5PB1102CMGK8

Overview

The Renesas 5PB1102CMGK8 is a high-performance 1:2 LVCMOS clock buffer designed for low jitter applications. 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 an additive phase jitter of less than 50 fs RMS and very low pin-to-pin skew under 50 ps. Packaged in an 8-lead DFN (COL) format measuring 2.0 x 2.0 mm, it includes integrated serial termination for 50 Ω channels. The component functions across an extended temperature range from -40 °C to +105 °C and incorporates an Output Enable function.

Feature Summary

• Ultra-low additive jitter (< 50 fs RMS) and pin-to-pin skew (< 50 ps)
• Integrated serial termination for 50 Ω channel impedance
• Operates on 1.8 V to 3.3 V supply with 200 MHz maximum frequency
• Extended industrial temperature range (-40 °C to +105 °C)

Applications

• Automotive Radar systems
• LiDAR applications
• Industrial equipment requiring precise clock distribution

Procurement Notes

Verify the specific suffix K8 indicates reel packaging when sourcing. Confirm the extended temperature grade (+105 °C) matches design requirements compared to the standard grade variants. Check current availability status as stock levels fluctuate. Ensure the 8-DFN package dimensions align with PCB footprint constraints.

Selection Notes

Select this component for designs requiring minimal jitter addition in LVCMOS clock networks. The 1:2 fan-out ratio suits single-source dual-load topologies. Verify that the 50 Ω integrated termination meets the transmission line requirements without external resistors. Compare against the CMGI8 variant if the standard temperature range (-40 °C to 85 °C) suffices for the application.

Part Context

This part belongs to the 5PB1102 series of high-performance clock buffers manufactured by Renesas Electronics. The series offers various package options including TSSOP and DFN, with different temperature grades denoted by suffixes. The CMGK8 specifically identifies the 8-lead DFN package configuration with the extended operating temperature range.

Replacement Considerations

The 5PB1102CMGI8 serves as a functional alternative within the same family but operates within a limited temperature range of -40 °C to 85 °C instead of the extended -40 °C to +105 °C range found in the CMGK8 variant.
