PI49FCT3807BQEX

Clock Buffers, Drivers Overview

The PI49FCT3807BQEX is a 3.3V Fast CMOS clock driver manufactured by Diodes Incorporated, featuring one input and ten outputs for 1:10 fanout distribution. It operates within a supply voltage range of 3V 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 3.8ns max at VCC = 3.3V with CL = 15pF. It utilizes TTL-compatible inputs and CMOS outputs, housed in a 20-pin QSOP package.

Clock Buffers, Drivers Feature Summary

• 1-to-10 clock fanout with ultra-low skew (0.35ns typ) and high-speed propagation delay (max 3.8ns).
• TTL input and CMOS output compatibility with VOH = 3.3V (typ) and VOL = 0.3V (typ).
• Low input capacitance (max 6.0pF) and minimum duty cycle distortion.
• Industrial temperature operation from –40°C to +85°C.

Clock Buffers, Drivers Applications

• Clock and signal distribution systems.
• High-speed digital circuit timing networks.
• Load reduction on primary clock sources.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'Q' corresponds to the 20-pin 150-mil wide QSOP package and 'E' indicates Pb-free/Green status. Confirm the speed grade 'B' aligns with required propagation delay specifications. Ensure the 'X' suffix matches tape/reel packaging requirements if applicable.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source requires distribution to ten loads with minimal skew. Verify that the 3.3V supply voltage and TTL input levels match the system design. Consider the 20-pin QSOP footprint constraints during PCB layout.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT3807 series, which includes variants with different speed grades (A, B, C, D) and packages (SSOP, QSOP, SOIC). The 'B' grade specifies specific propagation delay limits compared to other speed grades in the family.
