Nah. A 127-bit pseudo-random shift register with resistive summing into a
low-pass gaussian or bessel filter.

Some of the advantages are: easy to calibrate, close enough to random so
you can't tell the difference, initialize to any preset state, repeatable
every time for production testing, pretty good bandwidth, no drift,
inexpensive, can easily be duplicated with identical performance.
