2.6 Snubber

Resistors R1 and R25 and capacitors C4 and C32 act as a snubber, and can be tweaked to control the overshoot and settling behavior of the output laser current waveform. By default, R1 and R25 are 5Ω, and C4 and C32 are 300pF. The snubber can be removed to get the fastest rise-and-fall time, but removal can cause overshoot and undershoot in the current waveform. See the device data sheet for the recommended RC value for the snubber.
