82P2288BCG

Overview

The Renesas Electronics Corporation 82P2288BCG is a high-density telecommunications interface integrated circuit designed for T1, E1, and J1 line applications. It functions as a transceiver supporting IEEE 1149.1 (JTAG) boundary scan protocols for system testing and configuration. The device operates within a supply voltage range of 3V to 3.6V and is rated for an industrial operating temperature range of -40°C to +85°C. It supports data rates up to 2.048Mbps and is housed in a 256-pin PBGA package with dimensions of 17x17mm. This component is suitable for demanding digital signal processing and network infrastructure environments requiring robust serial-to-parallel conversion capabilities.

Procurement Notes

Verify the specific suffix 'BCG' against official Renesas documentation to confirm pinout compatibility and package variant accuracy. Ensure that the 256-PBGA footprint matches the target PCB design constraints. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement specifications.

Selection Notes

Select this component when a high-channel-count transceiver with integrated JTAG support is required for dense telecom layouts. Compare against the 82P2288BBG8 variant to verify if the BCG package offers specific mechanical advantages for the assembly process. Ensure the 3V to 3.6V power domain aligns with the system's voltage regulation architecture.

Part Context

This part belongs to the 82P2288 family of high-performance telecommunication interface ICs from Renesas. It shares functional similarities with other members like the 82P2288BBG8 but differs in physical packaging. The family is widely utilized in legacy and modern digital carrier networks requiring precise clock recovery and framing capabilities.

Replacement Considerations

The IDT82P2288BBG8 is a documented alias for this component family. Verify pin-for-pin compatibility with existing designs using the 82P2288BBG8 before substitution. Consult the official PCN documents for any package or labeling changes that may affect mechanical integration.
