ADSP-2103KP-40 - 24-Bit 10.24 MHz DSP | Analog Devices
料号： ADSP-2103KP-40 ✗ 停产ADSP-2103KP-40 概述
A digital signal processor, or DSP, is a specialized microprocessor architecture optimized for filtering, Fourier analysis, waveform generation, error correction, and other mathematically intensive operations. Within the semiconductor hierarchy, a DSP belongs to the integrated-circuit and embedded-processor categories. Unlike a general-purpose control processor, it executes repetitive numerical sequences efficiently and provides deterministic performance for real-time signal chains.
The ADSP-2103KP-40 combines a 24-bit processor word length with a 10.24 MHz clock. Its 24-bit architecture supports high-resolution fixed-point signal calculations, while the ADSP-2100 platform provides dedicated hardware and memory structures suited to digital filtering and other DSP workloads. The -40 suffix identifies the speed grade, and the PQCC68 plastic package supports conventional through-hole PCB assembly rather than a fine-pitch surface-mount footprint.
This device belongs to the ADSP-2100 family of DSP microcomputers, whose architecture includes data memory, program memory, timers, serial ports, and a host interface. The ADSP-2103KP-40 is positioned for systems requiring dedicated real-time signal processing without the complexity of a general-purpose embedded processor. Its dual serial-port and host-interface resources can support converters, communication links, host controllers, and data-transfer peripherals.
Typical applications include digital audio processing, communications filtering, speech processing, industrial control, instrumentation, and embedded measurement systems. In each case, the processor can execute time-critical signal algorithms while coordinating data movement through its dedicated serial and host interfaces. Designs should also account for the relatively high clock rate and the electrical and timing requirements of a 24-bit DSP architecture.
PCB implementation requires the correct 68-pin PQCC68 footprint, adequate bypass-capacitor placement, and careful routing of processor, memory, serial-port, clock, and control signals. Because this is a through-hole plastic leaded chip carrier, connector or socket compatibility and mechanical clearances should be checked before layout release. Use the manufacturer's pin-description table and electrical characteristics for final signal integrity and power-distribution decisions.
This product record combines processor identity, package information, verified source links, engineering application guidance, and purchasing resources for the ADSP-2103KP-40. It is intended to help engineers distinguish this exact 24-bit, 10.24 MHz ADSP-2100 member from other speed grades, package variants, and modern processors with different architectures or toolchains.

典型应用
ADSP-2103KP-40 适用于 6 应用s: Digital Audio Signal Processing, Communications Filtering, Industrial Control and Condition Monitoring, Speech and Measurement Processing, Legacy Embedded DSP Platform, Real-Time Control Signal Conditioning.
Digital Audio Signal Processing
The ADSP-2103KP-40 fits legacy digital audio systems that require deterministic fixed-point signal calculations at a 10.24 MHz clock rate. Its 24-bit word length is appropriate for filtering, mixing, equalization, and waveform-generation algorithms when the complete signal path can be implemented within the ADSP-2100 architecture. The device can operate as the main real-time processor, receiving serial audio data and transferring control or status information through its host interface. Because the part uses a 68-pin PQCC68 package, designers can preserve through-hole board construction while avoiding the mechanical and software changes associated with a modern surface-mount DSP. Confirm audio converter interfaces, supported clocking, memory requirements, and the legacy development toolchain before beginning a new design.
推荐
Communications Filtering
The ADSP-2103KP-40 can serve as the fixed-point signal-processing engine in communications equipment requiring real-time filtering and related numerical operations. Its 24-bit processor architecture and 10.24 MHz clock provide a defined computational platform for FIR, IIR, modulation-support, and signal-conditioning tasks when sized against the system's required sample rate and filter order. The ADSP-2100 family's serial ports can connect to converters or communication peripherals, while the host interface provides a path for control traffic. For a new implementation, calculate throughput from the actual algorithm and sampling requirements rather than relying only on clock frequency. Validate electrical timing, memory interface behavior, and software toolchain compatibility before using this processor in a communications design.
推荐
Industrial Control and Condition Monitoring
The ADSP-2103KP-40 is appropriate for legacy industrial control systems in which a DSP algorithm must monitor or transform sensor signals in real time. The processor can execute fixed-point filtering, control calculations, and data-conditioning routines while using the ADSP-2100 family's timers and serial interfaces for peripheral coordination. Its 10.24 MHz clock makes system timing and workload budgeting essential: the design must verify that filter complexity, control-loop latency, and serial data movement remain within available processor cycles. The through-hole PQCC68 package can simplify integration into existing industrial controller boards, but production use requires attention to operating-temperature limits, supply regulation, grounding, and long-term component availability. Functional safety claims should be based only on a complete system assessment and any applicable qualification documentation.
推荐
Speech and Measurement Processing
The ADSP-2103KP-40 can support embedded speech-processing or measurement front ends that require repeatable numerical operations on sampled signals. Its 24-bit fixed-point architecture is suited to filtering, feature extraction, spectral processing, and parameter estimation when the software is adapted to the ADSP-2100 execution model. At 10.24 MHz, designers should benchmark the full algorithm, including data movement and scaling, because convolution and transform workloads can consume processor cycles rapidly. Serial ports can interface with converters or host-side control logic, while program and data memory requirements determine whether external memory is needed. The 68-pin plastic LCC package preserves compatibility with through-hole legacy instrument architecture. Confirm converter timing, input bandwidth, memory capacity, and toolchain support before committing the processor to a production instrument.
推荐
Legacy Embedded DSP Platform
The ADSP-2103KP-40 is especially relevant to maintenance and replication of legacy embedded systems based on the ADSP-2100 family. Its known identity as a 24-bit, 10.24 MHz processor in a 68-pin PQCC68 package allows engineers to match an existing board without changing the mechanical footprint. A replacement or migration project should compare the original board schematic against the manufacturer pin-description table, then verify processor features such as serial ports, timers, memory organization, host interface, and reset behavior. Software may also require the corresponding legacy assembler, linker, simulator, and runtime libraries. The through-hole package supports socketed or direct-board construction, making it useful for industrial replacement and long-lived equipment support. Record exact ordering details and date-code requirements when planning a supply chain for the assembly.
推荐
Real-Time Control Signal Conditioning
The ADSP-2103KP-40 can be used in real-time signal-conditioning subsystems that prepare analog measurements for a supervisory controller. Typical tasks include digital filtering, scaling, rate conversion, and extraction of control variables at a deterministic 10.24 MHz processing rate. The dedicated DSP architecture separates mathematically intensive conditioning work from a host or microcontroller, reducing the burden on a general-purpose control processor. The ADSP-2100 serial and host interfaces allow data to pass between converters, the signal processor, and supervisory logic. Designers must budget algorithm execution time, account for serial-port bandwidth, and preserve headroom for interrupt handling and background tasks. Because operating voltage, temperature range, and detailed timing limits are not listed in the product record, those values must be obtained from the manufacturer datasheet before schematic approval.

设计说明
Use the manufacturer's PQCC68 package drawing to create the PCB footprint and verify every signal name against the ADSP-2100 Family DSP Microcomputers pin-description table. Confirm lead pitch, pin numbering, body clearance, and any socket dimensions before routing. Keep clock, reset, and memory-interface traces short, and place bypass capacitors close to their associated supply pins. Because this is a through-hole leaded package rather than a surface-mount LCC, also check drilling tolerances, annular rings, and mechanical clearance around the plastic body.
Plan the processor clock and serial interfaces from the manufacturer's electrical characteristics rather than treating the 10.24 MHz operating frequency as sufficient timing guidance by itself. Route the clock away from high-current switching nodes, provide a stable reference path, and follow recommended return paths through the plane. Account for signal propagation, setup, hold, and external-device timing at the processor pins. Use the datasheet timing tables to establish which signals require controlled impedance or series termination.
Do not finalize the power tree until the manufacturer confirms the required supply voltage, tolerance, sequencing, and operating limits for the exact ADSP-2103KP-40. Decouple each supply domain at the package pins, keep high-current return paths out of sensitive signal areas, and confirm ground continuity around the processor. Verify startup, reset, and input states so that the DSP remains in a defined condition during power transitions. These checks are especially important when updating an older board with modern regulators that have different quiescent or sequencing behavior.
Avoid treating another ADSP-2100-family processor as an automatic substitute because family membership does not guarantee identical memory, peripheral, clock, voltage, or pin configuration. Likewise, matching a 68-pin package count does not prove pin compatibility. Confirm the full ordering code, speed grade, pin table, electrical limits, and software model. For existing products, preserve traceability by recording the manufacturer, exact suffix, date code, and approved source requirements in the assembly documentation.
