∗ 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
