Termination Impedance Select bit 1:
Termination Impedance Select bit 0:
In the
Hardware mode and in the internal termination mode (TXTSEL=”1” and RXT-
SEL=”1”) TERSEL[1:0] control the transmit and receive termination impedance
according to the following table.
In the
internal termination mode the receiver termination of each receiver is realized
completely by internal resistors or by the combination of internal and one fixed external
resistor (see description of RXRES[1:0] pins).
In the
internal termination mode the transformer ratio of 1:2 or 1:2.45 and 1:1 is
required for transmitter and receiver respectively with the transmitter output AC cou-
pled to the transformer.
NOTES:
1.
This pin is internally pulled “Low” with a 50k
Ω resistor.
2.
In Hardware mode, all channels share the same TERSEL control function.
3.
In the external termination mode a 1:2 or 1:2.45 transformer ratio must be
used for the transmitter.
TEST

Manufacturing Test:
NOTE: For normal operation this pin must be tied to ground.
ICT

In-Circuit Testing (Active “Low”):
When this pin is tied “Low”, all output pins are forced to a high impedance state for in-
circuit testing.
Pulling RESET and ICT pins “Low” simultaneously will put the chip in factory test
mode. This condition should not be permitted during normal operation.
NOTE: This pin is internally pulled “High” with a 50k
Ω resistor.
