The glass used does not expand easily with rising temperatures, so the temperature dependency of the wavelength is extremely small. | The metal package provides high humidity resistance. Low cost is achieved because it is a hollow type. | Being ultra-compact, it can be integrated into mobile devices and drones. |

Start pulse period [tpi(ST)] |
= Video data rate
= 5 MHz
|
Minimum low start pulse period [tlp(ST)] |
= 343/f(CLK)
= 343/5 MHz
= 68.6 μs
|
High start pulse period [thp(ST)] |
= Start pulse period [tpi(ST)] - Minimum low start pulse period [tlp(ST)]
= 69.8 μs - 68.6 μs
=1.2 μs
|
Because the integration time is equivalent to high start pulse period + the period of 48 clock pulses, we obtaine 1.2 μs + 9.6 μs = 10.8 μs.
