1. Product profile
1.1 General description
The IP425x family consists of 4-, 6- and 8-channel RC low-pass filter arrays which are
designed to provide filtering of undesired RF signals on the I/O ports of portable
communication or computing devices. In addition, the IP425x family incorporates diodes
to provide protection to downstream components from ElectroStatic Discharge (ESD)
voltages as high as ±30 kV.
The IP425x family is fabricated using monolithic silicon technology and integrates up to 8
resistors and 16 diodes in a 0.4 mm pitch 8-, 12- or 16-pin MicroPak (compatible with
QFN) lead-free plastic package with a height of 0.5 mm only.

7. Application information
7.1 Insertion loss
The IP425x family is mainly designed as EMI/RFI filters for multi-channel interfaces. The
measured insertion loss in a 50 Ω system for IP4251, IP4253 and IP4254 and the
simulated insertion loss for IP4252 is depicted in Figure 2.
The insertion loss was measured using the test set-up as depicted in Figure 1.

Fig 5. IP4253 frequency response curves
Fig 6. IP4254 frequency response curves
Due to the optimized silicon dice and package design, all channels in a single package
show a very good matching performance as the insertion loss for a channel at the
package side (e.g. ch1 to ch16) is nearly identical with the center channels (e.g. ch4 to
ch13). Typical measurements results are shown in Figure 3 to Figure 6 for the different
devices.
7.2 Selection
The IP425x family is mainly designed as EMI/RFI filters for multi-channel interfaces. The
selection of one of the filter devices has to be performed dependent on the maximum
clock frequency, driver strength, capacitive load of the sink, and also the maximum
applicable rise and fall times.
7.2.1 SD(HC) and MMC memory interface
The Secure Digital High Capacity (SDHC) memory card interface standard specification
and the MultiMediaCard (MMC) (JESD 84A43) standard specification recommend a rise
and fall time of 25 % to 62.5 % (62.5 % to 25 % respectively) of 3 ns or less for the input
signal of the receiving interface side.
Assuming a typical capacitance of about 20 pF for the SDHC memory card itself, and
approximately 4 pF to 7 pF for the PCB and the card holder, IP4252CZ12-6 (6 channels,
Rs(ch) = 40 Ω, Cch = 12 pF at Vbias(DC) = 2.5 V) is a matching selection to filter and protect
all relevant interface pins such as CLK, CMD, and DAT0 to DAT3/CD. Please refer to
Figure 7 for a general example of the implementation of the IP4252 in an SD(HC) card
interface.
In case additional channels such as write-protect or a mechanical card detection switch
are used, the IP4252CZ16-8 (8 channels, Rs(ch) = 40 Ω, Cch = 12 pF at Vbias(DC) = 2.5 V)
offers two additional channels.

Fig 7. Example of IP4252 in an SD(HC) card interface
The capacitance values specified for the signal channels of the MMC interface differ from
the SD(HC) specification. The MMC card side interface is specified to have an intrinsic
capacitance of 12 pF to 18 pF and the total channel is limited according the specification
to 30 pF only. Therefore, any filter device capacitance is limited to a maximum of up to
18 pF, including the card holder and PCB traces.
Please refer to Figure 8 for a general example of the implementation of the IP4252 in a
MultiMediaCard interface application.

Fig 8. Example of IP4252 in an MMC interface
To generate SDHC- and MMC-compliant digital signals, the driver strength should not
significantly undercut 8 mA.
7.2.2 LCD interfaces, medium-speed interfaces
For digital interfaces such as LCD display interfaces running at clock speeds between
10 MHz and 25 MHz or more, IP4251, IP4252, or IP4254 can be used in dependency of
the sink load, clock speed, driver strength and rise and fall time requirements. Also the
minimum EMI filter requirements may be a decision-making factor.
7.2.3 Keypad, low-speed interfaces
Especially for lower-speed interfaces such as keypads, low-speed serial interfaces (e.g.
RS232) and low-speed control signals, IP4253 (Rs(ch) = 200 Ω, Cch = 30 pF at
Vbias(DC) = 2.5 V) offers a very robust ESD protection and strong suppression of unwanted
frequencies (EMI-filtering).
