∗ This IC should be used mounted to a PC board.
If used mounted by a socket, the proper characteristics may not be able to be obtained.
•^{Attached components}
(1) Crystal oscillator
A crystal resonator with an oscillation frequency of 16.9344MHz is usually sufficient. However, if fO precision is
necessary, adjust by attaching a capacity to each end of the crystal oscillator.
(2) Power supply
VDD bypass capacitor
