SMIC 0.13um DLL

Overview

The S13V33_DLL_04 generates 4-channel fixed timing delay. The operating voltage ranges from 1.08V ~ 1.32V, and the operating junction temperature from -40℃ ~ 125℃. It can process input clock frequency of 125MHz. This IP can generate a 45 degree (90, 135, 180, 225, 270, 315 degree optional) phase shift of DQS period that is represented by the reference input clock (CLK_DLL).

Key Features

  • 4-channel outputs with 45 degree (90, 135, 180, 225, 270, 315 degree optional) phase
  • shift of the period of CLK_DLL
  • Rise time matches fall time on the output signal’s edges
  • Lock in time: less than 10us
  • No need of independent power, can share the core power.
  • Delay accuracy as follows:
  • 1/8 T phase : 1ns +/- 0.5ns
  • 2/8 T phase : 2ns +/- 0.5ns
  • 3/8 T phase : 3ns +/- 0.5ns
  • 4/8 T phase : 4ns +/- 0.5ns
  • 5/8 T phase : 5ns +/- 0.5ns
  • 6/8 T phase : 6ns +/- 0.5ns
  • 7/8 T phase : 7ns +/- 0.5ns
