82P2281PFG8

Overview

The IDT82P2281 is an octal T1/E1/J1 long haul and short haul transceiver manufactured by Renesas Electronics Corporation. It integrates eight independent channels within a single package, supporting T1, E1, and J1 transmission standards. The device operates on a supply voltage ranging from 3V to 3.6V and draws a maximum current of 1.15A. It features an integrated adaptive equalizer, clock and data recovery (CDR), and receive jitter attenuator for signal integrity. Communication with the host system is facilitated via a Serial Peripheral Interface (SPI). The component is housed in an 80-lead Thin Quad Flatpack (TQFP) package measuring 14x14 mm, suitable for surface mount installation.

Feature Summary

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status as manufacturing revisions may alter environmental certifications. Ensure the source document matches the exact part number to avoid discrepancies in pinout or electrical specifications during procurement.

Selection Notes

Select this component when designing systems requiring multiple T1, E1, or J1 channels in a compact footprint. Evaluate power consumption requirements against the specified 1.15A maximum current draw. Verify that the host processor supports the required SPI interface protocol for configuration and monitoring tasks.

Part Context

This component belongs to the IDT82P228 family of high-performance telecom transceivers. It serves as a specialized interface solution for digital carrier networks. The device consolidates functions typically distributed across multiple discrete components, reducing board space and design complexity for telecommunications applications.

Replacement Considerations

The IDT82P2281PFG is listed as a direct replacement for the 82P2281PF variant.
