AD9500WAFER 概要
A digitally programmable delay generator (DPG) is a category of timing IC that takes a trigger event (rising edge of an input pulse) and produces a single output pulse delayed by a precisely controlled interval that is set digitally through a parallel or serial interface. In the broader component taxonomy, the AD9500 sits under timing ICs -> clock & timing -> clock generators, with strong affinity to phase-locked loops (PLLs), time-to-digital converters (TDCs), and voltage-controlled delay lines (VCDLs). It functions as a "time-to-pulse" converter in pulse-position modulation, time-of-flight measurement, and radar ranging applications.
Key features of the AD9500 include 8-bit delay programming resolution, an analog fine-adjust input for analog sweep or vernier trimming, a stable trigger-to-output delay versus supply and temperature, and CMOS/TTL-compatible trigger and output levels. The device operates from a single +5 V supply and provides low-jitter, low-temperature-coefficient timing suitable for high-resolution pulse generation. The wafer form factor makes it attractive for OEM integrators building custom timing modules, multi-chip modules (MCMs), or systems-on-chip hybrid stacks where space is critical.
In a typical radar or lidar ranging system, the AD9500WAFER serves as the precision time-reference element that produces the transmit pulse and a precisely delayed reference for the receive path. Its 8-bit programmable delay, combined with analog fine-adjust, gives a total of approximately 10 bits of effective time resolution in many configurations. In automated test equipment (ATE), the AD9500 generates clock delays used for timing-margin testing of high-speed digital ICs, with the analog fine-adjust providing the sub-LSB timing vernier needed to characterize edge placement accuracy.
When using the AD9500WAFER in a die form factor, designers must consider die-handling, ESD protection, wire-bond or flip-chip attach, plus substrate/die-attach thermal management, as these are not handled by a standard package. Bare die also typically lacks the burn-in and temperature-screening benefit of packaged grades, so reliability must be evaluated in the integrator's MCM process.

Pulsed Radar Range Timing
The AD9500WAFER serves as a digitally programmable delay generator that produces precisely delayed trigger pulses between the radar transmitter and the receiver gate in pulsed radar systems. Its 8-bit digital delay programming plus analog fine-adjust input yields roughly 10 bits of effective timing resolution, which is critical for sub-meter range-bin discrimination in short-range surveillance and perimeter radar. The bare-die form factor integrates directly into radar front-end MCMs, eliminating the parasitic inductance of an external packaged delay line and enabling tighter timing alignment between transmit/receive paths.
おすすめ
Lidar Time-of-Flight Generation
In lidar ranging modules, the AD9500WAFER generates the precisely timed transmit pulse and the matched delay reference for the return-pulse sampling window, directly determining the achievable distance resolution. With its CMOS/TTL-compatible trigger and output levels, it interfaces cleanly to FPGA-based timing controllers and pulsed laser drivers. The 8-bit digital delay programming enables coarse delay selection over the full ranging interval, while the analog fine-adjust input trims the sub-nanosecond timing offset that establishes the system's minimum resolvable distance bin.
おすすめ
Automated Test Equipment (ATE) Timing Margins
The AD9500WAFER provides ATE pin-electronics timing paths with digitally programmable edge placement and analog vernier trim, allowing characterization of timing-margin behavior in high-speed digital ICs. The 8-bit digital delay sets the coarse edge step, while the analog fine-adjust delivers sub-LSB edge-placement resolution needed to validate setup/hold margins on sub-nanosecond interfaces. Bare-die integration permits placing the delay generator adjacent to the DUT socket driver, minimizing trace-induced timing skew and improving measurement repeatability compared to a packaged part on a remote timing board.
おすすめ
Sonar Beamforming Delay Network
In active sonar arrays, the AD9500WAFER functions as a per-channel programmable delay element that time-aligns transmit or receive pulses across hydrophone elements, enabling beam-steering and synthetic-aperture imaging. Its 8-bit digital programming plus analog fine-adjust gives system designers roughly 10 bits of effective delay resolution per channel, sufficient for narrow-beam steering at typical sonar wavelengths. The bare-die form factor allows integration directly onto the sonar-array substrate, reducing inter-channel timing skew caused by long PCB traces between packaged delay lines and transducer elements.
おすすめ
High-Resolution Pulse Generation
The AD9500WAFER generates single, precisely timed pulses with 8-bit digital delay programming and analog fine-adjust, supporting pulse-position modulation (PPM) communication, laser ranging, and time-domain reflectometry. The CMOS/TTL output level drives downstream laser-diode drivers, fast comparators, or FPGA event-capture inputs directly without additional level translation. Bare-die integration allows the delay generator and the downstream pulse-driver circuit to be co-located on the same MCM substrate, which is critical when the pulse width is comparable to the propagation delay of a conventional PCB trace.
おすすめ
Medical Imaging Timing
The AD9500WAFER supplies precisely timed trigger pulses for ultrasound transducer excitation, gamma-camera coincidence timing, and PET time-of-flight front-ends where deterministic, sub-nanosecond pulse placement is required. Its 8-bit digital delay programming combined with analog fine-adjust provides the timing resolution needed to align transmit bursts and receive-window gates across transducer array elements. The bare-die form factor supports integration into compact probe-head modules or bedside imaging cartridges, reducing the interconnect delay that would otherwise be introduced by an external packaged delay generator.

設計ノート
The AD9500WAFER is supplied as IC Die, not a packaged part. Bare die requires controlled ESD handling (typically HBM Class 1C or better per the wafer-pack specification) and a die-attach/wire-bond process qualified for hybrid/MCM production. Do not attempt to substitute a packaged AD9500 onto a die-attach substrate without redesign; the package adds parasitic inductance that defeats the purpose of bare-die integration in high-resolution timing paths.
When integrating the AD9500WAFER into an MCM, place the trigger input and output traces with controlled-impedance (typically 50 ohm microstrip or stripline) and matched electrical lengths to preserve timing fidelity. Keep analog fine-adjust traces short and isolated from digital programming lines to minimize crosstalk into the timing-critical edges. Provide local decoupling (typically 100 nF ceramic plus 10 uF tantalum) within 2 mm of the supply bond pad to suppress switching-induced jitter.
The CMOS/TTL-compatible trigger and output levels are fast edges capable of generating radiated EMI in the MCM substrate. Maintain solid ground-return stitching vias along the trigger and output paths, and consider a guard trace tied to ground around the analog fine-adjust input to reject substrate-noise pickup. Trigger-to-output jitter performance depends strongly on supply-rail cleanliness; use a low-noise LDO (e.g., a TPS7A30-series or an ADP151-class part) rather than a switching regulator directly upstream of the AD9500WAFER supply bond.
コンプライアンス情報
RoHS, REACH, lead-free, and halogen-free status for the AD9500WAFER bare-die product was not present in the verified web data and is marked 'unknown'. AEC-Q100 is not applicable because this is a timing IC, not an automotive-grade part. Military/aerospace applications should use the MIL-STD-883 screened AD9500/883B packaged sibling. Conflict-minerals status assumed compliant per standard Analog Devices policy; confirm via the manufacturer product page for production procurement.
