821024JG

Overview

The Renesas Electronics Corporation 821024JG is a single-chip, four-channel PCM CODEC featuring on-chip digital filters. It provides analog-to-digital and digital-to-analog conversions for voice telephone circuits interfacing with time-division multiplexed systems. The device supports both A-law and μ-law companding standards. Digital filtering is executed by internal digital signal processors operating from an MCLK-derived clock. The unit operates within a supply voltage range of 4.75V to 5.25V and functions across a temperature range of -40°C to +85°C. It utilizes a 32-pin PLCC package.

Feature Summary

Integrates four independent channels for simultaneous audio processing
Includes fixed transmit and receive filters for gain and frequency response control
Supports standard telephony companding algorithms

Applications

Time-division multiplexed communication systems
Voice telephone circuit interfaces
PCM audio transmission equipment

Procurement Notes

Verify the specific suffix JG against official documentation to confirm the 32-PLCC package configuration. Check current status as Last Time Buy or End-of-Life notifications may apply. Confirm moisture sensitivity level and RoHS compliance requirements prior to ordering. Ensure compatibility with existing PCB footprints for the specified lead type.

Selection Notes

Select this component when designing systems requiring integrated PCM codec functionality with built-in DSP filtering. Verify that the 32-PLCC package fits the mechanical constraints of the target assembly. Ensure the system clock architecture can derive the necessary internal clock from MCLK for proper filter operation.

Part Context

This part belongs to the 821024 family of quad-channel PCM codecs. Variants such as the 821024PPG offer similar functionality in different packages like TQFP. The core architecture remains consistent across the series, focusing on voice-grade audio conversion with integrated signal processing capabilities for telecommunications applications.
