PI6C20800BAE

Overview

The PI6C20800BAE 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 with or without PLL. The input SRC clock can be divided by 2 when SRC_DIV# is LOW. The clock outputs are controlled by input selection of SRC_STOP#, PWRDWN# and SMBus, SCLK and SDA. When input of either SRC_STOP# or PWRDWN# is LOW, the output clocks are Tristated. When PWRDWN# is LOW, the SDA and SCLK inputs must be Tristated.

Feature Summary

• PCIe 3.0 compliant phase jitter filter
• Eight pairs of differential HCSL clock outputs
• Low skew < 50ps (PI6C20800B), <60ps (PI6C20800BI)
• Low Cycle-to-cycle jitter < 60ps

Applications

• Intel server chipset companion clock distribution
• PCI Express 3.0 clock generation systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and temperature range. The 'AE' suffix indicates a 48-pin TSSOP package that is Pb-Free and Green. Ensure compatibility with the required operating temperature range for the application.

Selection Notes

Select the PI6C20800BAE for commercial temperature applications (0°C to 70°C). For industrial temperature requirements (-40°C to 85°C), choose the PI6C20800BIAE variant instead. Both share the same electrical characteristics but differ in their qualified operating temperature ranges.

Part Context

This component belongs to the Pericom PI6C20800B series of PCIe 3.0 clock buffers. It serves as a critical interface between the system clock generator and multiple downstream components requiring synchronized differential clock signals in high-performance computing environments.

Replacement Considerations

For industrial temperature operation, use PI6C20800BIAE. For tape and reel packaging, add an 'X' suffix to the part number (e.g., PI6C20800BAEX).
