AD9505KP - Digitally Programmable Pulse-Edge Delay | Analog Devices
MPN： AD9505KP ✗ 停產AD9505KP 概覽
A pulse-edge delay vernier is a timing-control integrated circuit used to shift the transition of a pulse by a programmable or controlled amount. These devices belong to the broader clock and timing hierarchy, alongside clock generators, phase-locked loops, frequency synthesizers, delay lines, and timing controllers. The AD9505KP is intended for systems where edge placement, phase alignment, or calibration must be adjusted while maintaining a fixed circuit footprint.
The verified listing describes the AD9505KP as a digitally programmable pulse-edge delay vernier and identifies the package as 28-pin PLCC. Because the supplied snippets do not expose the detailed electrical timing range, input frequency, output frequency, propagation delay, logic levels, control interface, temperature range, or absolute maximum ratings, those values must be confirmed from the manufacturer datasheet before design release. The package information and device function are suitable for initial component identification, but they do not establish a complete timing specification.
AD9505KP devices are associated with clock and timing applications, including digital interface timing, phase adjustment, synchronization networks, clock distribution, instrumentation, and communication equipment. The part can be useful when a fixed-frequency clock requires edge repositioning or where multiple signals must be aligned within a system. The exact implementation depends on the supported logic levels, delay range, control format, and timing specifications in the official documentation.
For PCB design, confirm the 28-lead PLCC footprint, pin orientation, exposed-contact requirements, and recommended decoupling against the Analog Devices datasheet. Do not infer a replacement part solely from package similarity; timing range, control protocol, logic compatibility, and pin function must match. This page combines verified distributor identification, package details, source links, and explicit data gaps rather than estimating undocumented parameters.

典型應用
AD9505KP 適用於 6 應用s: Clock Synchronization, Phase-Aligned Data Paths, Clock Distribution, Synchronous Communication Equipment, Test and Measurement Timing, Digital Interface Alignment.
Clock Synchronization
The AD9505KP is a timing-control IC that can be evaluated for clock synchronization because its verified function is a digitally programmable pulse-edge delay vernier. In a synchronization system, it would be used where an incoming pulse must be shifted relative to another reference edge. The practical benefit is adjustable edge placement, but the exact delay range, input frequency, jitter, and control method are not included in the verified snippets and must be confirmed from the manufacturer datasheet before implementation.
推薦
Phase-Aligned Data Paths
AD9505KP can be considered for phase alignment in digital data paths where a pulse transition must be repositioned relative to a sampling or forwarding clock. Its identified pulse-edge delay function is relevant to interfaces that require controlled phase relationships. However, the supplied evidence does not confirm the supported data rate, output logic levels, delay resolution, or package pin mapping, so a board design must wait for verified timing and electrical specifications.
推薦
Clock Distribution
The AD9505KP may fit clock-distribution architectures that require edge correction, calibration, or phase adjustment between timing domains. It would typically sit near a clock buffer or interface where the pulse transition must be adjusted without changing the system clock frequency. The verified listings establish the timing-function and package identity, but they do not provide the frequency range or propagation-delay limits needed to confirm a production clock-tree design.
推薦
Synchronous Communication Equipment
AD9505KP is applicable to communication equipment in which pulse-edge timing affects alignment between transmitter, receiver, or control circuits. The device’s programmable-delay concept can support edge placement in systems with multiple related clocks or serialized data transitions. Actual suitability depends on the documented input bandwidth, output timing behavior, control interface, and supply requirements, none of which are supplied by the verified search snippets.
推薦
Test and Measurement Timing
The AD9505KP can be evaluated for test and measurement systems requiring programmable edge placement, calibration, or synchronization between stimulus and response clocks. The verified component description supports timing-adjustment use cases, while the 28-pin PLCC package facilitates a dedicated timing section on a larger instrument board. Verification must include the device’s timing resolution, input range, jitter, and logic compatibility before selecting it for precision instrumentation.
推薦
Digital Interface Alignment
AD9505KP may be used in digital interfaces where a control, data, or latch edge must be aligned with a reference clock. A programmable pulse-edge delay can reduce timing uncertainty by shifting one transition relative to another, subject to the device’s documented resolution and operating limits. The supplied search data does not establish whether the part supports the required logic standard, voltage, frequency, or control protocol, so these requirements must be checked in the datasheet.

主要差異化特點
- Dedicated digitally programmable pulse-edge delay function (對比Generic clock-generation or delay IC)

- Commercial-grade component identification (對比Automotive or extended-temperature replacement)
設計說明
Do not select AD9505KP from package identity alone. The verified data confirms a 28-pin PLCC package and a pulse-edge delay function, but it does not provide the pin table, supply voltage, timing range, or control interface. Before placing the part, compare the official AD9505KP pinout and electrical tables with the existing board. A same-package device with different pin functions can cause timing failure or damage adjacent circuitry.
Use the verified 28-pin PLCC footprint as the starting point for layout, but confirm package dimensions, lead pitch, pin-one orientation, and recommended solder-pad geometry from the official datasheet. Route the timing input, timing output, control signals, and supply connections with short paths and maintain a continuous return path. Do not infer exposed-contact or thermal requirements from the package code alone.
AD9505KP supply requirements are not included in the verified snippets. Before adding decoupling, determine the supported supply voltage, current consumption, and sequencing limits from the manufacturer datasheet. Follow the documented bypass-capacitor values and placement recommendations; generic ceramic capacitors or bulk capacitance should not be substituted without checking stability and timing performance.
Treat pulse-edge delay as a timing-sensitive signal path. Keep the device close to the relevant clock or data interface, minimize stubs and unnecessary loop area, and use controlled-impedance routing where the design operates at higher signal rates. Validate edge quality, jitter, and delay accuracy on the assembled board because the verified data does not provide those electrical limits.
合規資訊
The supplied snippets identify a commercial-grade Analog Devices component but do not provide RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed from current manufacturer documentation or distributor records.
