Applicable to S(0:3).
Applicable to Sdata, and Sclk.
Although internal pull-down resistors have a typical value of 250K, this value may vary between 200K and 500K.
All outputs loaded as per table 5 below.
Although the device will reliably interface with crystals of a 15pF – 20pF CL range, it is optimized to interface with a typical CL = 16pF
