Description
R
ON
Resistance between source and drain with switch in the ON state.
I
O
Output leakage current measured at S1, S2, and D with the switch OFF.
V
IN
Digital voltage at the IN pin that selects between S1 and S2 analog inputs.
V
EN
A voltage that ENABLES the chip.
C
IN
Capacitance at the digital inputs.
C
OFF
Capacitance at analog I/O (S1, S2, D) with switch OFF.
C
ON
Capacitance at analog I/O (S1, S2, D) with switch ON.
V
IH
Minimum input voltage for logic HIGH.
V
IL
Minimum input voltage for logic LOW.
I
IH
(I
IL
)
Input current of the digital input.
I
OS
Minimum short circuit current for S1, S2 and D.
t
ON
Propagation delay measured between 50% of the digital input to 90% of the analog output when switch
is turned ON. The peak analog voltage is 0.714V.
t
OFF
Propagation delay measured between 50% of the digital input to 90% of the analog output when switch
is turned OFF. The peak analog voltage is 0.714V.
B
W
Frequency response of the switch in the ON state measured at 3dB down.
X
TALK
Is an unwanted signal coupled from channel to channel. Measured in dB. X
TALK
= 20 LOG V
OUT

IN
.
This is non-adjacent crosstalk.
D
G
Differential gain is the difference measurement between two bias levels, for instance analog input signals
of 0V to 0.714V.
D
P
Differential phase is the difference measurement between two bias levels, for instance analog input signals
of 0V to 0.714V.
O
IRR
Off isolation is the resistance (measured in dB) between the input and output with the switch off (NO).
LAN Switch
The PI3V330 was designed to switch between various standards
such as 10Base-T, 100Base-T, 100VG-AnyLAN, and Token Ring.
Also general purpose applications such as loopback, line termina-
tion, and line clamps that might normally use mechanical relays are
also ideal uses for this LAN Switch (see Figure 1). Generally
speaking, this LAN Switch can be used for data rates to 200 Mbps
and data signal levels from 0V to 3.6V.
V
CC
Bias Voltage vs. R
ON
To keep R
ON
to a minimum, it is recommended that the V
CC
voltage
be increased to a voltage between 3.3V and 3.6V. Ideally an input
voltage between 0.2V and 3.6V will keep R
ON
flat.
Signal Distortion
Distortion of the input signal is equated to 20LOG
R
ON
/R
L
. So
keeping R
ON
flat as the data signal level varies is critical to low
distortion. Notice that increasing the data rate increases harmonic
distortion which also effects the signal amplitude
.
