Quick Start Guide
•
SW6 – SD_TH = F (default signal detect threshold level): Set switches (3-2-1) = (OFF-OFF-OFF).
•
SW6 – LPBK-RES = F (normal operation): Set switches (6-5-4) = (OFF-OFF-OFF).
•
SW7 – RESET = 0 (enables the device): Set switch pin 2 to the
ON
position.
•
SW9 – RX_DET = F (enables RX detection): Set switches (3-2-1) = (OFF-OFF-OFF).
•
SW9 – RES2 = F (normal operation): Set switches (6-5-4) = (OFF-OFF-OFF).
4. Connect 50
Ω
SMA cables to the board depending on the desired input and output channels:
•
The input signals J1 to J8 can be connected from a pattern generator.
•
The output signals J9 to J16 can be connected to a scope.

5. Pin Mode – Set the input equalization level:
•
Set ENSMB = 0 (1 k
Ω
to GND) by using SW2 (3-2-1) = (
ON
-OFF-OFF).
•
Set SW4 switches 1 and 2 to the OFF positions so the SMBus signals are disconnected.
•
Refer to
for information on 3-switch settings for the 4-level input.
•
[Example] Set EQA to Level 3: SW8 (3-2-1) = (OFF-OFF-OFF) = EQA = F

NOTE:
For normal operation in pin mode, ensure that RES3 SW8 (6-5-4) = (
ON
-OFF-OFF) and
AD2 SW1 (6-5-4) = (
ON
-OFF-OFF).
6. Pin mode: Set the output VOD level:
•
Set ENSMB = 0 (1 k
Ω
to GND) by using SW2 (3-2-1) = (
ON
-OFF-OFF).
•
Set SW4 switches 1 and 2 to the OFF positions so the SMBus signals are disconnected.
•
Refer to
for information on 3-switch settings for the 4-level input.
•
[Example] Set VODB[1:0] to Level 4: SW5 (6-5-4), (3-2-1) = (OFF-
ON
-OFF), (OFF-OFF-OFF) =
VODB[1:0] = R, F
