I do not know for certain that the TS117 will not work, SSRs differ from standard relays in one critical way, SSRs rely on transistors to perform the switching operation, because of this you will have the same draw backs and limitations of using them including a natural low pass filter who's corner frequency is determined by the capacitance of the transistors (Cgs and Cgd on a Mosfet, or the capacitance of the base-emitter junction diode of a BJT). This capacitance affects how quickly the circuit can be charged and discharged, effecting the maximum frequency. Standard relays dont suffer from this problem to the same degree but you waste a lot of current activating a standard relay. There should be SSRs designed for higher speeds but I doubt a SSR designed for 56kHz data rate (even 10x oversample is only 560kHz) will be able to handle a 50MHz signal. I will take a look later to see if I can find one which definately supports 50Mhz signal.
