8T33FS6221ETGI

Clock Buffers, Drivers Overview

The Renesas 8T33FS6221ETGI is a high-speed fanout buffer designed for clock distribution in demanding electronic systems. It features a 2:20 input-to-output ratio, supporting differential HSTL and PECL inputs with PECL outputs. The device operates up to a maximum frequency of 2 GHz and is powered by dual voltage supplies ranging from 2.375V to 2.625V and 3.135V to 3.465V. Packaged in a 52-LQFP exposed pad (10x10 mm) for surface mount, it supports an operating temperature range of -40°C to 85°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific ETGI suffix against official documentation to confirm package and temperature specifications. Confirm availability status as this component may be subject to limited supply or discontinuation notices. Ensure compatibility with required voltage levels before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential clock source needs to drive twenty independent PECL loads. Verify that the system power rails align with the specified 2.5V and 3.3V ranges. Consider the 52-LQFP footprint for PCB layout constraints.

Clock Buffers, Drivers Part Context

This part belongs to the Renesas clock buffer family, engineered for signal integrity in high-frequency applications. It serves as a critical interface between primary clock generators and downstream logic components requiring precise timing synchronization.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible alternatives within the Renesas portfolio. Evaluate other 2:20 fanout buffers with matching PECL/HSTL support if sourcing is restricted.
