Note 1:
Maximum ratings indicate limits beyond which permanent damage may occur. Continuous operation at these limits is not intended and should be limited
to those conditions specified under DC electrical characteristics.
Note 2:
The B
CLK
period decreases with increasing reference clock input. At higher clock input frequency, the number of B
CLK
increases.
