PI6C182AHE

Clock Buffers, Drivers Overview

The PI6C182AHE is a high-speed, low-noise, non-inverting 1-to-10 clock buffer designed for SDRAM applications. It supports frequencies up to 125 MHz with propagation delays of 5.5 ns maximum and output skew under 200 ps. The device operates on a single 3.3V supply within a 28-pin SSOP package. It features an I2C serial interface for individual output enable/disable control and includes a dedicated OE pin for global tri-stating.

Clock Buffers, Drivers Feature Summary

• 1-to-10 non-inverting buffer supporting up to 125 MHz
• I2C serial configuration for individual output control
• Low skew (<200ps) between any two output clocks
• Multiple VDD/VSS pins for noise reduction

Clock Buffers, Drivers Applications

• SDRAM clock distribution
• Supporting up to four SDRAM DIMMs

Clock Buffers, Drivers Procurement Notes

Verify the component origin as Pericom Semiconductor, now part of Diodes Incorporated. Confirm the specific ordering suffix 'HE' corresponds to the 28-pin SSOP Pb-free & Green package variant. Ensure compatibility with the specified 3.3V operating voltage and ambient temperature range of 0°C to 70°C.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:10 fan-out is required for SDRAM clock networks. The PI6C182A variant is necessary for designs requiring operation up to 125 MHz, whereas the standard PI6C182 supports up to 110 MHz. Consider the I2C interface requirements for dynamic output management.

Clock Buffers, Drivers Part Context

This component belongs to the PI6C182 family of precision clock buffers. The 'A' suffix denotes the higher frequency capability (125 MHz). The 'H' indicates the 28-pin SSOP package, and 'E' signifies Pb-free and green manufacturing compliance.
