IDT82V1054APFG8

Telecom Overview

The IDT82V1054APFG8 is a quad-channel PCM CODEC with on-chip digital filters, manufactured by Renesas Electronics Corporation. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 64-pin TQFP package measuring 14x14 mm. The device supports a single +3.3 V power supply with a typical current consumption of 50 mA. It features software-selectable A/µ-law and linear code conversion, meeting ITU-T G.711-G.714 standards. The integrated DSP enables programmable AC impedance matching, transhybrid balance, frequency response correction, and gain setting. It interfaces via MPI and supports two PCM buses with data rates from 512 kbits/s to 8.192 Mbits/s.

Telecom Feature Summary

• Integrated Digital Signal Processor (DSP) for real-time voice signal conditioning including impedance matching and hybrid balance.
• Dual PCM bus architecture supporting flexible time slot assignment and up to 128 programmable slots.
• Hardware Ring Trip mechanism for immediate ringing signal cessation upon off-hook detection.
• On-chip tone generators and chopper clocks for SLIC control and system testing.

Telecom Applications

• Central Office Switches
• Private Branch Exchange (PBX) systems
• Digital Loop Carriers (DLC)
• Integrated Access Devices (IADs)

Telecom Procurement Notes

Verify the manufacturer marking matches Renesas Electronics Corporation or Integrated Device Technology, Inc., as IDT was acquired. Confirm the suffix 'PFG8' corresponds to the 64-TQFP package and lead-free RoHS compliance. Ensure the operating voltage aligns with the specified +3.3 V requirement and check for any specific industrial grade temperature certifications if required for the deployment environment.

Telecom Selection Notes

Select this component when a quad-channel solution with programmable analog front-end filtering is required. It is suitable for applications needing direct SLIC signaling integration without external DSPs. Consider the 64-pin TQFP footprint for PCB layout constraints. Verify that the system clock requirements match the supported master clock frequencies ranging from 1.536 MHz to 8.192 MHz.

Telecom Part Context

This part belongs to the IDT82V1054A family of programmable PCM CODECs. It is designed for telecommunications interface applications requiring high integration of analog and digital functions. The device replaces discrete solutions combining CODECs, DSPs, and hybrid transformers, thereby reducing board space and power consumption in digital telephony equipment.
