PI6CBF18501ZLAIEX

Clock Buffers, Drivers Overview

The PI6CBF18501 is a very low power 5-output PCIe fanout buffer with on-chip termination. It accepts a differential HCSL input and provides five differential low-power HCSL outputs. The device operates at a nominal 1.8V supply voltage (1.7V to 1.9V) and supports frequencies up to 200 MHz. Key electrical parameters include a maximum propagation delay of 4.5 ns, cycle-to-cycle jitter under 50 ps, and output-to-output skew under 50 ps. It features individual output enables and SMBus-configurable slew rates and amplitudes.

Clock Buffers, Drivers Feature Summary

• SMBus interface for programmable slew rate and output amplitude control
• Supports PCIe Gen1 through Gen4 standards
• Individual active-low output enable pins for power management

Clock Buffers, Drivers Applications

• PCIe clock distribution in server and storage systems
• High-speed digital board clock fanout
• Industrial temperature range (-40°C to 85°C) applications

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix when sourcing. The 'ZLAIE' variant indicates a 40-lead TQFN package, industrial temperature rating, lead-free/green status, and tape/reel packaging. Confirm the exact suffix matches the required pin 1 location and reel specifications before procurement.

Clock Buffers, Drivers Selection Notes

Select this component for designs requiring low-jitter clock distribution compliant with PCIe Gen1/2/3/4. Ensure the design accommodates the 1.8V core supply and 1.05V to 1.8V output supply. Utilize the SMBus interface if dynamic adjustment of slew rates or amplitudes is required to optimize signal integrity.
