Rev. 2.10
Internal CIS Reference Circuit (DB 4 = 1)
The XRD9824 has an internal register reserved for
interfacing to the Canon CIS model number CVA-
60216K. When this register is selected, the VDCEXT
(Pin 16) becomes an output voltage of 1.24 volts. This
voltage can be directly connected to the VREF (Pin 15)
of the Canon sensor. This reduces the amount of
Figure 10. Typical Application Circuitry Internal CIS Reference Circuit Mode
CANON CIS Sensor, Model #CVA=60216k
components needed for biasing the Canon CIS sensor
(the external diodes and resistors typically used in this
application have been included inside the XRD9824 for
this mode of operation). Below is a typical application
circuit using the XRD9824 and the Canon CVA-
60216K CIS sensor.
