I just want to remind you, SRS10 is quite old atomic clock, just for your play use, I keep a new for the reference, if you want the accurate timing reference, just use the SRO, and the audio fans also can use the 0-20MHz frequency.

the SRO clock can generate 0-20MHz square wave, the frequency defined by customer, especially used in Digital Audio System, just now, I checked RME Fireface 800 device, it needs: 32KHz 44.1KHz 48KHz 88.2KHz  96KHz  176.4KHz  192KHz  11.2896MHz , the SRO clock all supports.
