PI6CV304LE

Clock Buffers, Drivers Overview

The PI6CV304LE is a low-skew, low-noise, high-speed clock buffer manufactured by Diodes Incorporated. It operates at frequencies up to 160 MHz with a maximum propagation delay of 3 ns and output skew of 150 ps. The device features four LVCMOS outputs driven by a single CMOS/TTL input, powered by a 3.3 V supply (3.0 V to 3.6 V). It includes an active-low Output Enable (OE) pin that tristates all outputs to reduce EMI and power consumption. The component is housed in an 8-pin TSSOP package and supports an industrial operating temperature range from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Supports 160 MHz operation with 2.0 ns typical propagation delay
• Low noise and low skew performance with 150 ps maximum output skew
• Features 5V I/O tolerant input and 3.3V power supply
• Includes OE pin for tristate control to minimize EMI and power usage

Clock Buffers, Drivers Applications

• PCI(X) clock buffers in servers and workstations
• PCI(X) Storage Area Network (SAN) and RAID controllers
• 80 MHz clocks for 10/100 Mbps Ethernet
• 125 MHz clocks for Gigabit networking
• 155 MHz clocks for Optical OC3/SDH/SONET

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'L' corresponds to the 8-pin 173-mil wide TSSOP package. Confirm RoHS compliance status as the datasheet indicates Pb-free and Green packaging availability for this variant. Ensure the design accommodates the 3.3V supply voltage range and industrial temperature specifications.

Clock Buffers, Drivers Selection Notes

Select the PI6CV304LE over the PI6CV2304LE when a lower output impedance of 20 ohms is required, compared to the 30-ohm impedance of the PI6CV2304LE. Both devices share similar electrical characteristics but differ in drive strength. Verify that the application requires 160 MHz capability rather than the 140 MHz limit of the PI6CV2304 series.

Clock Buffers, Drivers Part Context

This component belongs to the PI6CV304/PI6CV2304 family of 160 MHz clock buffers originally developed by Pericom Semiconductor Corporation, now part of Diodes Incorporated. The family provides low-skew distribution solutions for computing and communication systems. The PI6CV304LE specifically denotes the lead-free and green packaging version in the TSSOP format.

Clock Buffers, Drivers Replacement Considerations

The PI6CV2304LE serves as a functional substitute within the same family, differing primarily in output impedance (30 ohms vs. 20 ohms) and maximum frequency (140 MHz vs. 160 MHz). Other generic clock buffers may require verification of skew, drive strength, and voltage compatibility.
