PI6C20800BIAEX

Overview

The PI6C20800BIAEX is a PCIe 3.0 compliant, high-speed, low-noise differential clock buffer manufactured by Diodes Incorporated. Designed as a companion to Intel server chipset PCI Express 3.0 clock generators, it distributes the differential SRC clock to eight differential pairs of HCSL outputs. The device supports both PLL and fanout operations, with an input frequency range up to 400 MHz in bypass mode. It operates on a single 3.3V supply (3.135V to 3.465V) within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include output-to-output skew less than 60ps and cycle-to-cycle jitter under 60ps.

Feature Summary

• PCIe 3.0 Compliant: Includes phase jitter filtering for PCIe 3.0 applications.
• Eight Differential Outputs: Distributes one differential input to eight differential HCSL output pairs.
• Low Skew and Jitter: Output-to-output skew is less than 60ps; cycle-to-cycle jitter is less than 60ps.
• SMBus Control: Supports indexed block read/write protocols for output enable, tristate control, and power management.

Applications

• Intel Server Chipset Clock Distribution
• PCI Express 3.0 System Designs

Procurement Notes

Verify the component against the official datasheet DS43445 Rev 1-2 to confirm compliance with EU RoHS 2015/863/EU directives. Ensure the package matches the 48-pin TSSOP specification. Confirm that the industrial grade suffix 'I' aligns with the required operating temperature range of -40°C to +85°C before finalizing procurement specifications.

Selection Notes

Select the PI6C20800BIAEX when an industrial temperature rating (-40°C to +85°C) is required for PCIe 3.0 clock distribution. Choose this part over the commercial variant if the application environment exceeds standard commercial limits. Verify that the system requires SMBus programmability for dynamic output control and power management features.

Part Context

This component belongs to the PI6C20800B series of PCIe clock buffers. The 'I' suffix specifically denotes the Industrial temperature grade variant, distinguishing it from the commercial version which typically operates between 0°C and 70°C. Both variants share identical electrical performance metrics regarding jitter, skew, and interface capabilities.

Replacement Considerations

The PI6C20800BAEX serves as the commercial-grade alternative to the PI6C20800BIAEX. Both parts are pin-compatible and functionally identical except for their specified operating temperature ranges. No other direct substitutes are documented in the provided manufacturer data.
