91 | * The devices have an upper samplerate limit of 100/200/500 MHz each. |
92 | * But their hardware uses different base clocks (100/200/800MHz, this | |
93 | * is _not_ a typo) and a 16bit divider. Which results in per-model ranges | |
94 | * of supported rates which not only differ in the upper boundary, but | |
95 | * also at the lower boundary. It's assumed that the 10kHz rate is not | |
96 | * useful enough to provide by all means. Starting at 20kHz for all models | |
97 | * simplfies the implementation of the config API routines, and eliminates | |
98 | * redundancy in these samplerates tables. | |

100 | * Streaming mode is constrained by the channel count and samplerate |
101 | * product (the bits per second which need to travel the USB connection | |
102 | * while the acquisition is executing). Because streaming mode does not | |
103 | * compress the capture data, a later implementation may desire a finer | |
104 | * resolution. For now let's just stick with the 1/2/5 steps. | |
