Block Diagram
Available in two options: QDR-IV HP (RTR 1,334 MT/s) and
QDR-IV XP (RTR 2,132 MT/s)
Two independent, bidirectional DDR1 data ports
Error-correcting code (ECC) to reduce soft error rate to less
than 0.01 Failure-in-Time (FIT) per megabit
Bus inversion to reduce simultaneous switching I/O noise
On-die termination (ODT) to reduce board complexity
De-skew training to improve signal-capture timing
I/O levels: 1.2-1.25 V (HSTL/SSTL), 1.1-1.2 V (POD2)
Package: 361-pin FCBGA3
