5PB1104CMGK8

Overview

The 5PB1104CMGK8 is a high-performance clock buffer from the Renesas 5PB11xx series, designed for low-jitter LVCMOS applications. It features four outputs driven by a single input, supporting maximum frequencies up to 200 MHz. The device operates within a supply voltage range of 1.71 V to 3.465 V and includes integrated serial termination for 50 Ω channels. Key electrical specifications include a maximum propagation delay of 2.4 ns and an operating temperature range from -40°C to +105°C. It is housed in an 8-DFN package.

Feature Summary

• Four-output LVCMOS fanout buffer with 1:4 ratio
• Maximum operating frequency of 200 MHz
• Integrated serial termination for 50 Ω impedance matching
• Extended industrial temperature range (-40°C to +105°C)

Applications

• Industrial automation systems requiring precise clock distribution
• Automotive radar and LiDAR signal processing
• High-speed data acquisition equipment

Procurement Notes

Verify the specific suffix 'CMGK8' against official Renesas documentation to confirm the reel quantity and tape-and-reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory status can vary by production batch and region.

Selection Notes

Select this component when a single clock source must drive four distinct LVCMOS loads with minimal skew and jitter. Ensure the design supports the 1.71 V to 3.465 V supply range and utilizes the 8-DFN footprint. Consider the 2.4 ns max propagation delay for timing budget calculations in high-frequency circuits.

Part Context

This part belongs to the 5PB11xx family of ultra-low jitter LVCMOS buffers originally developed by IDT and now manufactured by Renesas Electronics. The family provides various output configurations (1:2, 1:4, 1:10) optimized for noise-sensitive digital systems. The CMGK8 suffix denotes the specific surface-mount DFN packaging and reel configuration.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the 5PB1104CMGK (tube packaging) or other variants in the 5PB11xx series. Verify that alternative parts match the 200 MHz frequency limit and 50 Ω termination requirements.
