DDR SDRAM Terminator

Technical Data

• Compliant to JEDEC Std. 8-9A

•SlimBGAPackage

Description

• 1% Resistor Tolerance

• Low Channel Capacitance

Features

• Excellent High Frequency Performance

• 18 Bit SSTL_2 Termination Sets

This SSTL_2 termination network provides high

performance resistor termination for SSTL_2 Class I

or Class II systems.

Designed with a ceramic substrate, this device

virtually eliminates channel capacitance, a primary

cause of reduced system performance. In addition,

the BGA package eases routing design, saving the

designer many hours of printed circuit layout.

The BGA packaging has been proven to reduce

rework and improve reliability.
