PI49FCT3807DSE

Clock Buffers, Drivers Overview

The PI49FCT3807DSE is a 3.3V high-speed, low-noise 1-to-10 non-inverting clock buffer manufactured by Diodes Incorporated (formerly Pericom). Designed for networking applications requiring low-skew and low-jitter clock distribution, it supports input frequencies up to 156 MHz. The device operates with a supply voltage of 3.3V ± 0.3V and features 5V input tolerance. It is housed in a 20-pin SOIC package with a 300-mil width. Key electrical characteristics include propagation delays under 2.5 ns at 85°C and output-to-output skew as low as 250 ps.

Clock Buffers, Drivers Feature Summary

• Maximum operating frequency of 156 MHz
• Low skew (<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 tolerant

Clock Buffers, Drivers Applications

• Networking applications requiring tight skew levels
• Synchronous systems with large numbers of outputs
• Clock distribution for high-frequency digital circuits

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'E' indicates Pb-free and Green packaging status as specified in the datasheet. Confirm the package code 'S' corresponds to the 20-pin 300-mil wide SOIC form factor. Ensure compatibility with industrial temperature ranges (-40°C to +105°C) if required for the specific application environment.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:10 fan-out buffer is needed with strict skew requirements below 250ps. It is suitable for 3.3V logic systems interfacing with 5V inputs. Consider the SOIC package dimensions for PCB layout constraints. Verify that the load capacitance does not exceed typical test conditions (15pF) to maintain specified timing parameters.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT3807 series of clock buffers. Other variants include the DHEX (SSOP), DQEX (QSOP), and DS (standard SOIC). The 'E' suffix specifically denotes environmental compliance (Pb-free & Green). The manufacturer transitioned from Pericom Semiconductor Corporation to Diodes Incorporated.
