Description

Pericom Semiconductor’s PI3V312 is a 4-port, 2:1 Multiplexer/ Demultiplexer with 3-state outputs. The switch introduces no ad- ditional ground bounce noise or propagation delay. Low On-Resistance and High bandwidth make it ideal for video and other applications. Also this device has exceptionally low crosstalk and off-isolation, which is far greater than most analog switches offered today. A single 3.3V supply is all that is required for operation. The PI3V312 offers a high-performance (500MHz), low-cost solu- tion to switch between video signals that have high bandwidth.

Low On-Resistance, 3.3V High-Bandwidth 4-Port, 2:1 Mux/DeMux VideoSwitch Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 2. Typical values are at VCC = 3.3V , +25°C ambient. 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 = 3.3V , TA = 25°C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. Measured by the voltage drop between Y and In pin at indicated current through the switch. On-Resistance is determined by the lower of the voltages on the two (Y , In) pins. 5. This parameter is determined by device characterization but is not production tested. Power Supply Characteristics Parameters Description Test Conditions(1) Min. Typ.(2) Max.

See test circuit and waveforms. 2. This parameter is guaranteed but not tested on Propagation Delays. 3. The 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 0.30ns for 10pF 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 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.

Low On-Resistance, 3.3V High-Bandwidth 4-Port, 2:1 Mux/DeMux VideoSwitch Applications Information Logic Inputs The logic control inputs can be driven upto 3.6V regardless of the supply voltage. For example, given a +3.3V supply, EN maybe driven LOW to 0V and HIGH to 3.6V . Driving EN Rail-to-Rail® minimizes power consumption. Power Supply-Sequencing Proper power supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the input/ output or control pins. Hot Insertion For Datacom and Telecom applications that have ten or more volts passing through the backplane, a high voltage from the power supply may be seen at the device input pins during hot insertion. The PI3V312 device have maximum limits of 6V and 120mA for 20ns. If the power is higher or applied for a longer time or repeatedly reaches the maximum limits, the devices can be damaged.
