5PB1108CMGI8

Overview

The Renesas Electronics 5PB1108CMGI8 is a high-performance LVCMOS clock buffer featuring a 1:8 fan-out configuration. It operates within a supply voltage range of 1.71 V to 3.465 V and supports maximum input frequencies up to 200 MHz. The device is housed in an 8-UFDFN package with dimensions of 2x2 mm. It functions reliably across an extended temperature range from -40°C to +105°C, ensuring stability in demanding industrial environments.

Feature Summary

• 1:8 LVCMOS fan-out buffer architecture
• Maximum operating frequency of 200 MHz
• Supply voltage range of 1.71 V to 3.465 V
• Extended industrial temperature range (-40°C to +105°C)

Applications

• Industrial applications requiring precise clock distribution
• Automotive radar systems
• LiDAR sensor modules

Procurement Notes

Verify the specific suffix 'CMGI8' against official Renesas documentation to confirm the package type (8-UFDFN) and temperature grade (+105°C). Ensure compatibility with existing PCB footprints for the 2x2 mm DFN form factor. Confirm RoHS compliance status through current datasheets prior to integration.

Selection Notes

Select this component when a single clock source must drive eight downstream LVCMOS loads with minimal skew. Compare against the 5PB1102 (1:2) or 5PB1104 (1:4) variants if fewer outputs are sufficient. Verify that the 200 MHz frequency requirement aligns with system timing constraints and that the 1.8V to 3.3V supply rail is available.

Part Context

This part belongs to the 5PB1108 series of high-performance clock buffers from Renesas Electronics. The series includes variants with different output counts and packaging options, such as the PGGI (TSSOP) and CMGK (extended temp) versions. The CMGI8 specifically denotes the 8-output configuration in the compact DFN package optimized for space-constrained designs.

Replacement Considerations

Direct pin-compatible replacements include other 5PB1108 variants like the 5PB1108PGGI (TSSOP-16) if package changes are acceptable. Cross-reference with the 5PB1102 or 5PB1104 if reduced fan-out meets design needs. Verify electrical parameters against competitor LVCMOS buffers before substitution.
