82P33731ABAG

Overview

The 82P33731ABAG is a specialized clock synthesizer and jitter cleaner manufactured by Renesas Electronics Corporation. Designed for high-performance networking applications, this integrated circuit supports Ethernet, SONET/SDH, and Stratum timing standards. It features a maximum operating frequency of 650MHz with two output channels. The device accepts differential inputs and provides differential outputs in CMOS, LVDS, or PECL formats. It operates on a supply voltage ranging from 1.71V to 3.465V and is housed in a 144-LBGA (13x13mm) package. The component includes an internal PLL and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Supports Ethernet, SONET/SDH, and Stratum synchronization requirements
• Features a 650MHz maximum frequency with 14:14 input-to-output ratio
• Provides differential CMOS, LVDS, or PECL outputs
• Integrates a Phase Locked Loop (PLL) for clock generation

Applications

• Synchronous Ethernet equipment clocks
• SONET/SDH network timing sources
• Stratum level clock distribution systems

Procurement Notes

Verify the current lifecycle status before procurement, as the component is listed as not recommended for new designs. Confirm the specific suffix 'ABAG' corresponds to the required 144-CABGA packaging and RoHS3 compliance. Check for any Product Change Notifications (PCN) regarding the all-dev label change dated December 1, 2022, to ensure compatibility with existing manufacturing processes.

Selection Notes

Select this component when designing systems requiring low-jitter clock synthesis for SONET/SDH or Ethernet interfaces. Ensure the design accommodates the 1.71V to 3.465V supply voltage range. Verify that the 144-LBGA footprint matches the PCB layout constraints. Consider the 14:14 I/O ratio to determine if the pin count aligns with the system's clock distribution needs.

Part Context

This part belongs to the 82P33731 series of synchronous equipment timing sources. It is distinct from other variants like the 82P33731ABAG8, which utilizes reel packaging instead of trays. The base product number is 82P33731, indicating its role within Renesas's broader portfolio of telecom interface ICs designed for precise network synchronization.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the 'not recommended for new design' status, alternative components should be evaluated based on functional equivalence in SONET/SDH and Ethernet timing applications.
