Overview
The 821024PPG is a single-chip, four-channel PCM CODEC manufactured by Renesas Electronics. It integrates analog-to-digital and digital-to-analog conversion capabilities with on-chip filters for voice telephone circuits. The device supports both A-law and μ-law companding standards. It operates within a supply voltage range of 4.75 V to 5.25 V and functions across an operating temperature range of -40°C to +85°C. The component utilizes a TQFP-44 surface-mount package. It features four ADCs and four DACs with an 8-bit resolution and an 8 kHz conversion rate. The interface type is PCM.
Feature Summary
- Integrates four independent audio channels with dedicated analog-to-digital and digital-to-analog converters.
- Includes internal digital signal processors that perform transmit and receive filtering derived from the master clock.
- Supports standard telephony companding algorithms including A-law and μ-law for voice signal processing.
Applications
- Time-division multiplexed systems
- Voice telephone circuit interfaces
- Multi-channel audio codec implementations
Procurement Notes
This component is designated as Last Time Buy or End-of-Life status. Verify current availability through authorized distributors immediately. Confirm RoHS compliance details and moisture sensitivity level before finalizing procurement plans due to potential supply chain constraints associated with discontinued products.
Selection Notes
Select this part only if legacy compatibility with existing 821024 designs is required. Ensure system requirements match the fixed 8-bit resolution and 8 kHz sampling rate. Verify that the TQFP-44 package dimensions fit the target PCB layout. Consider migration paths to newer Renesas audio solutions if new design flexibility is needed.
Part Context
The 821024PPG belongs to the 821024 family of quad PCM codecs. It shares core functionality with variants like the 821024JG but differs in packaging. The PPG suffix indicates a lead-free, halogen-free TQFP-44 package. This series was designed for telecommunications applications requiring multi-channel voice digitization.
Replacement Considerations
No direct active substitutes are listed in official documentation. Evaluate migration to newer Renesas audio codec families for new designs. Verify pinout compatibility if considering alternative vendors for legacy maintenance.
