5P83904CMGK

Overview

The 5P83904CMGK is a high-performance clock buffer manufactured by Renesas Electronics. It functions as a 1-to-4 fanout buffer with a crystal input and LVCMOS outputs. The device accepts fundamental mode crystals in the 10 MHz to 40 MHz range and provides four LVCMOS clock outputs. Key electrical specifications include a maximum propagation delay of 6 ns, an operating supply voltage range of 1.71 V to 3.465 V, and a typical operating current of 12.1 mA. It is housed in a QFN-16 package and supports an industrial temperature range from -40°C to +105°C.

Feature Summary

• 1:4 Crystal Input to LVCMOS Output Fanout Buffer
• Synchronous Glitch-Free Output Enable Function
• Best-in-Class Phase Noise Performance
• Operating Voltage Range of 1.71 V to 3.465 V

Applications

• High-performance clock distribution systems
• Systems requiring low phase noise clock sources
• Industrial and commercial electronic equipment

Procurement Notes

Verify the specific suffix 'CMGK' against the official datasheet to confirm the package type (QFN-16) and temperature grade. Ensure compatibility with the required crystal frequency range of 10 MHz to 40 MHz. Check for RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement.

Selection Notes

Select this component when a single crystal input needs to drive four LVCMOS loads with minimal skew. The glitch-free output enable feature is critical for applications requiring clean clock transitions during power-up or shutdown. Verify that the system supply voltage falls within the 1.71 V to 3.465 V range and that the thermal requirements fit the -40°C to +105°C operational window.

Part Context

This part belongs to the 5P8390x family of mixed-signal clock buffers. The 'C' in the part number typically denotes the industrial temperature range (-40°C to +105°C), while 'MGK' specifies the QFN-16 package variant. It serves as a specialized timing solution distinct from general-purpose logic buffers due to its integrated crystal input handling capabilities.

Replacement Considerations

Consult the official Renesas selection guide for direct pin-compatible alternatives within the 5P8390x series. Verify if other suffixes such as 'PGGK' (TSSOP-16) meet mechanical constraints. No third-party substitutes are confirmed in public documentation; cross-referencing with the manufacturer's obsolescence notices is recommended.
