Note 1: Applicable to PD# input
Note 2: Applicable to SDATA and SCLK inputs
Note 3: Applicable to S3, S2, S1, S0, SIO, PD#, SDATA, and SCLK inputs. The pull-down resistor has a typical value
of 250KΩ, but may vary between 200KΩ to 500KΩ.
Note 4: This measurement is applicable with Spread Spectrum ON or OFF.
Note 5: Although the device will reliably interface with crystals of a 14pF – 20pF CL range, it is optimized to interface
with a typical CL = 16pF crystal specifications.
