PEMIxCSP family

4-, 6- and 8-channel passive filter network with ESD protection

7.2 Use cases

The selection of one of the filter device has to be performed in dependence of the

maximum clock frequency, the driver strength, the capacitive load of the sink and the

maximum applicable rise and fall times.

7.3 LCD interfaces, medium-speed interfaces

For digital interfaces such as Liquid Crystal Display (LCD) interfaces running at clock

speeds between 10 MHz and 25 MHz or more, the devices can be used in dependence of

the sink load, the clock speed, the driver strength and the rise and fall time requirements.

The minimum EMI filter requirements may be an important factor, too.

7.4 Keypad, low-speed interfaces

Especially for lower-speed interfaces such as keypads, low-speed serial interfaces and

low-speed control signals, the PEMIxCSP family offers a very robust ESD protection and

strong suppression of unwanted frequencies (EMI filtering). Due to their small size the

devices can easily be spread on a Printed-Circuit Board (PCB) in order to move the

ESD and EMI protection close to the part of the design which shall be protected.
