CONTROL PINS(2)
OE 42 I Operation Enable/Reset Pin
OE = L: Power Down Mode
OE = H: Normal Operation
Internal weak pull up: Resets device when transitions from H to L
SIG_EN 17 I Signal detector circuit enable
SIG_EN = L: Signal Detect Circuit Disabled: Term resistors always connected (Default)
SIG_EN = H: Signal Detect Circuit Enabled: When no valid clock device enters Standby Mode.
Internal weak pull down
PRE_SEL 20 I
3-Level		 De-emphasis Control when I2C_EN/PIN = Low.
PRE_SEL = L: -2 dB
PRE_SEL = No Connect: 0 dB
PRE_SEL = H: Reserved
When I2C_EN/PIN = High; De-emphasis is controlled through I2C
EQ_SEL/A0 21 I 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 address
I2C_EN/PIN 10 I I2C_EN/PIN = High; Puts Device into I2C Control Mode
I2C_EN/PIN = Low; Puts Device into Pin Strap Mode
SCL_CTL 15 I/O I2C Clock Signal when I2C_EN/PIN = High.
Note: When I2C_EN = Low; Pin strapping takes priority and those functions cannot be changed by I2C
SDA_CTL 16 I/O I2C Data Signal when I2C_EN/PIN = High
Note: When I2C_EN = Low; Pin strapping takes priority and those functions cannot be changed by I2C
VSadj 22 I TMDS Output Voltage Swing Control; Nominal 7.06 kΩ Resistor to GND
A1 27 I High address bit 2 for I2C programming
Weak internal pull down.
Note: When I2C_EN/PIN = Low for Pin Strapping Mode leave this pin as No connect
TX_TERM_CTL 36 I
3-Level		 Transmit Termination Control
TX_TERM_CTL = H: No transmit Termination
TX_TERM_CTL = L: Reserved
TX_TERM_CTL = No Connect: Automatically selects the termination impedance
2 Gbps > DR ≤ 3.4 Gbps – 150 - 300 Ω differential near end termination
DR < 2 Gbps – no termination
Note: If left floating; the device will be in Automatic Select Mode. DR stands for Data Rate
SWAP/POL 1 I
3-Level		 Receive Polarity Swap and Receive Lane Swap control pin
SWAP/POL = H: Receive Lanes Polarity Swap (Retimer Mode Only)
SWAP/POL = L: Receive Lanes (Retimer and Redriver Mode)
Swap SWAP/POL = No Connect, Normal Operation
NC 18, 40 – No connect
(1) (1) G = Ground, I = Input, O = Output, P = Power
(2) (H) Logic High (Pin strapped to VCC through 65 kΩ resistor); (L) Logic Low (Pin strapped to GND through 65 kΩ resistor); (Mid-Level = No connect)
