PI6CB18200ZDIEX

Clock Buffers, Drivers Overview

The PI6CB18200ZDIEX is a very low power PCIe clock buffer manufactured by Diodes Incorporated. It features a single HCSL differential input and two differential HCSL outputs, supporting frequencies of 50MHz, 100MHz, and 125MHz via SMBus configuration. The device operates on a 1.8V supply voltage with a maximum propagation delay of 4.5ns in PLL bypass mode. It incorporates a proprietary PLL design to achieve cycle-to-cycle jitter below 50ps, meeting PCIe Gen1 through Gen4 requirements. The component is housed in a 24-lead TQFN package.

Clock Buffers, Drivers Feature Summary

• Supports 50MHz, 100MHz, and 125MHz output frequencies via SMBus or strapping pins
• Very low differential cycle-to-cycle jitter (<50ps) and output-to-output skew (<50ps)
• Individual active-low output enable (OE#) for each differential pair
• Programmable slew rate and output amplitude settings

Clock Buffers, Drivers Applications

• PCIe Gen1/Gen2/Gen3/Gen4 clock distribution
• Ethernet applications requiring 50MHz or 125MHz reference clocks

Clock Buffers, Drivers Procurement Notes

Verify the datasheet revision DS40224 Rev 6-2 against the specific manufacturing lot. Confirm compliance with EU RoHS directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. Ensure the ordering suffix 'X' corresponds to the Tape & Reel packaging format required for automated assembly processes.

Clock Buffers, Drivers Selection Notes

Select this component when a low-power solution for PCIe or Ethernet clock fanout is required. The device supports both hardware strapping and SMBus configuration for frequency and amplitude adjustments. Verify that the system environment temperature falls within the -40°C to +85°C industrial operating range specified for this part number.

Clock Buffers, Drivers Part Context

This part belongs to the PI6CB18200 product line from Diodes Incorporated. It is specifically designed as a slave-only device utilizing a 7-bit SMBus address (DA hex). The ZDIEX suffix indicates a 24-contact Very Thin Quad Flat No-Lead (TQFN) package with a top-right corner pin 1 location, supplied in tape and reel quantities.
