe and comfortable atmosphere ...
The different AVB/TSN standards documents specified by IEEE 802.1 can be grouped into three basic key component categories that are required for a complete real-time communication solution based on switched Ethernet networks with deterministic quality of service (QoS) for point-to-point connections. Each and every standard specification can be ...
Millions of Americans should prepare for an Arctic blast that will blanket much of the country in below-freezing temperatures over the next several days. Frigid conditions are expected over a ...
