7.2 Use cases
7.3 LCD interfaces, medium-speed interfaces
7.4 Keypad, low-speed interfaces
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.
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.
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.
