TMS320C54V90BGGU

Digital Signal Processor Dsp Overview

The TMS320C54V90BGGU is a Texas Instruments digital signal processor designed for full-featured, high-performance modem technology. It integrates proprietary firmware to perform modem signal processing, V.42/V.42bis compression, and AT command interpretation. The device features 40K x 16-bit dual-access on-chip RAM and 128K x 16-bit on-chip ROM. It supports data rates from 300 bps to 56 Kbps with standards including V.90, V.34, and various fax modulations. Instruction execution time is 8.5 ns (117.96 MIPS) or 17 ns (58.98 MIPS) for the 3.3-V power supply configuration.

Digital Signal Processor Dsp Feature Summary

• Portable devices such as PDAs and digital cameras

Digital Signal Processor Dsp Procurement Notes

Verify that the component matches the specific BGA package suffix GGU. Confirm the operating temperature range aligns with system requirements, noting revisions have adjusted the recommended operating conditions. Ensure compatibility with the Si3016 line-side DAA for complete modem functionality.

Digital Signal Processor Dsp Selection Notes

Select this model when a transformerless integrated DAA solution is required to reduce cost and area. Choose the BGA package (GGU suffix) for footprint compatibility with the TMS320VC5402. Consider the 17-ns instruction execution time if utilizing the 3.3-V power supply configuration.

Digital Signal Processor Dsp Part Context

This part number designates the BGA-packaged version of the TMS320C54V90 DSP. The alternative QFP package is designated by the BPGE suffix. The device functions as one half of a two-chip modem solution, paired with the Si3016 DAA.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C54V90BGGU is footprint compatible with the TMS320VC5402.
