Direction Description
Output
Loop Filter. A series RC low-pass filter must be
tied between this pin and analog ground
V_SS(A). There must also be second capacitor
from the pin to V_SS(A).

Input
Reference setting resistor. This resistor must
be 10 kOhms, ±2%.
N/A
This pin is the lowest potential power pin for
the analog circuit that is typically tied to
system ground.
N/A
The voltage on this pin is nominally 5.0 Volts,
and may range between 4.75 to 5.25 Volts with
respect to the V_SS pins.
Output
This pin is HIGH(1) when the received Content
Advisory packet matches the viewers
selection as entered into the Content Advisory
Rating Select registers.
In/Output This pin is the bidirectional data line for
sending and receiving serial data.
Input
This pin acts as an input pin for the serial clock
signal from the I²C master. The clock rate is
expected to be within I²C limits.
N/A
No Connect
Output
This pin provides an interrupt signal to the
master control device in accordance with the
settings in the Interrupt Mask Register.
