Key Features

  • 1.8 ± 0.1 V power supply and HSTL I/O
  • DLL circuitry for wide output data valid window and future frequency scaling
  • Pipelined double data rate operation
  • Four-tick burst for reduced address frequency
  • 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 with µs restart
  • User programmable impedance output
  • Fast clock cycle time : 3.3 ns (300 MHz), 4.0 ns (250 MHz), 5.0 ns (200 MHz)
