DSDA0

I/O

DDC I2C Data for respective port. 
These signals are true open drain, and do not pull-down to ground when power is not applied to the device.  
These pins require an external pull-up resistor.

R0PWR5V

 -

5-V Port detection input for respective port. 
Connect to 5-V signal from HDMI input connector.
These signals require a 10

Ω series resistor and at least a 1µ F capacitor to ground A 3.3kΩ pull-down resis-

tor is also required for these signals.

CSCL

I

Local Configuration/Status I2C Clock. 
Chip configuration/status is accessed via this I2C port. This pin is a true open drain, so it does not pull to 
ground if power is not applied. 

53

CSDA

I/O

Local Configuration/Status I2C Data. 
Chip configuration/status is accessed via this I2C port. This pin is a true open drain, so it does not pull to 
ground if power is not applied.

48

DSCL4

I

DDC I2C Clock for VGA port.
These signals are true open drain, and do not pull-down to ground when power is not applied to the device. 
This pin requires an external pull-up resister.

47

DSDA4

I/O

DDC I2C Data for VGA port. 
These signals are true open drain, and do not pull-down to ground when power is not applied to the device. 
This pin requires an external pull-up resister.

55

TPWR_CI2CA

I/O

I2C Slave Address input/Transmit Power Sense Output. 
At the end of power -on-reset (POR), this pin is used as an input to latch the I2C sub-address. The level on 
this pin is latched when the POR transitions from the asscred state to the de-asserted state. After complec-
tion of POR, this pin is used as the TPWR output, indicating that the selected HDMI input port is receiving an 
active TMDS clock. This pin has an internal pull-up to the MICOMVCC33 power supply. If this signal is 
pulled-down, a 4.7L

Ω resister should be used. 

Note: There is a probability the POR logic may power up and not latch the level on this pin. A software 
workaround is required to determine the proper I2C slave address.

52

INT

O

Interrupt Output. 
This is an open_drain output and requires an external pull_up resister.

RSVD

 -

When SBVCC(pin38)=5V, RSVD pin #10 must be tied to GND with less than 10K resistor. When 
SBVCC(pin38)=3.3V, RSVD pin #10 must be tied to GND with 1M ohm resistor.
