Description
The DS1123L is an 8-bit programmable timing element similar in function to the DS1023, but operating at 3.3V. Like the DS1023, the DS1123L can delay signals up to a full period or more when used as a delay line, and an on-chip reference delay can be used to offset the inherent "step-zero" delay. This allows the DS1123L to shift a clock signal over the full 0 to 360° phase range. In addition to functioning as a delay line, it can be configured as a free-running oscillator or an externally triggered monostable vibrator.

Key Features   Applications/Uses
  • Step Sizes of 0.25ns, 0.5ns, 1ns, 2ns
  • On-Chip Reference Delay
  • Configurable as a Delay Line, Monostable Vibrator, or Free-Running Oscillator
  • Can Delay Signals by a Full Period or More
  • Guaranteed Monotonicity
  • Parallel and 3-Wire Serial Programming Interface
  • Single 3.3V Power Supply
  • 16-pin TSSOP
