RC38612AXXXGN2#KB0

Overview

The RC38612AXXXGN2#KB0 is a high-performance clock generator from Renesas Electronics, designed for Ethernet and SONET/SDH applications. It features five differential inputs and twelve outputs, supporting CML, HCSL, HSTL, LVCMOS, LVDS, and LVPECL output types. The device integrates eight PLLs and operates within a supply voltage range of 1.71V to 3.465V, with a maximum frequency of 1GHz. It functions in temperatures from -40°C to 85°C and is housed in a 72-VFQFN exposed pad package.

Feature Summary

• Supports five differential input formats including CML, CMOS, HCSL, LVDS, PECL, and Crystal.
• Provides twelve flexible output configurations across CML, HCSL, HSTL, LVCMOS, LVDS, and LVPECL.
• Integrates eight independent phase-locked loops (PLLs) for complex timing synthesis.
• Optimized for Ethernet and SONET/SDH network synchronization requirements.

Applications

• Ethernet network infrastructure
• SONET/SDH transmission systems

Procurement Notes

Verify the specific suffix 'XXX' against official documentation to confirm exact frequency options and configuration settings. Confirm RoHS compliance status through manufacturer datasheets before procurement. Ensure the 72-VFQFN thermal pad soldering process aligns with PCB layout guidelines for reliable surface mount installation.

Selection Notes

Select this component when designing systems requiring multiple independent clock domains derived from a single source. The eight PLL architecture allows for significant frequency translation and jitter management. Verify that the required output voltage levels match the available LVCMOS, LVPECL, or CML options to minimize external level-shifting components.

Part Context

This part belongs to the RC38612A series of VersaClock™ devices. These are specialized timing solutions intended for high-speed serial data transmission and telecommunications equipment. The family provides deterministic latency and low phase noise characteristics essential for maintaining signal integrity in dense digital environments.

Replacement Considerations

Check for updated Rev B or C silicon revisions which may offer improved electrical specifications or pin-compatible upgrades. Evaluate alternative Renesas models with fewer PLLs if cost reduction is necessary, provided the channel count remains sufficient for the design.
