5PB1102CMGI8

Overview

The Renesas Electronics 5PB1102CMGI8 is a high-performance 1:2 LVCMOS clock buffer designed for precise clock distribution. 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 features very low pin-to-pin skew of less than 50 ps and additive jitter below 50 fs RMS. Packaged in an 8-UFDFN (2x2 mm) format, it includes integrated serial termination for 50 Ω channels and an Output Enable function. The component functions across an extended temperature range of -40 °C to +85 °C.

Feature Summary

• Ultra-low phase noise with < 50fs RMS additive jitter
• Very low pin-to-pin skew (< 50ps)
• Integrated serial termination for 50Ω channel impedance
• Supports Output Enable function for power management

Applications

• Automotive Radar systems
• LiDAR applications
• Industrial equipment requiring precise timing

Procurement Notes

Verify the specific suffix 'I8' corresponds to the tape-and-reel packaging configuration when sourcing. Confirm the operating temperature grade matches the design requirement, as the base model may offer different thermal ratings. Ensure the 8-UFDFN footprint aligns with the PCB layout specifications before finalizing procurement.

Selection Notes

Select this component when low jitter and skew are critical for signal integrity in 1:2 fanout scenarios. The 5PB1102CMGI8 is suitable for designs requiring LVCMOS outputs at frequencies up to 200 MHz. Consider the 8-pin DFN package constraints regarding thermal dissipation and soldering profiles during the selection process.

Part Context

This part belongs to the 5PB1102 series of high-performance clock buffers from Renesas Electronics. The series is characterized by its ability to distribute clock signals with minimal distortion. The CMGI8 designation specifies the commercial/industrial temperature variant housed in the small DFN package, distinguishing it from other package options like TSSOP or extended temperature versions.

Replacement Considerations

Direct substitutes include the 5PB1102CMGK8, which shares identical electrical characteristics but offers an extended temperature range up to +105 °C. Verify that the pinout and package dimensions remain compatible if swapping between these variants.
