Description
30
LST
OD
Line start. Active high pulse (start of active video lines).
32
PV
OD
Pixel sample clock. Qualifies video output for external image capture.
33
PVB
OD
Pixel sample clock bar. Inverse of PV.
35
CPE
ID↓
Pixel sample clock enable. Default CPE = 0 i.e. PV/PVB disabled.
36
FST
OD
Field start. Synchronises external image capture.
37
ODD
OD
Odd/even field signal. (ODD = 1 for odd fields, ODD = 0 for even)
DIGITAL CONTROL SIGNALS
16
SAB1
ID↓
Higher bit of two least significant bits of device address on serial interface.
17
SIN
ID↓
Used to reset video timing control logic without resetting any other part of
VV5430. Resets video logic on the falling edge of the SIN pulse.
18
SCE
ID↓
Scan mode enable - only relevant to test mode.
19
LIN
ID↓
Gamma corrected or Linear output. LIN = 0, gamma corrected output,
LIN = 1, linear output. Default is gamma. LIN = 0 can be overridden via serial
interface.
20
SAB0
ID↓
Lower bit of two least significant bits of device address on serial interface.
21
AEC
ID↑ Automatic exposure control. AEC = 1, auto exposure is enabled; AEC = 0 auto
exposure and auto gain control are disabled. AEC = 1 can be overridden via
serial interface.
22
AGC
ID↑
Automatic gain control enable. AGC = 1, auto-gain is enabled (if AEC = 1);
AGC = 0, auto-gain is disabled. AGC can be overridden via serial interface.
23
CCIR
ID↑ Select default video mode for power-on. CCIR = 1 for CCIR video. EIA video
mode is selected when CCIR = 0. Default is CCIR if unconnected
28
BKLIT
ID↓ Normal or Backlit exposure control mode. BKLIT = 0, normal mode. BKLIT = 1,
backlit mode. Default is normal. BKLIT state can be overridden via serial inter-
face. See Exposure Control for details.
29
RESETB
ID↑
Active low camera reset. All camera systems are reset to power-on state.
38
SCI
ID↓
Scan chain input - only relevant to test mode.
39
SCL
ID↑
Serial bus clock (input only). Must be generated by comms. host.
40
SDA
BI↑
Serial bus data (bidirectional, open drain).
Key:
OA- Analogue output
OD- Digital output
OD↓-Digital output with internal pull-down
BI - Bidirectional
IA - Analogue input
ID - Digital input
ID↑ - Digital input with internal pull-up
