DESCRIPTION
SERIALIZER
DESERIALIZER
CMOS input for HSYNC and VSYNC Polarity
1: HSYNC & VSYNC active low
0: HSYNC & VSYNC active high
CMOS input for video flow direction
1: Video serializer
0: Video deserializer
I²C Interface Pins (I²C DATA, I²C CLK), weak internal pullup
I²C Device Address
I²C Master Mode
1: Master
0: Slave
CMOS input for Reset and Power-down. For normal operation, this pin should be driven high. When this
pin is taken low, the device will be reset. If this pin stays low, the device will be in PD mode.
CMOS output for Receiver Status:
1: Valid 8b/10b data received
0: No valid data detected
Note: serializer and deserializer switch roles during side-channel reverse traffic
Analog bias setting resistor connection; use 3.16kΩ ±1% to ground

TEST_EN
Must be connected to ground
Exposed Pad
PAD
Must be connected to ground, not an electrical connection
NOTES:
1. Pins with the same name are internally connected together. However, this connection must NOT be used for connecting together external components
or features.
2. The various differently-named Ground pins are internally weakly connected. They must be tied together externally. The different names are provided
to assist in minimizing the current loops involved in bypassing the associated supply VDD pins. In particular, for ESD testing, they should be
considered a common connection.
