RC32308A001GNE#BB0

Clock Buffers, Drivers Overview

The RC32308A001GNE#BB0 is a FemtoClock 3 ultra-low noise clock synthesizer manufactured by Renesas Electronics. It provides eight differential outputs with frequencies ranging from 0.001 MHz to 1000 MHz. The device operates on a single 1.8V core voltage and supports input frequencies up to 1000 MHz via crystal, LVPECL, HCSL, LVDS, CML, or LVCMOS interfaces. It features low power consumption, dissipating less than 1.2W in full configuration mode. The component is designed for high-performance applications requiring precise timing synchronization.

Clock Buffers, Drivers Feature Summary

• Ultra-low jitter performance with typical RMS phase jitter as low as 50fs (12kHz-20MHz range) at 312.5MHz output frequency.
• Supports four independent frequency domains using three Fractional Output Dividers (FOD).
• Flexible startup configurations allowing automatic loading from external EEPROM or up to four OTP memories.
• Dual communication interface options supporting both SPI and I2C protocols.

Clock Buffers, Drivers Applications

• 100G/200G/400G/800G SerDes data center reference clocks
• 56G/112G PAM4 SerDes clock synthesis
• Data Center Top-of-Rack (ToR) and Leaf switches
• Ethernet switches and routers

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix BB0 against official Renesas documentation to confirm package type and moisture sensitivity level details. Ensure compatibility with the required output voltage levels and input signal types before integration. Confirm that the factory-configured settings meet the target application's frequency requirements without additional programming.

Clock Buffers, Drivers Selection Notes

Select this component when ultra-low jitter is critical for 100G+ Ethernet or PCIe Gen 6 compliance. The RC32308A variant offers eight differential outputs; choose higher pin-count variants if twelve outputs are required. Verify that the system design can accommodate the 1.8V core supply and 3.3V serial interface voltage requirements.

Clock Buffers, Drivers Part Context

This part belongs to the FemtoClock 3 series, which includes models like RC223xxA. While sharing similar low-jitter technologies, the RC32308A specifically provides eight differential outputs compared to other family members that may offer different output counts or pin configurations. It is distinct from general-purpose clock generators due to its extreme performance specifications.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes within the FemtoClock 3 family include the RC22308A or RC22312A, depending on whether eight or twelve outputs are needed. Cross-model replacements require verification of pinout compatibility and output count differences. No alternative manufacturer parts are confirmed in the provided source material.
