PI6CB18601ZLAIEX

Clock Buffers, Drivers Overview

The PI6CB18601 is a very low power PCIe clock buffer manufactured by Diodes Incorporated. It provides six differential low-power HCSL outputs with integrated on-chip termination, eliminating the need for external resistors. The device operates on a nominal 1.8V supply and supports input frequencies of 100MHz, 50MHz, or 125MHz via SMBus configuration. It features individual output enables, programmable slew rates, and amplitude control for each output pair. The component meets PCIe Gen1 through Gen4 compliance standards with cycle-to-cycle jitter under 50ps and output skew under 50ps.

Clock Buffers, Drivers Feature Summary

• Six differential HCSL outputs with integrated on-chip termination

• Individual output enable pins for power management
• Programmable slew rate and output amplitude per channel
• Very low jitter performance compliant with PCIe Gen1/Gen2/Gen3/Gen4

Clock Buffers, Drivers Applications

• PCIe Gen1/Gen2/Gen3/Gen4 clock distribution
• Ethernet applications requiring 50MHz or 125MHz reference clocks

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'ZLAIE' corresponds to the 40-contact TQFN package in tape and reel format. Confirm that the 'I' suffix indicates industrial temperature grade operation (-40°C to +85°C). Ensure procurement channels are authorized to maintain product integrity and warranty coverage.

Clock Buffers, Drivers Selection Notes

Select this component when a low-power solution with integrated termination is required to reduce board space and BOM count. Use the SMBus interface for dynamic frequency selection between 50MHz, 100MHz, and 125MHz. Consider the individual OE# pins if independent power gating of specific output pairs is necessary for system efficiency.

Clock Buffers, Drivers Part Context

This part belongs to the PI6CB series of clock buffers from Diodes Incorporated (formerly Pericom). It is designed as a high-performance fanout buffer specifically optimized for high-speed serial interface standards like PCIe. The device integrates proprietary PLL technology to achieve low jitter while maintaining flexibility through strapping pins and SMBus configuration options.
