PI6CEQ20200LE

Overview

The PI6CEQ20200LE is a PCIe Gen2/Gen3 zero-delay buffer featuring two HCSL outputs. It incorporates internal equalization to enhance signal integrity for long-distance clock distribution. The device operates on a 3.135V to 3.465V supply with a maximum frequency of 110MHz. Key electrical specifications include cycle-to-cycle jitter of 40ps typical and output-to-output skew under 10ps. It supports dual PLL bandwidth selection for spread-spectrum clocking tracking and includes SMBus control capabilities.

Feature Summary

• PCIe Gen2/Gen3 compliant zero-delay buffer with internal equalization
• Two differential HCSL outputs with <10ps output-to-output skew
• Dual PLL bandwidth selection (Low: 0.25-1 MHz, High: 1.3-3 MHz)
• Cycle-to-cycle jitter of 40ps typical; RMS phase jitter up to 3.1ps

Applications

• Servers
• Embedded computing systems
• Networking systems

Procurement Notes

Verify the ordering suffix against the manufacturer's datasheet to confirm package type and temperature range. The 'LE' suffix indicates a Pb-free, Green 20-pin TSSOP package with a commercial operating temperature range of 0°C to 70°C. Confirm whether tape-and-reel packaging is required by checking for an additional 'X' suffix in the part number.

Selection Notes

Select this component for applications requiring low-jitter clock buffering for PCIe Gen2 or Gen3 interfaces. Ensure the design environment stays within the commercial temperature range of 0°C to 70°C. For industrial temperatures (-40°C to 85°C), consider the LI variant. Verify that the system requires HCSL output levels and SMBus configuration support.

Part Context

This component belongs to the Pericom PI6CEQ series of high-performance clock buffers. It is designed specifically to meet the stringent jitter and signal integrity requirements of PCI Express standards. The device integrates equalization techniques to compensate for channel loss, making it suitable for complex motherboard layouts.
