DDR SDRAM Terminator

TechnicalData Sheet

RoHS Compliant Parts Available

Description

Features

This SSTL_2 terminator network provides high performance

resistor termination for SSTL_2 Class I or Class II systems.

•

18 Bit SSTL_2 Termination Sets

Compliant to JEDEC Std. 8-9A

Excellent high frequency performance

Slim BGA Package

1% Resistor Tolerance

Low Channel Capacitance

Designed with a ceramic substrate, this device minimizes

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.

RoHS Compliant Designs Available

•

Compatible with both lead and lead-free

manufacturing processes

The BGA packaging has been proven to reduce rework and

improve reliability.
