ADSP-2105BP-55REEL

Digital Signal Processor Dsp Overview

The ADSP-2105BP-55REEL is a fixed-point digital signal processor from the Analog Devices ADSP-21xx series. It operates at a maximum clock rate of 20 MHz and features an integrated 3 kB on-chip RAM. The device utilizes a synchronous serial port for data communication and is designed for surface-mount installation. It functions within a commercial temperature range of -40°C to +85°C and requires a 5.00 V supply voltage for both I/O and core operations.

Digital Signal Processor Dsp Feature Summary

• Fixed-point DSP architecture with 20 MHz clock speed
• Integrated 3 kB data RAM
• Synchronous Serial Port (SSP) interface
• 68-pin PLCC package

Digital Signal Processor Dsp Applications

• Wavefront array processors
• STD-Bus system implementations

Digital Signal Processor Dsp Procurement Notes

Verify component status as the base ADSP-2105 model is listed as obsolete in public records. Confirm that the REEL suffix indicates tape-and-reel packaging rather than functional changes. Ensure compatibility with existing 5V power domains and 68-pin footprints during sourcing.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring fixed-point processing at 20 MHz with minimal external memory dependencies due to the 3 kB internal RAM. Verify that the 68-PLCC package fits the target PCB layout and that the operating temperature range meets environmental requirements.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-21xx family, which includes variants like the ADSP-2105BP-80. While specific datasheets for the -55REEL suffix are not publicly detailed, it shares architectural similarities with other members of the series, such as the ADSP-2105BP-80, differing primarily in speed grade and packaging format.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-2105BP-80 is a documented variant within the same family. Verify pinout and electrical specifications before substitution. No direct public substitute part numbers are confirmed for this specific reel-packaged variant.
