propagation delay

[‚präp·ə′gā·shən di‚lā]
(electronics)
The time required for a signal to pass through a given complete operating circuit; it is generally of the order of nanoseconds, and is of extreme importance in computer circuits.

propagation delay

The time it takes to transmit a signal from one place to another. Propagation delay is dependent solely on distance and two thirds the speed of light. Signals going through a wire or fiber generally travel at two thirds the speed of light. Contrast with nodal processing delay.

Reduces solution size and weight: Features the industry's fastest propagation delays at 15ns, faster rise and fall times at 7ns, allowing the system to switch efficiently at high frequencies.
Thus, the propagation delay can be reduced as shown in Equation 1:
Normally there is an option to place a PLL before the clock tree to achieve zero clock propagation delay through the clock network.
FIGURE 3b depicts in-out signals plus associated propagation delay (maximum delay between input and output signal changes) timing specification.
This technique allows more flexibility in total propagation delay along the bus, but introduces additional complexities.
8,976,060 -- RF Chirp Signal Propagation Delay Measurement -- This is the first patent supporting Digi's groundbreaking Punch2 Technology in the Digi XLR PRO family of RF radios and is the first of nine patents pending in connection with the product.
Traditional magnetic rotary position sensor ICs suffer from a propagation delay (typically 100-200os) as they convert raw measurements of magnetic field strength at their embedded magnetic elements into digital angle measurements.
A comparison of equations in Tables 1 and 2 reveals that the loaded or effective characteristics impedance (Zo') and propagation delay (Tpd') are related to the unloaded--also called intrinsic or natural--impedance (Zo) and propagation delay (Tpd) (1, 11) by:
Availability of dark fiber, network topology, link distance, signal propagation delay, Fibre Channel buffer credits and host applications tolerances to latency are among the items that storage networking engineers must consider.
Maximum propagation delay time is rated at 150ns, and maximum propagation delay skew at 80ns.
Maximum propagation delay time and propagation delay skew are guaranteed within the defined operation temperature range (up to 110 degrees Centigrade), making it possible to reduce dead time in the inverter circuit, which can secure higher operating efficiency.
