 INMs are suitable for both board level implementation, and ASIC implementation.  Speed is
 limited by the speed of a voltage buffer and comparator, and can run in excess of 100
 Mbit/second per second with high performance components.  Cheap solutions with CMOS quad
-op-amps can run at 500 Kbit/second.
+op-amps can run at 6Mbit/second.
 
 Adjacent bits from an INM are correlated, so whitening is required before use in
 cryptography.  INM output has a highly predictable amount of entropy for easy estimation
