5P83908NDGK

Overview

The 5P83908NDGK is a high-performance clock fanout buffer manufactured by Renesas Electronics. It accepts a crystal input and provides eight LVCMOS outputs with a 1:8 distribution ratio. The device supports maximum frequencies of 200 MHz and operates on a supply voltage ranging from 1.71 V to 3.465 V. It features a maximum propagation delay of 6 ns and functions within an operating temperature range of -40°C to +105°C. The component is housed in a surface-mount 20-VFQFN package with an exposed pad, measuring 3x3 mm.

Feature Summary

• Provides one-to-eight clock signal distribution for system synchronization
• Accepts direct crystal input without requiring external oscillators
• Delivers low-voltage CMOS output signals compatible with standard logic levels

Applications

• High-speed digital system clock distribution networks
• Multi-component synchronization in embedded systems
• Fanout buffering for memory and processor clock lines

Procurement Notes

Verify the specific suffix NDGK to confirm the 20-VFQFN package configuration, as other suffixes indicate different physical footprints. Ensure the application environment remains within the specified -40°C to +105°C operational temperature limits. Confirm that the power supply voltage stays strictly between 1.71 V and 3.465 V to prevent device malfunction or damage during operation.

Selection Notes

Select this component when a single crystal source must drive multiple downstream loads simultaneously. The 1:8 ratio makes it suitable for distributing a master clock to several synchronous devices. Consider the 200 MHz frequency limit and LVCMOS output compatibility when matching requirements against connected circuitry specifications.

Part Context

This part belongs to the 5P83908 series of mixed-signal clock buffers designed for high-performance applications. It serves as a critical timing element in complex electronic architectures where precise clock distribution is required. The series offers various package options to accommodate different board space and thermal management constraints.

Replacement Considerations

The 5P83908PGGK is a confirmed substitute offering identical electrical performance but utilizing a 20-TSSOP package instead of the QFN form factor.
