The individual circuit performance can be found in the Typical Performance Characteristics that curve graphs illustrate how the maximum output current is affected by changes in AVIN and PVIN. STUB-SERIES TERMINATED LOGIC(SSTL) TERMINATION SCHEME SSTL was created to improve signal integrity of the data transmission across the memory bus. This termination scheme is essential to prevent data error from signal reflections while transmitting at high frequencies encountered with DDR-SDRAM. Class II single parallel termination(SSTL-2) is the most popular termination form. It involves one RS series resistor from the chipset to the memory and one RT termination resistor (refer to Figure 1). RS and RT are changeable to meet the current requirement from UR5596, the recommended values both RS and RT are 25Ω. Figure 1. SSTL-Termination Scheme FOR SSTL-2 APPLICATIONS For the majority of applications that implement the SSTL- 2 termination scheme, it is recommended to connect all the input rails to the 2.5V rail as Figure 2. This provides an optimal trade-off between power dissipation and component count and selection. + + + VTT VDDQ VSENSE VREF GND SHDN AVIN PVIN CIN SHDN VDDQ=2.5V VDD=2.5V COUT CREF VREF=1.25V VTT=1.25V UTC UR5596 Figure 2.
