This Product Selection Guide contains information to help select products in the Delay Lines category on DigiKey.com
Products in the clock delay line family are digital devices used to introduce a time delay into a digital signal, such that signal transitions presented to a device’s input are replicated at the output after some known period of time. They are often used in high-speed digital systems to correct or compensate for variations in signal propagation times between different signal paths. Devices are available to generate delays of fixed, selectable, or variable duration.
SelectionCharacteristics
Number of Taps/Steps: The number of points along the delay line where a signal can be accessed; the granularity of delay length adjustment.
Function: Describes the main function or usage of the circuit.
Delay to 1st Tap: The nominal time delay from input to the first (shortest delay) output; the minimum time delay the device can produce.
Tap Increment: The nominal difference in delay length between functionally-adjacent outputs from the delay line.
Available Total Delays: End-to-end delay line length (range for variable-delay devices)
Number of Independent Delays: Indicates the number of independent delays per device function.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
