PI6CB18200ZDIEX-13R

Clock Buffers, Drivers Overview

The PI6CB18200ZDIEX-13R is a very low power PCIe clock buffer manufactured by Diodes Incorporated. It features two differential HCSL outputs and operates on a single 1.8V supply voltage (1.7V to 1.9V). The device supports input frequencies of 50MHz, 100MHz, and 125MHz via SMBus configuration. Key electrical parameters include a propagation delay of up to 4500ps in PLL bypass mode and 200ps in PLL mode. Differential cycle-to-cycle jitter is less than 50ps, with output-to-output skew under 50ps. It is housed in a 24-lead TQFN package.

Clock Buffers, Drivers Feature Summary

• Very Low Power: Operates at 1.8V with typical supply current of 10mA at 100MHz.
• Low Jitter Performance: Meets PCIe Gen1/Gen2/Gen3/Gen4 requirements with <50ps cycle-to-cycle jitter.
• Flexible Configuration: Supports strapping pins or SMBus for frequency selection (50/100/125MHz), slew rate, and amplitude control.
• Individual Output Enable: Separate OE# pins allow independent power management for each output pair.

Clock Buffers, Drivers Applications

• PCI Express (Gen1 through Gen4) clock distribution
• Ethernet applications requiring 50MHz or 125MHz reference clocks
• High-speed digital systems requiring low jitter fanout buffers

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix '-13R' corresponds to the specific tape and reel packaging orientation (Top Left Corner Pin 1 location) as defined in the datasheet. Confirm that the required frequency and jitter specifications align with the target application's compliance standards before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a 1.8V supply is available and low power consumption is critical. Ensure the system requires only two differential outputs. If higher output counts or different supply voltages are needed, consider other members of the PI6CB family. Verify SMBus interface compatibility if dynamic configuration is required.
