B10
External termination resistor. A 1% 1K ohm resistor must be connected from this pin to AVDD_3.3
(3.3V analog power supply). This termination resistor determines current references for both the DVI
receiver block and Analog HSYNC Delay block for both DVI and analog configurations.

For the gm5060-H (HDCP-enabled), this pin is used for DDC Interface for DVI-HDCP
communication. This is SCL for slave-only DDC communication.
[Input, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
DDC_SCL
I
N2
For the gm5060 (non-HDCP), this pin is an unused CMOS input that may be left unconnected.
However, it is preferred that this pin be connected to a known logic state.
For the gm5060-H (HDCP-enabled), this pin is used for DDC Interface for DVI-HDCP
communication. This is SDA for slave-only DDC communication.
[Bidirectional, 4mA drive output, Schmitt trigger input (400mV typical hysteresis), 5V-tolerant]

IO
N3
For the gm5060 (non-HDCP), this pin is an unused CMOS input that may be left unconnected.
However, it is preferred that this pin be connected to a known logic state.
