Digital Signal Processor Dsp Procurement Notes

Verify the specific package suffix against the datasheet part numbers. The PGE suffix corresponds to the 144-pin LQFP package, while GGU denotes the 144-pin BGA. Confirm that the required revision matches the production data status listed in the document history.

Digital Signal Processor Dsp Selection Notes

Select the PGE suffix for plastic low-profile quad flatpack mounting or the GGU suffix for ball grid array configurations. Ensure the host system supports either the serial RS-232 interface via the integrated UART or the 8-bit parallel host port interface (HPI8). Verify power supply requirements for the 1.5-V core and 3.3-V I/O pins.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C54x DSP family. It is specifically engineered as a two-chip modem solution when paired with the Si3016 line-side DAA. The device utilizes standard C54x architecture enhanced with dedicated modem algorithms and non-volatile EEPROM configuration storage.

Digital Signal Processor Dsp FAQ

What are the supported modulation standards?

The device supports V.90, V.34, V.32bis, V.32, V.22bis, V.22, V.23, V.21, Minitel, Bell 212, and Bell 103.

How is the Host Port Interface configured?

The HPI can be enabled by driving the HPIENA pin high during reset. It supports both multiplexed and non-multiplexed modes via the HPI16 pin.

What is the function of the MP/MC pin?

The MP/MC pin selects between microprocessor mode (high) and microcomputer mode (low) at reset, determining whether the internal ROM is mapped into program space.
