PI49FCT3802QE

Clock Buffers, Drivers Overview

The PI49FCT3802QE is a 1:5 non-inverting clock buffer manufactured by Diodes Incorporated, housed in a 16-pin QSOP package. It operates at a supply voltage of 3.3V ± 0.3V and supports input frequencies up to 156 MHz. Key electrical parameters include a maximum propagation delay of 2.5 ns, output-to-output skew under 250 ps, and duty cycle distortion below 250 ps. The device features 5V tolerant inputs and multiple VDD/GND pins for noise reduction, designed for synchronous networking applications.

Clock Buffers, Drivers Feature Summary

• High-speed 1:5 non-inverting clock buffer with >156 MHz frequency capability
• Low skew (<250ps) and low duty cycle distortion (<250ps)
• 5V tolerant input compatible with 3.3V supply voltage
• Multiple VDD and GND pins for enhanced noise reduction

Clock Buffers, Drivers Applications

• Synchronous networking systems requiring tight skew levels
• High-frequency clock distribution networks
• Low-jitter clock buffering for digital circuits

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 compliance as defined in the manufacturer's ordering information. Confirm that the industrial temperature range (-40°C to +85°C) meets system requirements, distinct from the commercial range (0°C to +70°C). Ensure static handling precautions are observed during assembly.

Clock Buffers, Drivers Selection Notes

Select the PI49FCT3802QE when a 1:5 fan-out ratio is required for 3.3V logic systems. Compare against the PI49FCT3803 if a 1:7 output configuration is needed instead. Consider the 16-pin QSOP footprint constraints versus the TSSOP option. Verify that the 2.5 ns max propagation delay and <250 ps skew specifications satisfy the timing budget of the target synchronous design.

Clock Buffers, Drivers Part Context

This component belongs to the PI49FCT380x series, which includes the PI49FCT3802 (1:5) and PI49FCT3803 (1:7) variants. Originally developed by Pericom Semiconductor Corporation, the product line is now managed by Diodes Incorporated. The series targets high-performance clock distribution needs in networking equipment.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT3802LE serves as a direct replacement within the same package family but utilizes TSSOP packaging instead of QSOP. For different fan-out requirements, the PI49FCT3803QE provides a 1:7 configuration in the identical 16-pin QSOP form factor.
