PI6CEQ20200LIE

Overview

The PI6CEQ20200LIE is a PCIe Gen2/Gen3 zero-delay buffer manufactured by Diodes Incorporated. It features one HCSL differential input and two HCSL differential outputs, operating within a supply voltage range of 3.135V to 3.465V. The device supports input frequencies up to 110MHz and functions in an industrial temperature range of -40°C to +85°C. Key electrical specifications include a typical cycle-to-cycle jitter of 40ps and output-to-output skew under 10ps. It utilizes internal equalization for signal integrity and is housed in a 20-TSSOP package.

Feature Summary

• PCIe Gen2/Gen3 compliant zero-delay buffer with dual PLL bandwidth selection for spread-spectrum clocking tracking.
• Internal equalization technique enhances signal integrity for long-distance clock traces.
• Supports SMBus configuration via SCLK and SDATA pins for register control.
• Provides independent output enable controls (OE_0#, OE_1#) for CLK0 and CLK1 pairs.

Applications

• Servers
• Embedded computing systems
• Networking systems

Procurement Notes

Verify the ordering suffix 'I' confirms the -40°C to +85°C industrial temperature rating. Confirm whether the 'X' suffix is required for tape-and-reel packaging or if bulk quantities are available without it. Ensure the component is sourced from authorized distributors to guarantee authenticity and proper RoHS compliance documentation.

Selection Notes

Select this part when a single HCSL source must drive multiple PCIe Gen2/Gen3 destinations with low skew. Verify that the system requires the specific 3.3V supply voltage range and SMBus interface capabilities. Consider the 20-TSSOP footprint constraints during PCB layout design.

Part Context

This component belongs to the PI6CEQ20200 series of high-performance clock buffers. The 'LIE' suffix specifically denotes the Pb-free, Green compliant version packaged in a 20-pin TSSOP with extended industrial temperature support (-40°C to +85°C).

Replacement Considerations

Check datasheets for other PI6CEQ20200 variants such as PI6CEQ20200LE (commercial temp) or PI6CEQ20200LEX (reel). Ensure any substitute maintains the same HCSL I/O standards and SMBus compatibility.
