PI6C20800SVEX

Overview

The PI6C20800SVEX is a PCI Express high-speed, low-noise differential clock buffer manufactured by Diodes Incorporated. It distributes the differential SRC clock from the PI6C410BS to eight differential pairs of HCSL outputs in a 48-pin SSOP package. The device supports both PLL and fanout operation with a maximum input frequency of 400 MHz and an output frequency up to 100 MHz in PLL mode. Operating voltage ranges from 3.135V to 3.465V, and it functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Eight pairs of differential HCSL clock outputs
• Programmable PLL bandwidth and phase jitter filter for PCIe applications
• Low skew (<50ps) and cycle-to-cycle jitter (<70ps)
• SMBus control for output enable, power management, and configuration

Applications

• PCI Express clock distribution for Intel server chipsets
• High-speed data transmission systems requiring low noise
• Server motherboard clocking architectures

Procurement Notes

Verify the 'V' suffix indicates the 48-pin SSOP package and 'E' denotes lead-free/green compliance. Confirm the 'X' suffix specifies tape and reel packaging. Check current availability as this component may be subject to end-of-life status or supply constraints.

Selection Notes

Select the PI6C20800SVEX for commercial temperature applications (0°C to 70°C). For industrial temperature requirements (-40°C to 85°C), consider the PI6C20800SI variant. Ensure the design accommodates the 48-SSOP footprint and SMBus interface requirements for configuration.

Part Context

This component belongs to the PI6C20800S series of PCIe clock buffers. It is designed to work in conjunction with the PI6C410BS clock generator. The SVEX designation specifically identifies the commercial grade version in the SSOP package with tape-and-reel packaging.

Replacement Considerations

The PI6C20800SAEX serves as a pin-compatible alternative using the TSSOP package. For industrial temperature grades, the PI6C20800SIAEX provides equivalent functionality in the TSSOP package.
