ADSP-2103BP-40 - 24-Bit 10.24 MHz DSP | Analog Devices
部品番号: ADSP-2103BP-40 ✓ 生産中ADSP-2103BP-40 概要
A digital signal processor is a microprocessor architecture optimized for filtering, waveform generation, spectral analysis, and other operations involving repeated multiply-accumulate calculations. DSP processors sit between general-purpose microprocessors and dedicated function-specific controllers: they retain programmable software control while accelerating arithmetic-heavy signal chains. The ADSP-2103 applies this architecture to compact embedded processing tasks where deterministic numerical computation and compact integration are important.
The ADSP-2103BP-40 uses a 24-bit architecture and a 10.24 MHz clock, while its 3 kB RAM provides on-chip working storage for program and data. The fixed-point format supports integer-based digital signal processing and avoids requiring a separate floating-point unit. Its 68-pin PLCC package supports surface-mount assembly and provides a defined lead arrangement for compact control and processing boards.
The ADSP-2100 family shares a common core containing computation units, data address generators, and a program sequencer. Family members differentiate themselves through memory capacity, serial-port resources, timers, and other integrated functions. Because software support and external hardware requirements depend on the selected family member and complete application architecture, designers should consult the ADSP-2100 family documentation before finalizing memory, clock, and peripheral assignments.
Typical uses include industrial motor and process control, communications filtering, audio and speech processing, instrumentation, vibration analysis, and embedded measurement systems. In these systems, the processor can implement finite impulse response and infinite impulse response filters, signal transforms, control loops, and data-acquisition algorithms while coordinating inputs from converters and sensors.
PCB design should preserve the package pin arrangement and provide clean power, ground, clock, and signal routing. Decoupling capacitors should be placed close to the supply pins, while clock and high-speed signal paths should avoid noisy switching nodes. The designer should also confirm the required external memory interface, serial communications connections, and programming configuration from the manufacturer documentation.
This page combines the ADSP-2103BP-40 identity, package and timing information with application guidance, family alternatives, and design-focused selection criteria. These engineering references help teams evaluate the processor, plan board layouts, and identify where a software or architecture review is needed before production implementation.

主な用途
ADSP-2103BP-40 の用途: 6 件s: Industrial Motor and Process Control, Digital Audio and Speech Processing, Industrial Measurement and Signal Conditioning, Communications Filtering and Modulation, Vibration and Condition Monitoring, Programmable Instrumentation and Test Equipment.
Industrial Motor and Process Control
The ADSP-2103BP-40 fits compact industrial control loops that require deterministic fixed-point arithmetic, including filtering of sensed process variables and calculation of actuator commands. Its 24-bit architecture supports precise integer and fractional-point operations, while the 10.24 MHz clock provides a defined instruction-processing rate for loop timing. The 3 kB RAM can hold active coefficients and working variables when the algorithm fits the local memory budget. Place the processor on a 68-pin PLCC footprint and route its control outputs through appropriately isolated interface circuitry. Before finalizing the design, verify cycle timing, external memory requirements, supply limits, and operating-temperature requirements against the ADSP-2100 family documentation.
おすすめ
Digital Audio and Speech Processing
The ADSP-2103BP-40 is appropriate for programmable audio tasks such as filtering, mixing, equalization, and waveform generation. Its 24-bit fixed-point architecture supports high-resolution integer-based algorithms, and the 10.24 MHz clock establishes the processing rate for the selected sample rate and filter complexity. The 3 kB RAM can hold program variables and coefficients when the working set remains compact. A practical implementation would pair the processor with an audio converter and route the digital interface to the appropriate serial or memory resources. Confirm converter timing, supported data format, available program memory, and serial-port resources in the family documentation before freezing the audio signal chain.
おすすめ
Industrial Measurement and Signal Conditioning
The ADSP-2103BP-40 can implement digital filtering, calibration, and signal-conditioning functions in a compact measurement instrument. Its 24-bit fixed-point format is useful when coefficients and sample data are scaled into integer representation, while the 10.24 MHz clock supports time-based processing independent of a general-purpose host. The 3 kB RAM provides local working space for filters and control state, reducing the need for external memory in smaller designs. Connect the DSP to a suitable converter and sensor front end, then verify latency and bandwidth against the acquisition requirements. Power-supply design and PCB layout should isolate converter clocks from sensitive DSP inputs to preserve measurement integrity.
おすすめ
Communications Filtering and Modulation
The ADSP-2103BP-40 is suited to embedded communications functions that require programmable filters, waveform shaping, or spectral processing. Its 24-bit fixed-point architecture supports integer and fractional-point algorithms, and the 10.24 MHz clock provides a predictable processing basis for sampling and symbol-processing tasks. The 3 kB RAM can accommodate active filter coefficients and working buffers when the implementation is compact. In a communications design, connect the appropriate serial interface to a transceiver or codec and place clock and data routing away from switching power nodes. Validate throughput, memory depth, serial framing, and timing margins in the ADSP-2100 family documentation before implementing the modulation algorithm.
おすすめ
Vibration and Condition Monitoring
The ADSP-2103BP-40 can support embedded vibration monitoring by executing fixed-point filters, envelope calculations, and time-domain feature extraction close to the sensor interface. The 10.24 MHz clock gives a defined computational rate, while the 24-bit format allows careful scaling of sensor data and coefficients. The 3 kB RAM is suitable for active windows, state variables, and short processing buffers when the selected algorithm has a bounded working set. A practical system would use a suitable sensor and analog front end, followed by the DSP and a communications controller for reporting. Validate input bandwidth, execution time, dynamic range, and environmental requirements so the numeric resolution remains adequate throughout the monitored operating range.
おすすめ
Programmable Instrumentation and Test Equipment
The ADSP-2103BP-40 can act as the real-time processing core in programmable instrumentation, applying correction coefficients, digital filters, and waveform calculations to acquired samples. Its 24-bit fixed-point architecture supports deterministic numeric processing, and the 10.24 MHz clock provides a clear basis for estimating algorithm latency. The 3 kB RAM can support compact filter banks and working buffers when external program storage is used for larger code. Connect the DSP to a suitable converter, display or communications path, and input-conditioning circuitry. Because instrument accuracy depends on scaling, calibration, and clock quality, review the electrical characteristics and timing diagrams in the ADSP-2100 family datasheet before releasing the production design.

設計ノート
Plan the DSP supply network around the exact voltage and current limits listed in the ADSP-2100 family datasheet. Place the required bypass capacitors at the associated power pins and keep their ground returns short to the device. Separate analog-sensitive inputs and references from switching supplies where practical. Do not estimate junction temperature from the 10.24 MHz clock alone; calculate dissipation from the actual supply voltage, active current, I/O loading, and ambient conditions.
Preserve the 68-pin PLCC footprint and assign signals from the family pin-description table rather than from a generic package drawing. Keep clock routing short, use a continuous ground reference, and avoid routing high-current outputs beneath sensitive DSP inputs. Place external memory and serial-interface devices close enough to reduce board-trace delay and loading. Review every unused or reserved pin according to the manufacturer documentation before fabrication.
Changing to ADSP-2103BP-33 or ADSP-2103BP-50 can alter execution time even when the package remains compatible. Review timing-sensitive loops, serial framing, timers, and interrupt service routines after any clock-grade substitution. For ADSP-2101BP-40, also verify memory capacity, peripheral availability, and software dependencies because the ADSP-2101 and ADSP-2103 resource configurations differ. Record these checks as part of the hardware revision review.
Treat the DSP clock and serial data lines as high-speed signals despite the relatively modest 10.24 MHz processor clock. Use continuous reference planes, minimize stubs, avoid right-angle routing where control matters, and confirm that external memory and interface timing budgets include package and board delay. If analog conversion is part of the design, isolate converter clocks and switching nodes from the DSP input path to prevent correlated noise in measured samples.
