PI49FCT3807AQEX

Clock Buffers, Drivers Overview

The PI49FCT3807AQEX is a 3.3V Fast CMOS clock driver manufactured by Diodes Incorporated, featuring a 1-to-10 fanout configuration with one input and ten outputs. It operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range of –40°C to +85°C. The device provides ultra-low skew of 0.35ns typ and propagation delays between 1.5ns and 4.0ns max at CL=15pF. It accepts TTL-compatible inputs and drives CMOS outputs, ensuring low noise levels and minimal duty cycle distortion for clock distribution applications.

Clock Buffers, Drivers Feature Summary

• 1:10 Fanout Configuration: Distributes a single clock signal to ten independent output lines.
• Ultra-Low Skew: Achieves typical package skew (tSK(p)) of 0.35ns and inter-package skew of 0.75ns.
• TTL/CMOS Compatibility: Inputs are TTL compatible while outputs drive standard CMOS loads.
• Low Power Consumption: Quiescent current is typically 30µA.

Clock Buffers, Drivers Applications

• Clock distribution in high-speed digital systems.
• Signal distribution networks requiring low jitter and skew.
• Bus architectures utilizing 3-state control for clock busing.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'Q' corresponds to the 20-pin 150-mil wide QSOP package. Confirm the 'E' suffix indicates Pb-free and Green status. Ensure the 'X' suffix matches the required tape and reel packaging format. Check for RoHS3 compliance requirements against the datasheet specifications.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:10 non-inverting clock buffer is required with tight skew constraints. The QSOP package is suitable for space-constrained surface mount designs. Verify that the load capacitance does not exceed 15pF to maintain the specified maximum propagation delay of 4.0ns. Ensure the operating voltage remains within the 3.3V ±10% tolerance.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of 3.3V Fast CMOS logic circuits produced using advanced submicron technology. It is functionally equivalent to the legacy PI49FCT807 but optimized for 3.3V operation. The 'A' speed grade denotes specific timing characteristics distinct from B, C, or D grades available in the same family.

Clock Buffers, Drivers Replacement Considerations

PI49FCT3807BQEX offers similar functionality with potentially different speed grade characteristics. PI49FCT3807DQEX provides alternative timing parameters within the same QSOP package. Cross-reference speed grades carefully as propagation delays vary between A, B, C, and D designations.
