CONTROL PINS
OE 36 I Operation enable/reset pin
OE = L: Power-down mode
OE = H: Normal operation
Internal weak pullup: Resets device when transitions from H to L
SLEW_CTL 34 I
3
level (1)		 Slew rate control when I2C_EN/PIN = Low. SLEW_CTL = H, fastest data rate (default)
SLEW_CTL = L, 5-ps slow
SLEW_CTL = No Connect, 10-ps slow
When I2C_EN/PIN = High Slew rate is controlled through I2C[4]
PRE_SEL 16 I
3
level (1)		 PRE_SEL = L: - 2-dB de-emphasis
PRE_SEL = No Connect: 0-dB
PRE_SEL = H: Reserved
Note: (3 level for pin strap programming, but 2 level when I2C[4] address)
EQ_SEL/A0 17 I
3
level (1)		 Input Receive Equalization pin strap when I2C_EN/PIN = Low
EQ_SEL = L: Fixed EQ at 7.5-dB
EQ_SEL = No Connect: Adaptive EQ
EQ_SEL = H: Fixed at 14-dB
When I2C_EN/PIN = High
Address bit 1
Note: (3 level for pin strap programming but 2 level when I2C[4] address)
I2C_EN/PIN 8 I I2C_EN/PIN = High; puts device into I2C control mode
I2C_EN/PIN = Low; puts device into pin strap mode
SCL_CTL 13 I I2C clock signal
Note: When I2C_EN/PIN = Low Pin strapping take priority and those functions cannot be changed by I2C
SDA_CTL 14 I/0 I2C data signal
Note: When I2C_EN/PIN = Low Pin strapping take priority and those functions cannot be changed by I2C
Vsadj 18 I TMDS-compliant voltage swing control nominal resistor to GND
HDMI_SEL/A1 23 I HDMI_SEL when I2C_EN/PIN = Low
HDMI_SEL = High: Device configured for DVI
HDMI_SEL = Low: Device configured for HDMI (Adaptor ID block is readable through I2C
When I2C_EN/PIN = High
Address bit 2
Note: Weak internal pull down
SUPPLY AND GROUND PINS
VCC 11, 37 P 3.3-V power supply
VDD 12, 19, 20, 31, 40 P 1.1-V power supply
GND 15, 35, Thermal Pad — Ground
(1) (H) Logic high (pin strapped to VCC through 65-kΩ resistor); (L) logic low (pin strapped to GND through 65-kΩ resistor); (for mid-level, no connect)
