- Note that the current design for the IF system
envisions a minimum bandwidth per baseband of 31.25 MHz; see
above.

- ...32.
- The clock
rate of the correlators is 125 MHz (see the discussion in Memo 166).
Since they cannot keep up with the 4 GHz rate of the samplers, we need 32
parallel correlators. When the sample rate goes to 2 GHz (1 GHz bandwidth),
we need only 16 parallel correlators; the extra 16 can then be used to generate
twice the number of lags. Obviously this recirculation is ultimately
limited by the number of parallel correlators. The full factor 32 that comes
from this can be gained by matching the sampler rate to the clock speed
(5#5 125 MHz 6#6 62.5 MHz bandwidth per baseband).
