PI6CB33602ZLAIEX-13R

Clock Buffers, Drivers Overview

The PI6CB33602ZLAIEX-13R is a very low power PCIe clock buffer manufactured by Diodes Incorporated. It features one differential HCSL input and six differential low-power HCSL outputs with on-chip termination. The device operates at a nominal 3.3V supply voltage and supports frequencies of 50MHz, 100MHz, 125MHz, and 133.33MHz via SMBus configuration. It utilizes an internal PLL to achieve very low jitter compliant with PCIe Gen1 through Gen5 standards. The component is housed in a 40-lead 5x5mm TQFN package.

Clock Buffers, Drivers Feature Summary

• Six differential low-power HCSL outputs with integrated on-chip termination (default ZOUT = 85Ω)
• Supports 50MHz, 100MHz, 125MHz, and 133.33MHz input frequencies via SMBus
• Very low differential cycle-to-cycle jitter (<50ps) compliant with PCIe Gen1/Gen2/Gen3/Gen4/Gen5
• Individual output enable pins for each differential pair

Clock Buffers, Drivers Applications

• PCIe Gen1/Gen2/Gen3/Gen4/Gen5 clock distribution
• Ethernet applications requiring 50MHz, 125MHz, or 133.33MHz clocks
• Spread spectrum tolerant clock buffering

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix '-13R' against official documentation to confirm tape orientation details. Ensure that the required frequency selection and SMBus address configurations align with the system design requirements before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended or differential HCSL reference clock requires fan-out to six differential loads. Consider the on-chip termination feature to reduce external resistor count. Verify that the operating temperature range (-40°C to 85°C) meets the environmental specifications of the target application.

Clock Buffers, Drivers Part Context

This part belongs to the PI6CB33 series of clock buffers from Diodes Incorporated. It is designed as a slave-only device communicating via SMBus. The 'ZLA' package code indicates a 40-contact Very Thin Quad Flat No-Lead (TQFN) form factor.

Clock Buffers, Drivers Replacement Considerations

Consult the manufacturer's datasheet for officially confirmed substitute part numbers. Generic cross-references should be avoided without verifying electrical parameters and pin compatibility.
