Overview
|
||
|
|
--------
|
||
|
|
The T4240QDS is a high-performance computing evaluation, development and test
|
||
|
|
platform supporting the T4240 QorIQ™ Power Architecture™ processor. T4240QDS is
|
||
|
|
optimized to support the high-bandwidth DDR3 memory ports, as well as the
|
||
|
|
highly-configurable SerDes ports. The system is lead-free and RoHS-compliant.
|
||
|
|
|
||
|
|
