RC38612AXXXGN2#BB0

Overview

The RC38612AXXXGN2#BB0 is a single-circuit application-specific clock generator from Renesas Electronics, designed for Ethernet and SONET/SDH synchronization. It features five inputs and twelve outputs driven by an internal PLL. The device supports input signals including CML, CMOS, HCSL, LVDS, PECL, and crystal sources. Output configurations include CML, HCSL, HSTL, LVCMOS, LVDS, LVPECL, and SSTL. It operates with a maximum frequency of 1 GHz on a supply voltage range of 1.71 V to 3.465 V. The component is housed in a 72-VFQFPN package with an exposed pad and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports 5 differential inputs and 12 differential outputs via a single PLL circuit
• Compatible with diverse input types: CML, CMOS, HCSL, LVDS, PECL, and Crystal
• Provides flexible output formats: CML, HCSL, HSTL, LVCMOS, LVDS, LVPECL, and SSTL
• Maximum operating frequency reaches 1 GHz

Applications

• Ethernet network synchronization
• SONET/SDH timing applications

Procurement Notes

Verify the specific suffix 'BB0' against official Renesas documentation to confirm exact factory configuration or binning details. Ensure the design accommodates the 72-VFQFPN package thermal requirements due to the exposed pad. Confirm that the 1.71 V to 3.465 V supply range aligns with the target system power rails before procurement.

Selection Notes

Select this component when a high-frequency (up to 1 GHz) clock solution is required for Ethernet or SONET/SDH systems. It is suitable for designs needing mixed signal compatibility across multiple I/O standards like LVPECL and LVCMOS. Consider the 72-VFQFPN package size if board space allows for a 10x10 mm footprint.

Part Context

This part belongs to the RC38612AXXX series of application-specific clock generators. These devices are engineered to provide precise timing solutions for high-speed serial communication interfaces. The series utilizes a single PLL architecture to manage multiple output frequencies from various input sources.

Replacement Considerations

Consult Renesas technical support for direct pin-to-pin replacements within the same family. Verify that any substitute maintains the 5-input to 12-output ratio and supports the required 1 GHz frequency.
