This document describes the features and characteristics of a product named PS8141D. The product is a high-speed low-noise non-inverting 1-18 buffer designed for SDRAM clock buffer applications. It supports up to four SDRAM DIMMs and has low skew (< 250ps) between any two output clocks. The product features an I2C Serial Configuration interface, multiple VDD and VSS pins for noise reduction, and operates at a 3.3V power supply voltage. It also has a separate Hi-Z pin for testing. The product is available in a 48-pin SSOP package.
The Pericom PI6C180 is a precision 1-18 noninverting buffer designed specifically for SDRAM clock buffer applications. It supports frequencies up to 125 MHz (for the PI6C180A variant) and features low skew between output clocks, making it suitable for high-performance memory systems.
