PI49FCT3807BQE-1507

Clock Buffers, Drivers Overview

The PI49FCT3807BQE-1507 is a 3.3V Fast CMOS clock driver manufactured by Diodes Incorporated, originally designed by Pericom Semiconductor. It functions as a 1-to-10 fanout buffer with one input and ten outputs. The device supports TTL inputs and CMOS outputs, operating within a supply voltage range of 3.0V to 3.6V. Key electrical parameters include a maximum propagation delay of 3.8ns (Speed Grade B) and an ultra-low skew of 0.5ns between outputs. It operates across an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• 1:10 Fanout Configuration: Distributes a single clock signal to ten independent outputs.
• Ultra-Low Skew: Achieves output-to-output skew of 0.5ns and pulse skew of 0.35ns for Speed Grade B.
• TTL/CMOS Compatibility: Accepts TTL level inputs while providing CMOS compatible outputs.
• Low Power Consumption: Features quiescent current of 30µA typical at VCC = 3.3V.

Clock Buffers, Drivers Applications

• Clock distribution in synchronous digital systems.
• Signal distribution networks requiring low jitter and skew.
• High-speed data acquisition systems.
• Telecommunications equipment timing circuits.

Clock Buffers, Drivers Procurement Notes

Verify the specific speed grade suffix 'B' corresponds to the required propagation delay and skew specifications for your design. Confirm that the 'E' suffix indicates Pb-free and Green packaging compliance. Ensure the '-1507' suffix does not denote a custom or non-standard variant not covered in the standard datasheet ordering information.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:10 fanout is required with strict skew constraints. Speed Grade B offers a balance of performance with a max propagation delay of 3.8ns. Compare against Speed Grade C (3.5ns max delay) if higher speed is needed, or Grade A/D if different trade-offs are acceptable. Ensure the 20-pin SSOP package fits the PCB layout constraints.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT3807 family of 3.3V clock drivers. The base model PI49FCT3807 was originally developed by Pericom Semiconductor before being acquired by Diodes Incorporated. The 'H' package code denotes the 20-pin 209-mil wide SSOP form factor, while 'Q' would indicate QSOP and 'S' SOIC.

Clock Buffers, Drivers Replacement Considerations

Direct pin-compatible replacements from the same family include PI49FCT3807CHEX (Grade C, faster) or PI49FCT3807AHEX (Grade A). Cross-manufacturer equivalents like the 74FCT3807 series may require verification of voltage levels and pinouts.
