Pin Type
Sensing Power (+5V) pins.
Analog Power (+5V) pins.
Digital Power (+5V) pins.
Digital I/O Power (+5V / +3.3V) pins.
Sensing ground connections. Connect to supply common
Analog ground connections. Connect to supply common
Digital ground connection. Connect to supply common
Digital Output ground connection.
Chip reset, “high” active.
AGCEN =1 enables the Auto Gain Control. AGCEN = 0 disables it. This pin
setting is effective when pin SBB = 1.
RAMINT=1 initializes frame transfer.
Frame exposure control input, effective in progressive scan only. The positive
width of FREX defines the exposure time.
Internal voltage reference. Requires an 0.1uF decoupling capacitor to ground.
PWDN =1 puts chip in power down (sleep) mode.
Internal voltage reference. Requires an 0.1uF decoupling capacitor to ground.
Internal voltage reference. Requires an 1.0uF decoupling capacitor to ground.
SBB = 1 selects the power-up method of programming the internal functions.
SBB = 0 selects the SCCB pin programming method. Results of the power-up
method can only be changed by a new power-up or reset sequence.
Video Test Output (NTSC)
VSYNC: Vertical sync output. This pin is asserted high during several scan
lines in the vertical sync period.
CSYS: Composite Sync. When not using SCCB, a 10k pull up changes pin
42(CHSYNC) to CSYS.
FODD: Odd field flag. Asserted high during the odd field, low during the even
field.
SRAM: External SRAM
HREF: Horizontal window reference output. HREF is high during the active
pixel window, otherwise low.
VSFRAM: Vertical Sync Frame.
UV7: Digital output UV bus. UV7 used for 16-bit operation for outputting
chrominance data.
B8: Switch for 8-bit mode luminance/Chroma tristate. Default is 16-bit mode.
UV6: Digital output UV bus. UV6 used for 16-bit operation for outputting
chrominance data.
BPCLR: Bypass RGB color matrix.
UV5: Digital output UV bus. UV5 used for 16-bit operation for outputting
chrominance data.
MIR: Mirror.
UV4: Digital output UV bus. UV4 used for 16-bit operation for outputting
chrominance data.
SLAEN: Slave Enable.
UV3: Digital output UV bus. UV3 used for 16-bit operation for outputting
chrominance data.
ECKLO: Swap clock output - changes pin 17(FODD) to XCLK out.
