Table 1. Switches to set the 4-level input control pins
4 – level Input Settings
Setting for 3 pin switches (3-2-1)
0 – Tie 1k ohm to GND
ON – OFF – OFF
R – Tie 20k ohm to GND
OFF – ON – OFF
F – FLOAT (open)
OFF – OFF – OFF
1 – Tie 1k ohm to VIH
OFF – OFF – ON
The following switches are used to set the input condition for the 4-level inputs:
SW1, SW2, SW3, SW5, SW6, SW8, SW9.
There are 3 switches connected to an input signal pin. Each switch when set to the ON position sets the pin to one
of the 4-level setting. The 6 pin switches are assigned similar to the 3 pin switches. The only difference is 2 signal
pins are connected and thus 6-5-4 is for the one signal pin and 3-2-1 is for another signal pin. Please note only 1
switch at the ON position is allowed.

See the datasheet for additional information on SMBUS.
J18
EEPROM
Optional socket for EEPROM
SW1
EQB[1:0] or AD[3:2]
PIN MODE – EQ control for channel B inputs
SMBUS MODE – AD[3:2] device address bits
SMBUS MODE – AD[3:2] device address bits
SW2
ENSMB
ENSMB = LOW – PIN MODE
ENSMB = HIGH – SMBUS (slave mode)
ENSMB = FLOAT – SMBUS (master mode – load configuration from EEPROM)
ENSMB = HIGH – SMBUS (slave mode)
ENSMB = FLOAT – SMBUS (master mode – load configuration from EEPROM)
SW3
DEMA[1:0]
PIN MODE – DE control for channel A outputs
SW4
SDA/SCL
“ON” position connects SDA and SCL lines to the device pin.
SW5
DEMB[1:0] or
AD[1:0]
PIN MODE – DE control for channel B outputs
SMBUS MODE – AD[1:0] device address bits
SMBUS MODE – AD[1:0] device address bits
SW6
SD_TH and LPBK -
RES
SD_TH – Signal detect threshold level (FLOAT = Default level)
LPBK function for PCI402 and RESERVED for PCI800 (FLOAT = Normal
operation)
LPBK function for PCI402 and RESERVED for PCI800 (FLOAT = Normal
operation)
SW7
VDD_SEL and PRSNT
VDD_SEL – Enable or disable the internal 3.3V to 2.5V regulator.
PRSNT – Enable or disable the device (LOW – Enables the device)
PRSNT – Enable or disable the device (LOW – Enables the device)
SW8
EQA[1:0]
PIN MODE – EQ control for channel A inputs
SW9
RXDET and RATE
RXDET – Input internal 50 ohm to VDD terminations
RXDET = F (AUTO RX Detect), RXDET = 1 (50 ohm input termination).
RATE = 0 (GEN1,2) = 2.5G / 5.0G.
RATE = R (GEN3) = 8.0G.
RATE = F (AUTO Detect). The RATE auto detect circuit requires the idle and active
signal which occurs during the link training negotiation.

SW10
READ_EN
ENSMB = FLOAT – SMBUS (master mode – load configuration from EEPROM)
SW6: SD_TH becomes the READ_EN pin.
To start the loading at power up, set SW6 pin 3 to “ON” position (pull to GND).
To manually control the start, set SW6 pin 1 to “ON” position (pull to VDD) and
push the SW10 button for the high to low transition to start the loading.
When the loading is complete the LED – D1 light should turn OFF.
