Key Features

  • 450-MHz clock for high bandwidth
  • 2-word burst for reducing address bus frequency
  • Double data rate (DDR) interfaces (data transferred at 900 MHz) at 450 MHz
  • Available in 2.0 clock cycle latency
  • Two input clocks (K and K) for precise DDR timing ❐ SRAM uses rising edges only
  • Echo clocks (CQ and CQ) simplify data capture in high-speed systems
  • Data valid pin (QVLD) to indicate valid data on the output
  • Synchronous internally self-timed writes
  • DDR II+ operates with 2.0 cycle read latency when DOFF is asserted HIGH
  • Operates similar to DDR I device with 1 cycle read latency when DOFF is asserted LOW
