FEATURES AND BENEFITS

The DDR110 provides 10 bits resistor Network to

be used for SDR/DDR (double data rate) SDRAM

bus Termination.

This device has a series resistors (Rs) to reduce

signal reflection noise. This eliminates the need for

external terminating resistors.

The DDR Termination Nerwork is enabled with the

output Enable pin (OE). When OE is HIGH Inputs

are connected to Outputs (A connected to B).

When OE is LOW every inputs are in High

impedance state (Hi - Z).

The DDR Termination Network is a bidirectional

device when the internal switch is ON. When the

switch is OFF, the device will block current in both

directions.

This device is made using ST IPAD

TM (Integrated

Passive & Active devices) technology.
