PI49FCT20802LE

Clock Buffers, Drivers Overview

The PI49FCT20802LE is a 1:5 non-inverting clock buffer from the 49FCT series, manufactured by Diodes Incorporated. It operates on a 2.3V to 2.7V supply voltage and supports frequencies up to 150 MHz. The device features low skew of less than 150ps and low duty cycle distortion under 300ps. It accepts CMOS or TTL inputs and provides five CMOS/TTL outputs in a 16-TSSOP package.

Clock Buffers, Drivers Feature Summary

• High-speed operation with maximum frequency of 150 MHz
• Low output-to-output skew (< 150ps) and pulse skew (< 300ps)
• Multiple VDD and GND pins for noise reduction
• 3V tolerant input capability

Clock Buffers, Drivers Applications

• Networking applications requiring high-frequency clock distribution
• Synchronous systems needing low-jitter clock signals
• Low-skew clock buffering for digital circuits

Clock Buffers, Drivers Procurement Notes

Verify the component status as the datasheet originates from Pericom Semiconductor Corporation, which was acquired by Diodes Incorporated. Confirm RoHS compliance and Pb-free & Green packaging specifications directly with the manufacturer or authorized distributors before procurement.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring a single-input, five-output clock buffer operating at 2.5V. Ensure the design accommodates the 16-TSSOP package dimensions (4.40mm width). Verify that the load capacitance requirements fall within the specified range of 10pF to 25pF for optimal performance.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT2080x family, specifically designed for 2.5V networking applications. The 'L' suffix indicates the 16-pin TSSOP package, while the 'E' suffix denotes Pb-free and Green packaging. It is functionally similar to the QSOP version but offers a different form factor for surface-mount assembly.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT20802QE serves as a direct pin-compatible alternative in a 16-pin QSOP package. Other variants in the 49FCT series may offer different output counts or supply voltages but require careful verification of electrical characteristics and pinouts.
