PI49FCT3803QE

Clock Buffers, Drivers Overview

The PI49FCT3803QE is a 3.3V compatible, high-speed, low-noise non-inverting clock buffer designed for networking applications requiring low-skew and low-jitter clock distribution. It features a 1:7 configuration with seven outputs driven by a single input. The device supports input frequencies up to 156 MHz and provides output-to-output skew as low as 250ps. Key electrical parameters include a maximum propagation delay of 2.5ns, low duty cycle distortion under 250ps, and a quiescent supply current of 30µA. It operates within a commercial temperature range of 0°C to +70°C and an industrial range of -40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'Q' corresponds to the 16-pin QSOP package and 'E' indicates Pb-free and Green status as defined in the manufacturer's ordering information. Confirm that the component meets RoHS compliance requirements if applicable to the target assembly process. Ensure the voltage supply matches the specified 3.3V ± 0.3V operating range.

Clock Buffers, Drivers Selection Notes

Select the PI49FCT3803QE when a 1:7 fan-out ratio is required for synchronous systems. Compare against the PI49FCT3802 if only five outputs are needed. Consider the 16-pin QSOP package constraints regarding board space and thermal dissipation. Verify that the 5V tolerant inputs align with the source logic levels in the design.

Clock Buffers, Drivers Part Context

This component belongs to the PI49FCT380x series of 3.3V Fast CMOS buffers produced using advanced submicron CMOS technology. The series includes the PI49FCT3802 (1:5 buffer) and the PI49FCT3803 (1:7 buffer). These devices are engineered to provide industry-leading speed grades and low noise performance for demanding clock distribution tasks.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT3802QE serves as a functional alternative if only five outputs are required. For legacy replacements, verify compatibility with older PI49FCT380x variants, noting potential differences in packaging or lead content depending on the specific revision.
