PI49FCT3803LE

Clock Buffers, Drivers Overview

The PI49FCT3803LE is a 3.3V compatible, high-speed, low-noise non-inverting clock buffer manufactured by Diodes Incorporated (formerly Pericom). It features a 1:7 input-to-output ratio and supports frequencies up to 156 MHz. The device provides output-to-output skew as low as 250ps and propagation delay under 2.5ns. It operates on a 3.3V supply voltage with an industrial temperature range of -40°C to +85°C. The component is housed in a 16-pin TSSOP package.

Clock Buffers, Drivers Feature Summary

• 1:7 non-inverting clock buffer configuration
• High-frequency operation up to 156 MHz
• Low output skew (<250ps) and duty cycle distortion (<250ps)
• 5V tolerant input capability

Clock Buffers, Drivers Applications

• Synchronous networking systems
• Clock distribution for high-speed digital circuits
• Low-jitter clock buffering applications

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'LE' indicates Pb-free and Green packaging status as defined in the manufacturer's ordering information table. Confirm the specific package type corresponds to the 16-pin TSSOP form factor required for the design. Ensure compatibility with the 3.3V supply voltage and industrial temperature range specifications.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:7 fan-out is required for synchronous systems. Compare against the PI49FCT3802 if a 1:5 ratio is sufficient. Ensure the design accounts for the 5V tolerant input feature if interfacing with higher voltage logic levels. Verify load capacitance requirements fall within the 10pF to 50pF specification.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT380x series, which includes the PI49FCT3802 (1:5 buffer). Both devices share similar electrical characteristics and are designed for low-skew clock distribution. The PI49FCT3803 specifically provides seven outputs from a single input, distinguishing it from the five-output variant.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT3802LE serves as a functional alternative if a 1:5 buffer ratio meets system requirements. Other members of the PI49FCT380x family may be considered for similar performance profiles.
