Input setting : Set pin 11 to 0 V, and apply pulse
signal whose High period is 4 s
and amplitude is 5 V (increase from
0 V to 5 V) to pin 14. Change input
frequency.
Test content : Change input frequency with fh
(15.734 kHz) as reference and
measure pull-in range where HD
frequency of pin 17 locks to the input
frequency.

period of input pulse.
Test content : Increase input pulse width from
50 ns and measure input pulse width
where HD frequency of pin 17 locks
to fh.
