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

and data delivered together to receiving device

• Internally self-timed write control

• Clock-stop capability. Normal operation is restored in 20 μs after clock is resumed.

• User programmable impedance output (35 to 70 Ω)

• Fast clock cycle time : 3.3 ns (300 MHz), 2.0 ns (250 MHz)

• Simple control logic for easy depth expansion

• JTAG 1149.1 compatible test access port
