DIGITAL CONTROL SIGNALS

16

SAB1

ID↓ Chip Address, Bit 1

17

SIN

ID↓ Used to reset video timing control logic without resetting any other part of

VV5402. 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.

20

SAB0

ID↓ Chip Address, Bit 0

21

AEC

ID↑ Automatic exposure control. AEC = 1, auto exposure is enabled; AEC = 0

auto exposure and auto gain control are disabled.

22

AGC

ID↑ Automatic gain control enable. AGC = 1, auto-gain is enabled (if AEC = 1);

AGC = 0, auto-gain is disabled.

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. 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.
