Description

Pericom Semiconductor’s PI5L100 is a Quad 2:1 multiplexer/ demultiplexer LanSwitch with three-state outputs. This device can be used for switching between various standards, such as 10 Base- T, 100 Base-T, 100VG-AnyLAN or Token Ring. Generally, this part can be used to replace mechanical relays in low voltage LAN applications that have phsical layer, unshielded twisted pair media (UTP) with either CAT 3 or CAT 5 grade cable. To reduce insertion loss, PI5L100 is powered by a 6.2V Zener voltage. ES A YB YC YD Yn oitcnuF HX Z -iHZ -iHZ -iHZ -iHe lbasiD LL 0 AI0 BI0 CI0 DI0 =S LH 1 AI1 BI1 CI1 DI1 =S 20-Pin L PI5L100

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at V CC = 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. V ON (min) value is at VCC = 6.1V, TA = 70°C. 5. The expected AC V ON 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 R ON of M1 is calculated with the equvalent mathematical formula of the test circuit in Figure 10. Maximum Ratings (Above which useful life may be impaired.

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 cap acitance. 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 r ise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when use d 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.

Applications

1 and 2 are single ended inputs to the differential inputs of the DUT. Trace 3 is the differential X TALK output which equates to 20LOG VOUT/VIN = 20LOG 30 mV/5V = –44dB. Since the edge rate is 2ns, the effective input frequency is equal to 0.3/tR which is ~150 MHz. So the approximate Differential Crosstalk at 150 MHz is –44dB. Because pins measured are not adjacent, the differential crosstalk is typically > 60 dB at 10 MHz. The load resistor (RL) used was 100 ( to match the UTP impedance). Increasing the data rate or RL will also increase differential crosstalk. VCC Bias Voltage vs RON To keep RON to a minimum, it is recommended that the VCC voltage be increased to a voltage between +6.0V and +6.5V (see Figure 13). The R ON vs. VIN curve shows the effect of on-resistance and input voltage which is exponential. Ideally an input voltage between 0.2V and 3.6V will keep R ON in the flat part of the curve (∆RON or flatness is ~2 ohms). Signal Distortion Distortion of the input signal is equated to 20LOG ∆R ON/ RL. So keeping R ON flat as data signal level varies is critical to low distortion. Also, increasing the data rate increases harmonic distor- tion which also effects the signal amplitude. Evaluation Board Figure 14 shows the layout for an EV board that can be used for evaluation. This is a 2-layer board and is one-inch square.
