PI6C20800BIAE

Overview

The PI6C20800BIAE is a PCIe 3.0 compliant, high-speed, low-noise differential clock buffer designed for Intel server chipsets. It distributes the differential SRC clock from a PCI Express 3.0 clock generator to eight differential pairs of clock outputs, supporting either PLL or fanout operation. The device operates with a supply voltage range of 3.135V to 3.465V and supports an input frequency up to 400MHz in bypass mode. It features industrial temperature ratings (-40°C to +85°C) and includes phase jitter filtering capabilities.

Feature Summary

• PCIe 3.0 Compliant: Designed as a companion to PCI Express 3.0 clock generators for Intel server chipsets.
• Differential Output: Distributes one differential SRC clock input to eight differential pairs of HCSL clock outputs.
• Programmable PLL: Supports both PLL and fanout modes with programmable bandwidth settings (High/Low).
• Low Skew and Jitter: Features output-to-output skew less than 65ps and cycle-to-cycle jitter under 60ps.

Applications

• Intel Server Chipset Clock Distribution
• PCI Express 3.0 System Design
• High-Speed Differential Clock Buffering

Procurement Notes

Verify the specific suffix 'AE' indicates the 48-pin TSSOP package and 'I' denotes the industrial temperature grade. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the ordering code matches the required operational temperature range and packaging format.

Selection Notes

Select this component when a PCIe 3.0 compliant clock buffer with eight differential outputs is required for Intel server architectures. Consider the PI6C20800BAE if commercial temperature range (0°C to 70°C) suffices. Verify that the system design accommodates the 3.3V supply requirements and SMBus control interface for configuration.

Part Context

This part belongs to the PI6C20800B series of PCIe 3.0 clock buffers manufactured by Diodes Incorporated (formerly Pericom). The 'I' suffix specifies the industrial temperature variant, while 'AE' denotes the 48-pin wide TSSOP package. It serves as a critical timing distribution element in high-performance computing platforms.

Replacement Considerations

The PI6C20800BAE is the commercial temperature version of this component. Both share identical electrical characteristics and pinouts but differ in operating temperature ranges. No other direct substitutes are documented in the provided datasheet.
