82V3355EDG8

Overview

The 82V3355EDG8 is a SuperSet Master clock generator manufactured by Renesas Electronics, belonging to the 82V3355 series. It is housed in a 64-pin TQFP package and operates on a 3.3 V supply voltage within an industrial temperature range of -40°C to +85°C. The device supports input frequencies up to 622.08 MHz via LVCMOS, LVDS, or LVPECL interfaces. It provides multiple output configurations compliant with ITU-T G.783 and Telcordia GR-253-CORE standards for SONET/SDH network synchronization.

Feature Summary

• Integrated SuperSet Master PLL solution for Stratum 3, SMC, 4E, and 4 clock applications
• Supports SONET/SDH, DWDM, and wireless base station timing requirements
• Accepts recovered clocks from STM-N/OC-n, PDH networks, or external references
• Configurable via serial interface or JTAG for flexible system integration

Applications

• SONET/SDH node timing synchronization
• DWDM equipment clock generation
• Wireless base stations (GSM, 3G)
• DSL concentrators and access networks

Procurement Notes

The 82V3355TFG variant is listed as discontinued by Renesas Electronics. Verification of the specific EDG8 suffix status against official discontinuance notices is required before procurement planning. Moisture sensitivity level 3 applies, necessitating proper storage and handling protocols during assembly.

Selection Notes

Select this component for designs requiring high-jitter compliance with GR-1244-CORE and GR-253-CORE standards. Ensure the design accommodates the 64-TQFP package dimensions (10.0 x 10.0 mm) and verifies compatibility with the specified 3.3 V power domain and supported input/output voltage levels.

Part Context

This part belongs to the IDT/Renesas 82V3355 family of synchronous Ethernet WAN PLLs. It serves as a specialized timing source for telecommunications infrastructure, replacing earlier discrete clock solutions with a single-chip integrated approach for improved performance and reduced board space in carrier-grade equipment.

Replacement Considerations

The 82V3355TFG is identified as a discontinued alternative within the same product line. Verify pinout and electrical parameter compatibility if considering legacy stock or cross-referencing with other 82V3355 variants.
