5PB1104CMGK

Overview

The 5PB1104CMGK is a high-performance LVCMOS clock buffer manufactured by Renesas Electronics Corporation. It features a 1:4 input-to-output ratio with a maximum operating frequency of 200 MHz. The device operates within supply voltage ranges of 1.71V to 1.89V, 2.375V to 2.625V, and 3.135V to 3.465V. Packaged in an 8-VFQFN (2x2 mm) surface-mount format, it supports an extended industrial temperature range from -40°C to +105°C. The component utilizes LVCMOS input and output logic levels.

Feature Summary

• 1:4 Fanout Ratio: Distributes a single LVCMOS input clock signal to four independent LVCMOS outputs.
• High Frequency Operation: Supports clock frequencies up to 200 MHz for high-speed digital applications.
• Compact Packaging: Housed in an 8-UFDFN/VFQFN package measuring 2mm x 2mm for space-constrained designs.
• Industrial Temperature Range: Rated for reliable operation across temperatures from -40°C to +105°C.

Applications

• Clock distribution networks in industrial control systems
• Timing synchronization in automotive radar and LiDAR subsystems
• Fan-out buffering for high-speed data communication interfaces

Procurement Notes

Verify the specific suffix 'K' corresponds to the required tape-and-reel packaging configuration. Confirm that the 8-VFQFN footprint matches the PCB layout constraints. Ensure the selected supply voltage aligns with one of the three supported operational ranges. Check for RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a single-ended LVCMOS source requires fan-out to four loads without differential signaling. Compare against the 5PB1104PGGK if a TSSOP-8 package is preferred over the QFN form factor. Consider the 5PB1102 series if only two outputs are sufficient for the design requirements.

Part Context

This part belongs to the 5PB11xx family of ultra-low jitter LVCMOS buffers. These components are designed to replace legacy discrete transistor solutions or older buffer ICs in modern mixed-signal environments. The 5PB1104 variant specifically addresses the need for quad fan-out in compact footprints.

Replacement Considerations

Publicly documented parameter-equivalent substitutes include the 5PB1104CMGK/W and the 651SCMGI8. Verify pin compatibility and electrical specifications before substituting.
