PI6CB33602ZLAIEX

Clock Buffers, Drivers Overview

The PI6CB33602ZLAIEX is a very low power PCIe clock buffer manufactured by Diodes Incorporated. It features six differential HCSL outputs with on-chip termination, supporting input frequencies of 100MHz, 50MHz, 125MHz, and 133.33MHz via SMBus configuration. The device operates on a nominal 3.3V supply voltage (3.135V to 3.465V) and utilizes an internal PLL for jitter performance compliant with PCIe Gen1 through Gen5 standards. It is housed in a 40-lead 5x5mm TQFN package.

Clock Buffers, Drivers Feature Summary

• Six differential low-power HCSL outputs with default 85Ω on-chip termination
• Supports 100MHz, 50MHz, 125MHz, and 133.33MHz input frequencies
• SMBus programmable slew rate, output amplitude, and individual output enable
• Differential output-to-output skew less than 50ps

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 component against the official Diodes Incorporated datasheet DS41291 Rev 6-2. Confirm that the ZLA suffix corresponds to the 40-contact TQFN package and the E/X suffixes indicate lead-free green packaging in tape and reel format. Ensure compatibility with industrial temperature ranges (-40°C to +85°C).

Clock Buffers, Drivers Selection Notes

Select this component when a low-jitter PCIe clock buffer with integrated termination is required to reduce external resistor count. The SMBus interface allows dynamic adjustment of slew rates and amplitudes for board optimization. Verify that the 3.3V supply voltage range aligns with the system design requirements.

Clock Buffers, Drivers Part Context

This part belongs to the PI6CB33 series of PCIe clock buffers from Diodes Incorporated. It is designed to fan out reference inputs to multiple differential outputs while maintaining signal integrity across high-speed interfaces. The device supports both strapping pin and SMBus configuration methods.

Clock Buffers, Drivers Replacement Considerations

Consult the manufacturer's documentation for direct replacements. Cross-reference specifications such as output count, package type, and electrical parameters before substituting.
