The
analog functionality that directly effect power consump-
tion of the device. An external precision resistor pin is
available on the MCM20027 that may be used to more
accurately regulate the internal current sources. This
serves to minimize variations in power consumption that
are caused by variations in internal resistor values as
well as offer a method to reduce the power consumption
of the device. The default for this control uses the inter-
nally provided resistor which is nominally 12.5k . This
feature is enabled by setting the res bit of the
Configuration Register
the pin; EXTRES, and EXTRESRTN.
Power can be further reduced at lower clock rates.

Description
Description
The pbg bit of the
21, is used to enable/disable the “Programmable Bias
Generator”. When this bit is enabled, the user can vary
the power consumption of the White Balance PGA
(PGAWB), Exposure gain PGA A (PGAEXPa), Expo-
sure gain PGA B (PGEXPb), Frame Rate Clamp (FRC),
Column Offset DOVA (COL_DOVA), Global offset
DOVA (DOVE) and/or the Analog to Digital converter
(A2D) between half an full current (power) consumption.

When this bit is disabled, it will use the power config-
ured by the internal or external resistor (bit 3).
