stray capacitance of the board to match the nominally
required crystal load capacitance. Because load
capacitance can only be increased in this trimming process,
it is important to keep stray capacitance to a minimum by
using very short PCB traces (and no vias) between the
crystal and device. Crystal capacitors, if needed, must be
connected from each of the pins X1 and X2 to ground.
The value (in pF) of these crystal caps should equal (CL -16
pF)*2. In this equation, CL= crystal load capacitance in pF.
Example: For a crystal with an 18 pF load capacitance, each
crystal capacitor would be 4 pF [(18-16) x 2] = 4.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the MK2703B. These ratings, which are
standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at
these or any other conditions above those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical
parameters are guaranteed only over the recommended operating temperature range.
