WebDDR. CBTU02044 offers numerous benefits, such as a wide VDD range (1.62 V to 3.63 V), low insertion loss, low crosstalk, low return loss, and a 17GHz typical -3dB bandwidth. CBTU02044 is a small package with optimized footprint for smaller real estate occupancy. This document provides PCB design guidelines and considerations while using CBTU02044. WebTable 11 in section 4.3.1.4 in SPRABI1B lists the maximum stub length for the address / command lines to be < 80 mils. When designing with fly-by topology with two DDR3 chips running at 666 MHz, can the stub length be longer, ideally up to 300 mil? 80 mil seems impossible with this topology and the termination resistors. Thanks, DJ WebSSTL is primarily designed for driving the DDR (double-data-rate) SDRAM modules used in computer memory; however, it is also used in other applications, notably some PCI Express PHYs and other high-speed devices.
