OE_N

Input

Enable for level shifter path. 3.3 V tolerant low-voltage

single-ended input. Internal pull-down enables chip

when unconnected

SCL_SINK

Output

5 V DDC Clock I/O. Pulled-up by external termination

to 5 V. Connected to SCL_SOURCE through voltage-

limiting integrated NMOS pass-gate

SDA_SINK

I/O

5V DDC Data I/O. Pulled-up by external termination to

5V. Connected to SDA_SOURCE through voltage-

limiting integrated NMOS pass-gate

HPD_SINK

Input

Low-frequency, 0V to 5V (nominal) input signal. This

signal comes from the HDMI connector. Voltage high

indicates “plugged” state; voltage low indicates

“unplugged” state. HPD_SINK is pulled down by an

integrated 160KΩ pull-down resistor

GND

Power

Ground

DDC_EN

Input

Enables bias voltage to the DDC pass-gate level shifter

gates. (May be implemented as a bias voltage

connection to the DDC pass-gate themselves)

VCC33

Power

3.3 V±10% DC supply

FUNCTION3

Input

Used for polarity control of the HPD_SOURCE output.

When L, the HPD_SOURCE is an open-drain output

sand when H, the HPD_SOURCE is a buffered output

(O V to VCC)

FUNCTION4

Vendor-specific

control or test

pins

Function pins are to enable vendor-specific features or

test modes

For normal operation, these pins are tied to GND or

VCC33

For consistent interoperability, GND is the preferred

default connection for these signals
