IDT821024PP

Codecs Overview

The IDT821024PP is a single-chip, four-channel PCM CODEC featuring on-chip filters. It provides analog-to-digital and digital-to-analog conversions while supporting both A-law and μ-law companding. The device incorporates digital filters that perform necessary transmit and receive filtering for voice telephone circuits to interface with time-division multiplexed systems. These digital filters operate using an internal clock derived from MCLK. Fixed filters within the component set the transmit and receive gain and frequency response characteristics.

Codecs Feature Summary

• Integrates four-channel PCM CODEC functionality with on-chip analog-to-digital and digital-to-analog conversion capabilities.
• Supports standard A-law and μ-law companding formats for voice signal processing.
• Includes built-in digital filters for transmit and receive paths to interface with time-division multiplexed systems.
• Utilizes fixed filters to establish specific transmit and receive gain and frequency response parameters.

Codecs Applications

• Voice telephone circuit interfaces
• Time-division multiplexed system connections

Codecs Procurement Notes

Verify the exact package type and lead configuration against official Renesas or IDT documentation before procurement. Confirm that the PP suffix corresponds to the required plastic package variant and pin arrangement. Ensure compatibility with existing board layouts regarding pitch and dimensions. Check for any specific handling requirements associated with the component's moisture sensitivity level. Validate that the operating temperature range meets the design specifications.

Codecs Selection Notes

Select this component when a multi-channel PCM codec with integrated filtering is required for TDM applications. Consider the support for both A-law and μ-law standards if regional interoperability is needed. Evaluate the internal clock derivation from MCLK to ensure synchronization with the host system. Verify that the fixed filter characteristics align with the desired voice channel frequency response and gain requirements.

Codecs Part Context

This component belongs to the family of single-chip PCM CODECs designed for telecommunications. It integrates multiple functions typically requiring separate discrete components into one package. The device simplifies the design of voice channels in digital telephony equipment by providing essential conversion and filtering capabilities on a single chip.

Codecs Replacement Considerations

Consult official manufacturer substitution guides for verified alternatives. Ensure any replacement maintains the same four-channel architecture and package footprint. Verify compatibility with existing A-law and μ-law companding support. Confirm that the substitute device offers equivalent digital filter performance for TDM interfacing.
