Overview

J-Link Signal Smoothing Adapter

The Signal Smoothing Adapter can be inserted between the J-Link debug probe or Flasher in-cicruit programmer and the debug target to overcome signal integrity issues. Depending on target load capacitance JTAG signals might be affected by overshoot and ringing. In this case user adjustable series resistors (default 47R) allow for damping critical signal rise/fall times leading to improved signal integrity.
