Signal Path
The MT9V022 signal path consists of a programmable gain, a programmable analog
offset, and a 10-bit ADC. See “Black Level Calibration” on page 30 for the programmable
offset operation description.
The ADC voltage reference is programmed through R0x2C, bits 2:0. The ADC reference
ranges from 1.0V to 2.1V. The default value is 1.4V. The increment size of the voltage
reference is 0.1V from 1.0V to 1.6V (R0x2C[2:0] values 0 to 6). At R0x2C[2:0] = 7, the refer-
ence voltage jumps to 2.1V.
The effect of the ADC calibration does not scale with V
tive to the output of the analog gain stage. At default, one LSB of calibration equals two
LSB in output data (1LSB
It is very important to preserve the correct values of the other bits in R0x2C. The default
register setting is 0x0004.
This voltage is used for pixel high dynamic range operations, programmable from R0x31
through R0x34.
Chip version registers R0x00 and R0xFF are read-only.
