NOTES :
1. Start signal :
Cycle t
SP = 63.5 µs, "H" period width tWSP = 80 ns.
CTR signal :
Cycle t
CTR = 127.0 µs, "H" period width tWCTR = 63.5 µs.
Change from "H" to "L" or "L" to "H" is synchronized with
start pulse during blanking period.
CK signal :
Frequency f
CK = 12.5 MHz (duty = 50%)
V
A = VB = VC = 0.1 V to VCCA – 0.1 V
Connect all other pins to high level.
Voltage difference between the average voltage of all
OS output pins in the chip and the output voltage of
each OS output pin. T
A = 25 °C
