Video Output
Provides the luminance data of the digital video output.
Digital Supply Voltage
These pins supply the 5V power to the digital section of CH5001.
Digital Ground
pins MUST be connected to the system ground.
Video Output
Chrominance data of the digital video output are provided by these
pins.
Cr Select
CRS specifies the CrCb data sequence. CRS is an alternating signal.
CRS=1 indicates that C[7:0] carry the Cr data. CRS=0 indicates C[7:0]
carry the Cb data.
Video Pixel Clock Output
This pin outputs a buffered clock signal which can be used to latch data
output by pins Y[7:0] and C[7:0].
Vertical Sync Output (active low)
Outputs a vertical sync pulse.
Horizontal Sync Output (active low)
Outputs a horizontal sync pulse.
Over Range
This pin is high when the A/D converter input is beyond the full scale
range of the A/D.
Horizontal Reference
Active video timing signal. This output is high when active data is being
output from the device, and low otherwise.
Serial Clock
IIC clock input pin.
Serial Data
IIC data input/output pin.
Chip Address Select (internal pullup)
This pin selects the IIC address for the device.
AS = 1 Address = 100 0101
AS = 0 Address = 100 0110
Chip Reset (active low, internal pullup)
Puts all registers into power-on default states. The state at pin SD must
be HIGH during reset for proper initialization.
Crystal Output
A 27 MHz (± 50 ppm, parallel resonance) crystal may be attached
between XO and XI/FIN.
Crystal Input or External input
A 27 MHz (± 50 ppm, parallel resonance) crystal should be attached
between XO and XI/FIN. An external CMOS compatible clock can be
connected to XI/FIN as an alternative.
Provides the ground reference for the digital section of CH5001. These
