(1) Connect pin 1 to GND via a 120k
(approx.) resistor. Leave pins 2, 4 and 8 open.
(2) SYNC output polarity (pin 3) is positive.
(3) The delay time for rising edge of the SYNC output (pin 3) with respect to the falling edge of Sync for the Vsig
input signal (pin 6) is 850ns (reference value).
(4) The delay time for falling edge of the SYNC output (pin 3) with respect to the rising edge of Sync for the Vsig
input signal (pin 6) is 450ns (reference value).

By configuring the circuit enclosed in the dotted line to that in the
diagram on the right, you can decrease the lock-in time and increase the
capture range.
