DSP56311VF150B1

Digital Signal Processor Dsp Overview

The NXP DSP56311VF150B1 is a 24-bit digital signal processor from the DSP56300 family, operating at a maximum clock frequency of 150 MHz. It features a high-performance core capable of up to 150 MMACS, with performance doubling to 300 MMACS when utilizing the integrated Enhanced Filter Coprocessor (EFCOP). The device employs a single-clock-cycle-per-instruction engine compatible with DSP56000 code and includes a 56-bit barrel shifter. Power management utilizes a 1.8 V core voltage with independent 3.3 V I/O supplies. Internal memory configuration supports up to 128 K × 24 bits of RAM, distributed across program, X data, and Y data spaces.

Digital Signal Processor Dsp Feature Summary

• Enhanced Filter Coprocessor (EFCOP) executes filter algorithms in parallel with the core, supporting FIR and IIR modes for echo cancellation and correlation.
• DSP56300 Core with fully pipelined 24 × 24-bit MAC, 56-bit barrel shifter, and hardware stack support.
• Integrated peripherals include two Enhanced Synchronous Serial Interfaces (ESSI), an 8-bit Host Interface (HI08), SCI, and Triple Timer.
• Six-channel Direct Memory Access (DMA) controller supporting internal/external transfers and circular buffering.

Digital Signal Processor Dsp Applications

• Wireless and wireline infrastructure applications
• Multi-channel wireless local loop systems
• High-speed modem banks
• IP telephony

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and lead-free status. Ensure that the 1.8 V core and 3.3 V I/O power requirements are met by the system design. Confirm availability through authorized distributors as this component may be subject to end-of-life or lifecycle changes.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-throughput filtering operations without impacting channel throughput. Consider the EFCOP capabilities if the design involves echo cancellation or general-purpose convolution. Ensure the external memory interface meets the timing requirements for 150 MHz operation, particularly regarding DRAM access limits above 100 MHz.

Digital Signal Processor Dsp Part Context

The DSP56311 is part of the Freescale (now NXP) DSP56300 family, designed for network applications. It shares architectural similarities with other members like the DSP56311VL150B1 but differs in specific packaging and suffix configurations. The device integrates significant on-chip memory to reduce external dependency, making it suitable for complex signal processing tasks.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the DSP56300 family should be evaluated based on pin compatibility and memory configuration. Verify that alternative parts support the same 24-bit architecture and peripheral set. Cross-reference with NXP documentation for updated equivalents if the current part is discontinued.
