VIDEO_TX

CMOS input for video flow direction

1: video serializer

0: video deserializer

29, 30

SDA, SCL

31 to 34

I2CA[3:0]

16

RSTB/PDB

CMOS input for Reset and Power-down. For normal operation, this pin must be forced high. When

this pin is forced low, the device will be reset. If this pin stays low, the device will be in PD mode.

14

STATUS

CMOS output for Receiver Status:

1: Valid 8b/10b data received

0: otherwise

Note: serializer and deserializer switch roles during side-channel reverse traffic

36

REF_RES

Analog bias setting resistor connection; use 3.16k

Ω ±1% to ground

27

GND_P

PLL Ground

48, 64

GND_IO

Digital (Parallel and Control) Ground

44, 45

GND_CDR

Analog (Serial) Data Recovery Ground

39, 42

GND_TX

Analog (Serial) Output Ground

37

GND_AN

Analog Bias Ground

17, 18

GND_CR

Core Logic Ground

19, 20

VDD_CR

Core Logic VDD

43

VDD_TX

Analog (Serial) Output VDD

38

VDD_AN

Analog Bias VDD

46, 47

VDD_CDR

Analog (Serial) Data Recovery VDD

NOTES:

3. Pins with the same name are internally connected together. However, this connection must NOT be used for connecting together external

components or features.

4. 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.
