PIN NO. SYMBOL IO SYMBOL POLARITY
DESCRIPTION
30 WB1
IO4MD
WB setting. Use together with WB1 and WB2
00 (WB2, WB1) : Auto white balance 01 : WB1 mode 10 : WB2 mode
11 : WB3 mode
31 WB2
IO4MD
These pins are 0 bit (WB1) and 1st-bit (WB2) of UV output in output digital YUV
mode.
Setting for mirroring video output mode
32 MIR
IO4MD
L : Normal H : Mirroring
This pin is 2nd-bit of UV output in output digital YUV mode.
33 BLC
IO4MD
Switching internal register for exposure-standard
This pin is 3rd-bit of UV output in digital output mode.
34 GNDDA
–
Ground for internal D/A converter
35 VDDDA
–
Power supply for internal D/A converter
Connect to DC 3.3 V power supply (+3.3 V).
36 VB
DAO
DC output of internal D/A converter. Connect to ground pin via capacitor.
37 IREF
DAO
DC output of internal D/A converter. Connect to ground pin via register.
38 VREF
DAI
DC reference input for internal D/A converter
Connect to DC power supply (+1.0 V).
39 GNDDA
–
Ground for internal D/A converter.
40 VIDEO DAO
Analog video output
41 EEMDS IO4MU
Switching electronic shutter control
Use together with EEMDS, EEMD1, EEMD2 and EEMD3. Refer to "Electronic
42 EEMD1 IO4MU
Shutter Speed Setting" in AUTOMATIC CAMERA FUNCTION CONTROL.
These pins are 4th to 7th-bit of UV output in digital output mode.
43 EEMD2 IO4MU
When in line lock mode,
44 EEMD3 IO4MU
EEMD2 : H reset
EEMD3 : V reset
45 GND
–
Ground
46 VDD
–
Power supply input (+3.3 V).
47 DCK1 OBF4M
Clock output synchronized with digital output
Switchable among CSYNC, CBLK or L level.
ID pulse output of UV signal for digital output
When in analog output, output is KEI or L level.
48 DCK2 OBF4M
KEI pulse : At power-on, begin with L level. When shutter speed is 1/60 s (PAL
1/50 s) and PGA gain is more than the value in address 92h, it goes to H level
and becomes stable.
