ADSP-21990BBC - 160 MHz 16-Bit Mixed-Signal DSP | Analog Devices
Артикул: ADSP-21990BBC ✓ АктивенADSP-21990BBC Обзор
A mixed-signal DSP is a semiconductor that integrates digital signal-processing logic with analog conversion functions. Its processing core executes filtering, control, and mathematical algorithms, while its integrated ADC converts incoming sensor, voltage, or current signals into digital data for real-time analysis. This integration reduces the need for separate converters and shortens the path between analog acquisition and digital control.
Key features include a 160 MHz DSP core with 16-bit data width, eight ADC channels, 14-bit conversion resolution, and a maximum sampling rate of 20 MSPS. Two sample-and-hold amplifiers support simultaneous sampling, which is important for three-phase motor drives and other systems where phase relationships must be preserved. The device is also identified as a 150 MHz-class DSP in distributor catalog data, while Analog Devices specifies the 160 MHz core in its official product description.
The ADSP-21990BBC combines a high-performance processor with dedicated mixed-signal resources rather than relying entirely on external converters. Its architecture supports deterministic real-time control loops and high-rate digital filtering. The 196-ball BGA package minimizes board area, although its fine pitch and thermal characteristics require careful PCB layout, power delivery, and reflow control.
Typical applications include industrial servo drives, motor-control inverters, power-conversion control, industrial automation, data acquisition, and real-time signal analysis. The integrated ADC is particularly useful when several analog channels must be sampled together, including current, voltage, position, and temperature feedback.
Design with the ADSP-21990BBC using the pin-description and power-supply tables in the manufacturer datasheet. Provide clean, decoupled supply rails, route high-speed signals with short return paths, and follow the package-specific land pattern and thermal layout guidance to preserve processor performance and converter accuracy.
This page combines core device characteristics, verified package information, application guidance, and same-family alternatives. It also distinguishes true board-level replacement options from parts that require firmware, instruction-set, or package redesign.

Типичное применение
ADSP-21990BBC подходит для 6 применениеs: Industrial Servo Motor Control, Three-Phase Power Inverter Control, Industrial Data Acquisition and Condition Monitoring, Power Conversion and Grid Control, Real-Time Signal Processing Node, Industrial Automation and Embedded Control.
Industrial Servo Motor Control
The ADSP-21990BBC fits industrial servo controllers that combine current-loop regulation with real-time signal conditioning. Its 160 MHz 16-bit core can execute the control law and filtering algorithms, while the integrated 8-channel 14-bit ADC samples feedback signals at up to 20 MSPS. Dual sample-and-hold amplifiers support simultaneous acquisition, helping preserve relationships among phase-current and voltage measurements. Placing the converter and processor in one 196-ball BGA package reduces analog interconnect length and keeps the control loop compact.
Рекомендуется
Three-Phase Power Inverter Control
The ADSP-21990BBC is suitable for three-phase inverter control where accurate current sensing and fast feedback determine loop stability. Its eight 14-bit ADC channels can acquire multiple voltage and current references at up to 20 MSPS, and the dual sample-and-hold amplifiers enable simultaneous sampling across selected inputs. The 160 MHz core provides the execution bandwidth for PWM synchronization, current regulation, and fault handling. Board design should keep sensor paths away from switching nodes and provide independent analog and digital return paths.
Рекомендуется
Industrial Data Acquisition and Condition Monitoring
The ADSP-21990BBC supports compact condition-monitoring systems that acquire vibration, strain, current, or process-control signals and perform analysis on-device. Eight 14-bit ADC channels at 20 MSPS provide the sampling capability needed for spectral analysis and waveform inspection, while the 160 MHz 16-bit core can implement digital filters and feature extraction without a separate processor. Simultaneous sampling is valuable when comparing phase or axis-dependent sensors. The BGA package reduces board area but requires fine-pitch assembly capability.
Рекомендуется
Power Conversion and Grid Control
The ADSP-21990BBC fits power-conversion controllers that need deterministic sampling, fast loop execution, and compact mixed-signal integration. The 8-channel 14-bit ADC at 20 MSPS can monitor input voltage, output voltage, inductor current, and phase current, while the 160 MHz DSP core executes control algorithms. Simultaneous acquisition supports accurate comparison of closely related measurements. Design the analog front end for the ADC input range, keep the switching power stage isolated from converter inputs, and follow the data sheet's thermal and decoupling guidance.
Рекомендуется
Real-Time Signal Processing Node
The ADSP-21990BBC can serve as a compact real-time processing node for filtering, modulation analysis, and embedded control in industrial equipment. Its 160 MHz 16-bit core provides deterministic arithmetic performance, and the integrated ADC removes the need for a separate high-speed converter when several channels are required. Eight inputs at 20 MSPS support waveform capture and real-time spectral processing within a single package. Applications should define clocking and trigger behavior carefully and reserve routing capacity for debug and communications interfaces.
Рекомендуется
Industrial Automation and Embedded Control
The ADSP-21990BBC suits industrial automation controllers that combine sensor acquisition with deterministic embedded signal processing. The 16-bit DSP core can execute motion-control or analysis algorithms, while the 8-channel ADC supports grouped analog feedback. Simultaneous sampling improves consistency when several measurements are mathematically related. For a new controller design, evaluate the mixed-signal partitioning carefully: use dedicated analog ground and supply connections, keep clock traces short, and confirm that the 196-ball BGA land pattern is compatible with the assembly and inspection process.

Заметки по проектированию
Treat the 196-ball BGA escape routing as the central PCB-layout constraint. Follow the manufacturer land pattern, keep analog, clock, and high-speed digital routes separated, and provide continuous ground references beneath the device. Fine-pitch escape vias should connect directly to the required BGA balls without long stubs, because excessive loop inductance can disturb clock quality and analog supply settling.
Use the power-supply and decoupling tables in the manufacturer datasheet to assign every supply ball and bypass capacitor. Place high-frequency ceramic capacitors immediately adjacent to the relevant device balls and connect their return path to the associated ground plane. Mixed-signal processors combine a switching digital core with a high-speed converter, so a shared, unpartitioned supply network can convert core current transients into analog sampling error.
Route the ADC inputs as short, controlled-impedance analog traces and keep them away from PWM outputs, clock nets, and high-current switching paths. Use the sample-and-hold capability only after verifying which channel groups are supported simultaneously in the device configuration. A solid analog ground region, minimal via count, and a return path beneath each sensitive input will generally produce more repeatable results than elaborate digital shielding alone.
Validate junction temperature and board heat spreading with the processor operating at its intended clock, conversion rate, and peripheral load. The 196-ball BGA exposes its primary thermal path through the package balls and PCB copper, so localized power dissipation should be distributed across the board rather than concentrated in a small area. Use the manufacturer thermal data and the actual board construction for final heat-sink and copper-pour decisions.
Do not select a suffix variant solely from the family name. Before ordering ADSP-21990BBC, ADSP-21990BST, or ADSP-21990BSTZ, compare the package drawings, ball maps, temperature grades, and ordering tables. Also verify the ADC input range and external front-end requirements; matching the core clock alone does not establish analog signal-chain compatibility.
