PI6C20800VE

Overview

The PI6C20800VE is a high-speed, low-noise differential clock buffer designed for Intel PCI Express chipsets. It distributes a differential SRC clock from the PI6C410B synthesizer to eight differential pairs of outputs with or without PLL support. The device operates on a single 3.3V supply (3.135V to 3.465V) and features HCSL input/output types. It supports 100-200MHz PLL mode and 100-400MHz bypass mode operation. Key electrical parameters include output-to-output skew less than 50ps and cycle-to-cycle jitter under 50ps. The component is housed in a 48-pin SSOP package.

Feature Summary

• Eight pairs of differential HCSL clock outputs
• Low skew (<50ps) and low cycle-to-cycle jitter (<50ps)
• Programmable PLL bandwidth and SMBus control interface
• Supports both PLL and Fanout operations

Applications

• Intel PCI Express chipset clock distribution
• High-speed data transmission systems requiring low jitter
• Server and storage backplane clocking

Procurement Notes

Verify the specific ordering suffix 'VE' corresponds to the 48-pin SSOP package as documented in the datasheet. Confirm that the component meets Pb-Free and Green manufacturing standards. Check for any Product Change Notifications (PCN) or End-of-Life (EOL) notifications issued by Diodes Incorporated or Pericom Semiconductor regarding this part number before finalizing procurement plans.

Selection Notes

Select the PI6C20800VE when an 8-channel differential clock buffer with integrated PLL capabilities is required for PCIe applications. Ensure the design accommodates the 3.3V power supply range and utilizes the SMBus interface for dynamic configuration. Consider the 48-pin SSOP footprint constraints during PCB layout. Verify compatibility with the upstream PI6C410B clock synthesizer for optimal system performance.

Part Context

The PI6C20800 series includes variants such as the PI6C20800AE (TSSOP package). The 'VE' suffix specifically denotes the 48-pin, 300-mil wide SSOP package form factor. This component belongs to the family of companion devices designed to work alongside the PI6C410B clock generator, providing fanout and buffering capabilities for complex motherboard architectures.
