Features

? 1.8 ± 0.1 V power supply

? 165-pin PLASTIC BGA (13 x 15)

? HSTL interface

? PLL circuitry for wide output data valid window and future frequency scaling

? Separate independent read and write data ports with concurrent transactions

? 100 bus utilization DDR READ and WRITE operation

? Two-tick burst for low DDR transaction size

? Two input clocks (K and K#) for precise DDR timing at clock rising edges only

? Two output clocks (C and C#) for precise flight time and clock skew matching-clock
