LC75055PE-6158-H

Digital Signal Processor Dsp Overview

The LC75055PE-6158-H is a digital sound processor designed for car audio applications. It integrates an audio signal processor, analog-to-digital converter (A/D), digital-to-analog converter (D/A), and volume control into a single chip. Programs are downloaded from internal Flash ROM into DSP RAM; on-board programming to the Flash ROM is not available, with data programmable only before delivery by the manufacturer. The device operates with a logic supply voltage of 1.5V, while the PLL circuit, crystal oscillation, digital I/O power supply, and CODEC analog power supply all require 3.3V.

Digital Signal Processor Dsp Feature Summary

• Integrated Car Audio DSP combining signal processing, A/D, D/A, and volume control
• Internal Flash ROM for program storage with pre-delivery programming only
• Dual voltage operation: 1.5V for logic and 3.3V for peripherals and analog sections

Digital Signal Processor Dsp Applications

• Car audio digital signal processing systems
