PI6CDBL401BZHIE

Overview

The PI6CDBL401BZHIE is a 4-output low power buffer designed for PCIe Gen1, Gen2, and Gen3 applications. It features an integrated Zero-Delay Buffer (ZDB) PLL and provides four differential outputs compatible with HCSL or LVDS standards. The device operates on a core supply voltage of 3.3V ±10% and supports output supply voltages of 1.8V, 2.5V, or 3.3V. It includes programmable output amplitude and slew rate settings via SMBus, along with individual output enables. The component is housed in a 32-TQFN package and supports industrial ambient operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Four differential outputs compliant with PCIe 3.0, 2.0, and 1.0 standards
• Integrated ZDB PLL with selectable High Bandwidth, Bypass, and Low Bandwidth modes
• Programmable output amplitude and slew rate via SMBus interface
• Three selectable SMBus addresses controlled by the SADR_tri pin

Applications

• PCIe 3.0/2.0/1.0 clock distribution systems
• Low power clock buffering for high-speed serial interfaces

Procurement Notes

Verify that the ordering suffix matches the required packaging format. The 'E' suffix indicates lead-free and green material compliance, while the 'X' suffix specifies tape and reel packaging. Confirm the specific package code ZH32 corresponds to the 32-contact Thin Quad Flat No-Lead form factor required for the target PCB layout.

Selection Notes

Select this component when a low-power solution for PCIe clock distribution is required. Ensure the design accommodates separate VDDO supply rails if utilizing 1.8V or 2.5V output levels. Verify that the input clock source meets the specified differential swing and slew rate requirements for reliable operation within the industrial temperature range.
