Description
1 VSS1
— GND
2 RST
I
Internal system reset input.
Normally apply reset during power-on.
High: Normal operation, Low: Reset control
Schmitt trigger input
3
SNCSL
I
Control input used to switch sync system. High: CKI sync, Low: MCKO sync
With pull-down resistor
4
ID/EXP
O
Vertical direction line identification pulse output/exposure time identification pulse
output. Switching possible using the serial interface data. (Default: ID)
5 WEN
O Memory write timing pulse output.
6 SSGSL I ^{Internal SSG enable.}
High: Internal SSG valid, Low: External sync valid.
With pull-down resistor

— 3.3V power supply. (Power supply for common logic block)
8 VDD2
— 3.3V power supply. (Power supply for RG)
9 RG
O CCD reset gate pulse output.
10 VSS2
— GND
11 VSS3
— GND
12 H1
O CCD horizontal register clock output.
13 H2
O CCD horizontal register clock output.
14 VDD3
— 3.3 to 5.0V power supply. (Power supply for H1/H2)
15 VDD4
