PI49FCT3802LE

Clock Buffers, Drivers Overview

The PI49FCT3802LE is a 3.3V non-inverting clock buffer manufactured by Diodes Incorporated, packaged in a 16-pin TSSOP. It provides a 1:5 fanout with high-frequency operation exceeding 156 MHz. Key electrical parameters include a maximum propagation delay of 2.5 ns and output-to-output skew under 250 ps. The device features low duty cycle distortion (<250 ps) and supports capacitive loads from 10 pF to 50 pF. It operates within a supply voltage range of 3.0 V to 3.6 V and includes multiple VDD/GND pins for noise reduction.

Clock Buffers, Drivers Feature Summary

• High-speed 1:5 non-inverting buffer with frequency capability >156 MHz
• Low-skew performance (<250 ps) between any two output clocks
• Low duty cycle distortion (<250 ps) and propagation delay (<2.5 ns)
• 5V tolerant input compatible with standard CMOS/TTL levels

Clock Buffers, Drivers Applications

• Synchronous networking systems requiring tight skew distribution
• High-speed clock distribution where signal quality is critical
• Single point-to-point transmission line driving applications

Clock Buffers, Drivers Procurement Notes

Verify the 'E' suffix indicates Pb-free and Green packaging status as specified in the ordering information. Confirm the package code corresponds to the 16-pin TSSOP form factor. Ensure compatibility with the 3.3V supply voltage requirements and industrial temperature ranges if applicable.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:5 fanout is required instead of the 1:7 configuration offered by the PI49FCT3803. Choose the TSSOP package (L suffix) over QSOP for specific board layout constraints. Verify that the 5V tolerant input meets the system's logic level interface requirements.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT380x series of 3.3V compatible, high-speed, low-noise non-inverting clock buffers. The series targets networking applications needing low-jitter and high-frequency clock distribution. The PI49FCT3802 specifically handles 1:5 fanout, while the PI49FCT3803 handles 1:7 fanout.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT3803 serves as a functional alternative if a 1:7 fanout is acceptable. For pin-compatible replacements with different fanouts, verify specific electrical characteristics against the original design requirements.
