Termination Control (0x00)
1:0
Reserved
Set to 00.

Data Termination
0: TMDS Data inputs terminated into 50
Ω (normal
operation)
1: TMDS Data inputs terminated into 100
Ω (for paralleled
inputs)
5:3
Reserved
Set to 000.

Clk Termination
0: TMDS Clock inputs terminated into 50
Ω (normal
operation)
1: TMDS Clock inputs terminated into 100
Ω (for paralleled
inputs)
7
Reserved
Set to 0.
0x05
Output Options (0x00)
0
Tri-state Clock
Outputs
0: Normal Operation
1: Clock outputs tri-stated (allows another chip to drive the
output clock pins)
1
Tri-state Data
Outputs
0: Normal Operation
1: Data outputs tri-stated (allows another chip to drive the
output data pins)
2
Invert Output
Polarity
0: Normal Operation
1: The polarity of the TMDS data outputs is inverted
(+ becomes -, - becomes +). TMDS clock unchanged.
3
Reverse Output
Order
0: Normal Operation
1: CH0 data is output on CH2 and CH2 data is output on
CH0. No change to CH1.
0x06
Data Output Drive (0x00)
3:0
Transmit Current
Transmit Drive Current for data signals, adjustable in
0.125mA steps. Clock current is fixed at 10mA.
0x0: 10mA
0x8: 11mA
0xF: 11.875mA
7:4
Transmit
Pre-emphasis
Drive boost (in 0.125mA steps) added during first half of
each bit period for data signals. Clock signals do not have
pre-emphasis.
0x0: 0mA
0x8: 1mA
0xF: 1.875mA
0x07
Reserved (0xCC)
7:0
Reserved
Default value of 0xCC is OK, can also be set to 0x00.
0x08
Equalization (0xCC)
3:0
Equalizer Gain
Boost (dB) = 1dB + <gain value> * 0.8dB
0x0: 1dB boost at 800MHz
0xC: 10.6dB boost at 800MHz (default)
0xF: 13dB boost at 800MHz
7:4
Reserved
Default value of 0xC is OK, can also be set to 0x0.
0x09
Test Pattern Generator (0x00)
1:0
Generator Mode
When a 25MHz to 165MHz clock is applied to the clock
input, this function will output a PRBS7 pattern on the TX
pins.
0: Normal operation (test patterns disabled)
1: PRBS7 pattern
2: Low frequency toggle (0000011111…)
3: High frequency toggle (1010101010…)
Note: When switching from the high frequency toggle
pattern to the low frequency toggle pattern, you must first
select normal operation.
2
Enable PRBS7 Error
Counter
Enables PRBS7 error counter in registers 0x0A to 0x0C.
0: Disable PRBS7 Error Counter
1: Enable PRBS7 Error Counter
