AD9500BP - 10 ps Digital Delay Generator | Analog Devices
MPN: AD9500BP ✗ پایان تولیدAD9500BP نمای کلی
A digitally programmable delay generator belongs to the clock-and-timing IC hierarchy, where timing-control circuits align or offset events relative to an external reference. The AD9500BP is intended for precision systems where propagation delay must be adjustable while preserving repeatable differential signaling and separate control paths for triggering and reset.
The core feature set includes an 8-bit programmable delay code, 10 ps resolution, and a 10 ns full-scale delay range. Fully differential inputs support single-ended or differential ECL drive, while the complementary ECL output includes a Q/R parallel output option for reset-timing implementations. Separate trigger and reset inputs provide distinct event-control functions rather than combining their roles.
The AD9500BP supports low-power operation and is available in versions compliant with MIL-STD-883, although the exact grade, revision, and qualification status of this specific ordering code require confirmation from current Analog Devices documentation. Its timing characteristics are suited to ATE pulse deskewing, arbitrary waveform generation, and high-stability timing systems where programmable delay correction improves channel-to-channel alignment.
Use the device in instrumentation, automatic test equipment, pulse-generation systems, and digital timing subsystems. The programmable delay permits firmware or calibration hardware to compensate for cable, fixture, propagation, and channel variations. Differential inputs and ECL outputs can simplify interface design in high-speed test environments, provided the external logic levels and termination requirements are matched.
The primary design consideration is system calibration: the external clock, trigger, reset, control-code timing, and output termination must be treated as one timing chain. Engineers should verify package pinout, control polarity, propagation-delay limits, and supply requirements against the current manufacturer datasheet before layout or production use.

کاربردهای معمول
AD9500BP مناسب است برای 6 کاربردs: ATE Pulse Deskewing, Arbitrary Waveform Generator Timing, High-Stability Timing Systems, Pulse Generator Systems, Digital Timing Calibration, Instrumentation and Test Modules.
ATE Pulse Deskewing
AD9500BP fits automatic test equipment where individual channels need programmable timing alignment. Its 8-bit digital control code can represent a delay from the selected code range, with the verified family data specifying 10 ps resolution and a 10 ns full-scale range. That range is useful for compensating fixture, cable, propagation, and channel-to-channel offsets without changing the analog delay network. Differential inputs and complementary ECL outputs help integrate the device into timing-intensive test systems, while separate trigger and reset paths support deterministic event sequencing. The engineer should calibrate the code-to-delay relationship in the final fixture and verify the complete timing budget against the AD9500 datasheet.

Arbitrary Waveform Generator Timing
AD9500BP can provide programmable timing skew in arbitrary waveform generation systems where a fixed output delay would limit calibration. The 10 ps resolution and 10 ns full-scale range allow the timing command to be adjusted during instrument setup or calibration. Its 8-bit interface makes the delay state suitable for a digital control path, while the differential input and ECL output structure supports compatible high-speed logic environments. In a waveform instrument, the device is best treated as a timing-control element rather than a waveform synthesizer: the external DAC, memory, and clock circuitry determine the waveform, while AD9500BP aligns the launch and trigger timing. Verify settling, jitter, and output-delay limits in the final instrument.
پیشنهادی
High-Stability Timing Systems
AD9500BP is applicable to high-stability timing systems that require repeatable, adjustable event positioning. The verified 10 ps resolution gives a fine control increment, and the 10 ns full-scale range provides enough span for deskewing and calibration offsets. Separate trigger and reset inputs can help preserve distinct control semantics when the surrounding system needs event qualification or reset timing. Differential input support allows the timing source to be connected through ECL-compatible single-ended or differential drive, while the complementary ECL output supports downstream timing distribution. Stability must be evaluated against the system clock, power supply, temperature, and output loading rather than inferred from resolution alone.
پیشنهادی
Pulse Generator Systems
AD9500BP can support pulse generators where trigger-to-output timing must be calibrated rather than fixed. The 8-bit delay code allows an instrument controller to compensate for differing cable lengths, probe interfaces, or channel delays. Its complementary ECL output and Q/R parallel output option are particularly relevant to circuits that need both normal and reset timing behavior. The separate trigger and reset inputs help avoid combining mutually different control functions on one input. For a complete pulse generator, pair the AD9500BP with an external clock source, output driver, and appropriate ECL termination. Validate output amplitude, edge rate, jitter, and propagation delay using the current Analog Devices documentation.

Digital Timing Calibration
AD9500BP is suitable for digital timing calibration where multiple paths or channels must be aligned to a common event. The programmable delay can represent calibration offsets directly through the 8-bit code, avoiding a large collection of fixed delay components. The 10 ns full-scale range is suitable for board-level and fixture-level offset compensation, while the 10 ps resolution supports finer adjustment. In a calibration loop, the host or controller can measure an event, calculate a code, write the delay setting, and verify the corrected timing. The device does not remove the need for a stable reference, controlled termination, and an output measurement path; those system errors must be characterized separately.
پیشنهادی
Instrumentation and Test Modules
AD9500BP can be used in instrumentation modules requiring controlled timing relationships between trigger, reset, and delayed outputs. Its low mW-class power indication is useful when designing compact test and measurement equipment, while the 28-pin J-lead LCC package supports a ceramic surface-mount implementation. Differential inputs and ECL outputs can reduce sensitivity to common-mode noise when the board is otherwise properly terminated and referenced. The programmer must preserve setup and hold timing around the 8-bit control code, and the system must account for reset and trigger propagation. Because the supplied data does not include exact supply, temperature, jitter, or pin-level timing values, use the manufacturer datasheet as the release source of truth.

یادداشت‌های طراحی
Treat the AD9500BP as a high-speed timing device rather than a generic digital IC. Route the reference clock, differential inputs, complementary ECL outputs, trigger, reset, and 8-bit delay-control signals with short paths and controlled return paths. Confirm the package-specific pinout and exposed connection requirements from the current Analog Devices package drawing before committing the PCB land pattern.
Use the manufacturer's ECL input and output termination recommendations and keep the timing reference distribution symmetrical. Differential inputs can improve noise immunity, but incorrect common-mode voltage, termination, or trace geometry can negate that benefit. Validate edge rate and timing behavior at the intended clock frequency with the final external driver, loads, and board construction.
Do not assume that 10 ps code resolution equals 10 ps absolute accuracy. Real delay accuracy also depends on the reference clock, calibration, temperature, supply behavior, output loading, and the selected code. Build a code-versus-delay calibration table for the complete instrument and retain margin against the timing requirements of the ATE or pulse-generation system.
Separate the timing-control path from noisy switching or high-current return paths. Keep the delay-control bus away from sensitive analog or clock-reference traces where practical, and use a solid ground-plane strategy. Because the verified data does not provide exact pin names or recommended layout values, use the current manufacturer datasheet and application guidance as the controlling reference.
