IDT82P2808BBG

Telecom Overview

The IDT82P2808BBG is an 8(+1) channel high-density T1/E1/J1 Line Interface Unit manufactured by Renesas Electronics Corporation. It integrates eight independent channels plus one monitoring channel for short-haul applications, supporting 100 Ω T1, 120 Ω E1, 110 Ω J1 twisted pair cables, and 75 Ω E1 coaxial cable configurations. The device operates within a supply voltage range of 3V to 3.6V and supports data rates up to 2.048Mbps. It features per-channel programmable receive and transmit termination options, jitter attenuators, and comprehensive diagnostic facilities including BPV/CV detection and error counters. The component is housed in a 416-pin PBGA package.

Telecom Feature Summary

• Integrates 8+1 channels with configurable line interface options for differential and single-ended modes
• Supports fully integrated software-selectable receive and transmit impedance matching
• Includes dual jitter attenuators (RJA & TJA) for each receiver and transmitter channel
• Provides user-programmable arbitrary waveform templates alongside preset waveform options

Telecom Applications

• Short haul T1, E1, and J1 line interface unit deployments
• Telecommunications network infrastructure requiring high-density channel integration
• System testing utilizing built-in PRBS, QRSS, and ARB pattern generation and detection

Telecom Procurement Notes

Verify the specific ordering suffix BBG against official manufacturer documentation to confirm the exact package type and moisture sensitivity level. Ensure that any requested substitutions maintain compatibility with the required 416-pin PBGA form factor and electrical specifications defined in the datasheet.

Telecom Selection Notes

Select this component when designing systems requiring multiple T1/E1/J1 interfaces within a compact footprint. Evaluate the available microprocessor interface options, such as serial or parallel Intel/Motorola configurations, to ensure seamless integration with the host controller architecture.

Telecom Part Context

This part belongs to the IDT82P2808 family of high-density line interface units. It serves as a specialized solution for telecommunications equipment manufacturers needing to consolidate multiple physical layer interfaces into a single integrated circuit, reducing overall system board area and bill of materials complexity.

Telecom Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify that any alternative components support the same 8(+1) channel configuration and 416-pin PBGA package dimensions.
