Description
40, 46, 51
AVDD
Analog Supply Voltage
Supplies the 5V power to the analog section of the CH5001.
41
Out
VREF
Voltage Reference
VREF provides a 1.235V reference. A 0.01
μ
F decoupling capacitor
should be connected between VREF and AGND.
37, 43, 48
Power
AGND
Analog Ground
These pins provide the ground reference for the analog section of
CH5001. Pins
must
be connected to the system ground to prevent
latchup.
42
Out
CRF
Column Filter
CRF provides a 2.5 V reference. A
0.1
μ
F decoupling capacitor should
be connected between CRF and AGND.
49, 50
In/Out
TOUT, TOUTB
Test Mode I/O Pins
For test purposes only. Should be NC.
44, 45
Out
ARF2, ARF
Array Filters
A 0.1uF decoupling capacitors should be connected between each of
the pins and AGND.
47
Out
Array Bias Filter
VRS provides a 2.1V reference. A
0.1
μ
F decoupling capacitor should
be connected between VRS and AGND.

MONO
Monochrome (active high, internal pulldown)
Digital pin to select Color / Monochrome operation.
1= Monochrome 0=Color
35
In
PDP*
Power Down Pin (active low, internal pullup)
0 = power down
52
Out
CMB2
Bias Filter
A 0.1
μ
F decoupling capacitor should be connected between CMB2 and
AGND.
31-25
In
PUD[5:0]*
PUD[6]
Power Up Detect (internal pull-up)
These pins are shared with the C[6:0] chrominance output function. At
power-up they are inputs controlling the default value of IIC register bits
M0, ADDO, PD, ASW[3:0]. Attach 100K Ohms to DGND to pull low.
NOTE: PUD[5:0]* are logically inverted
