Functional connection
Figure 13 shows a partial diagram of the PCK2023 in an application.
The host outputs are differential current drivers, therefore the output
current is converted to a voltage by using some type of load resistor
(in this case, R
S
and R
P
). The output current is based on two, the
value of R
ref
and the setting on MULTSEL0 and MULTSEL1 pins.
The I
ref
pin is actually a reference voltage which is fixed at 1.1 volts,
therefore, I
ref
is 1.1/R
ref
. There are limitations on how large the
current can be made. This is coupled to the termination resistors
used. The maximum voltage which should be observed at the HOST
or HOST pins of the PCK2023 is 1.1 volts. This value may be
determined by using:
V
max
(

R
P

N
mult
1.1
R
ref
where R
S
and R
P
are the termination resistor values, N
mult
is the
current multiplier set by MULTSEL0 and MULTSEL1, and R
ref
is the
current reference resistor. V
max
should not exceed 1.1 volts
because of the internal current source configuration.
