PI49FCT20802QE

Clock Buffers, Drivers Overview

The PI49FCT20802QE 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 accepts CMOS or TTL inputs and provides five CMOS/TTL outputs in a 16-QSOP surface-mount package. Designed for low-noise applications, it features output-to-output skew of less than 150ps and propagation delay under 3.5ns. It is characterized for industrial temperatures ranging from -40°C to 85°C.

Clock Buffers, Drivers Feature Summary

• High-speed operation with maximum frequency of 150 MHz
• Low output-to-output skew (< 150ps) and duty cycle distortion (< 300ps)
• Single 2.5V power supply with 3V tolerant inputs
• Multiple VDD and GND pins for noise reduction

Clock Buffers, Drivers Applications

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

Clock Buffers, Drivers Procurement Notes

Verify the component status before procurement as manufacturing data may indicate end-of-life conditions. Confirm the specific ordering suffix 'QE' corresponds to the 16-pin QSOP package with Pb-free and Green specifications. Ensure compatibility with the required 2.3V to 2.7V supply voltage range for the target application.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:5 fanout buffer is required for 2.5V logic systems. Compare against the PI49FCT20803 if seven outputs are needed instead of five. Consider the 16-QSOP package dimensions (0.154" width) for PCB layout constraints. Verify that the input signal levels meet the 3V tolerance requirement for interfacing with higher voltage sources.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT2080x family, which includes the PI49FCT20802 (1:5 buffer) and PI49FCT20803 (1:7 buffer). Both variants share similar electrical characteristics and are designed for networking applications. The 'QE' suffix specifically denotes the 16-pin QSOP package with environmental compliance.

Clock Buffers, Drivers Replacement Considerations

The PI49FCT20802LE serves as a pin-compatible alternative using a 16-pin TSSOP package. For applications requiring more outputs, the PI49FCT20803 provides a 1:7 configuration within the same series.
