It sets the output sampling rate of the USRP, and hence the usable bandwidth. Internally, it sets the DDC chain's decimation, so if you request 1 Msps, it will decimate from 100 MHz sampling rate by a factor of 100.
The rate at which the IF is sampled from the TVRX2 is, as you point out, fixed to 100 MHz on the N200.
