PI6CEQ20200LEX

Overview

The PI6CEQ20200LEX is a PCIe Gen2/Gen3 zero-delay buffer manufactured by Diodes Incorporated, packaged in a 20-TSSOP. It features two HCSL outputs and an internal PLL for cycle-to-cycle jitter of 40ps (typical). The device operates on a 3.135V to 3.465V supply within a commercial temperature range of 0°C to 70°C. It supports SMBus configuration and includes dual PLL bandwidth selection for spread-spectrum clocking tracking.

Feature Summary

• PCIe Gen2/Gen3 compliant zero-delay buffer with internal equalization
• Two differential HCSL outputs with output-to-output skew under 10ps
• Dual PLL bandwidth selection for SSC tracking
• Cycle-to-cycle jitter of 40ps typical

Applications

• Servers
• Embedded computing systems
• Networking systems

Procurement Notes

Verify the ordering suffix 'LEX' confirms the Tape & Reel packaging format and the 'E' indicates Pb-free/Green compliance. Confirm the base model PI6CEQ20200 matches the required commercial temperature grade (0°C to 70°C) rather than the industrial variant (-40°C to 85°C). Cross-reference the specific revision level if legacy documentation is used.

Selection Notes

Select this component for applications requiring low-skew buffering of PCIe reference clocks where signal integrity over long traces is critical due to built-in equalization. Ensure the design accommodates the 3.3V supply voltage and utilizes the SMBus interface for dynamic configuration of PLL bandwidth and output enables.

Part Context

This part belongs to the Pericom/PI6CEQ family of high-performance clock buffers. The 'LEX' suffix specifically denotes the 20-pin TSSOP package supplied in a tape and reel format, suitable for automated surface-mount assembly processes.

Replacement Considerations

The PI6CEQ20200LIEX serves as the industrial temperature grade replacement for the same functional specifications. Verify pin compatibility and thermal requirements when substituting between commercial and industrial grades.
