NOTES:

1.0: Requires external regulation

`

2.0: From a 20 ppm offset in reference frequency

3.0: Offset between Reference Input and Reference Output @ room temp.

4.0: Offset change between Reference Input and Reference Output over temperature range from room temperature.

5.0: The SCG2015 will maintain an offset/skew, between the reference input and the oscillator output, of X ± 1ns. X is TBD.
