PI49FCT3807DQ

Clock Buffers, Drivers Overview

The PI49FCT3807DQ is a 3.3V high-speed, low-noise, non-inverting 1-to-10 clock buffer manufactured by Diodes Incorporated. Designed for synchronous networking systems requiring tight skew levels, it supports input frequencies up to 156 MHz. The device features propagation delays of less than 2.5 ns and output-to-output skew under 250 ps. It operates with a supply voltage range of 3.0 V to 3.6 V and includes multiple VDD and GND pins to minimize noise. The component is housed in a 20-pin QSOP package.

Clock Buffers, Drivers Feature Summary

• Maximum operating frequency of 156 MHz
• Low-skew performance (<250ps) between any two output clocks
• Low duty cycle distortion (<250ps)
• Low propagation delay (<2.5ns)
• Multiple VDD and GND pins for noise reduction
• 3.3V supply voltage with 5V input tolerance

Clock Buffers, Drivers Applications

• Synchronous networking systems
• Clock distribution for high-frequency applications
• Networking equipment requiring low-jitter clock signals

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'EX' if tape-and-reel packaging is required, as the base model may be available in tubes. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer documentation before procurement. Ensure the QSOP package dimensions match the target PCB footprint requirements.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended, non-inverting clock signal requires expansion into ten distinct outputs with minimal timing skew. Verify that the system load capacitance does not exceed the specified limits to maintain the guaranteed propagation delay and rise/fall times. Consider the 5V input tolerance feature if interfacing with legacy TTL-compatible logic levels.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of Fast CMOS logic circuits produced using advanced submicron technology. It serves as a specialized clock driver within the broader portfolio of timing solutions offered by Diodes Incorporated (formerly Pericom Semiconductor). The device is engineered specifically for high-performance digital systems where precise clock synchronization is critical.

Clock Buffers, Drivers Replacement Considerations

Direct replacements must maintain the 1:10 fan-out ratio, 3.3V operation, and QSOP-20 package. Verify compatibility regarding propagation delay and skew specifications to ensure system timing integrity is preserved during substitution.
