sg13g2-pll (2AMLogic)MCADConfidence: Medium

A consumer design re-graded the lock detector at 50 MHz and found LOCK active-low as netlisted, with no falling trip in 24 of 45 corners. The spec records the locked rail as low but "states no polarity contract." The recommended fix is to document polarity and keep the ratified 3.5 to 24.4 MHz range.
