Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 6.2V, TA = 25°C ambient temperature.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. VON (min) value is at VCC = 6.1V, TA = 70°C.
5. The expected AC VON value is about 125 mV higher than the DC VON value using the similar test circuit in Figure 10 with VIN swing from 0.0V
to 4.5V at 10 MHz sine wave.
6. The value of RON of M1 is calculated with the equvalent mathematical formula of the test circuit in Figure 10.

Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested.
3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The
time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of
typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is
determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.

TALK
The PI5L100 was designed to switch between various standards
suchas 10Base-T, 100Base-T, 100VG-AnyLAN, andTokenRing.
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 11 applications).
Generally speaking, this LAN Switch can be used for data rates to
200 Mbps and data signal levels from 0V to 4.5V.
V

SignalDistortion
DifferentialCrosstalk...XTALK(DIF)
Adjacent pins cause the most crosstalk because of the interlead
package capacitance which is generally in the order of 0.5pF (pin-
to-pin). It can be seen in Figure 11 that this Evaluation (EV) Board
schematic uses four pairs of switches. Pair 1B/2B are RX1 that
connecttoYAandYB.Thesecondpair,3B/4B,areTX1andconnect
to YC and YB. Pairs 3 and 4 are grounded for this differential
crosstalk test. The purpose of this EV board is to determine the
Distortion of the input signal is equated to 20LOG ∆R / RL. So
ON
keeping R
flat as data signal level varies is critical to low
ON
distortion. Also, increasingthedatarateincreasesharmonicdistor-
tion which also effects the signal amplitude.
