Application note
5.1.1 Application details of IP4252CZ12-6 and IP4252CZ16-8
Table 10.
Due to the integrated symmetrical pi-filter structure, also often referred to as CRC
structure, all NXP Semiconductors IP425x devices offer a direction-independent and
symmetrical ESD protection as well as a direction-independent and symmetrical EMI filter
performance.
The integrated pi-filter structures result in a very low ESD clamping voltage compared to
single diode ESD protection implementations and/or devices.
The schematic drawing depicted in
and/or IP4252CZ16-8 in an SD-memory card interface including both options for card
detection. The grey-colored components are optional and depend on the exact details of
the interface implementation. Especially with respect to the card detect mechanism, either
using a mechanical switch in the card holder (preferred according
integrated pull-up resistor at pin DAT3/CD in combination with selectable pull-down /
pull-up resistors, the exact resistor values have to be aligned with all details described in
Ref.
This schematic does not include details concerning card-supply and typical power-supply
decoupling capacitors.
For the basic SD-memory card operation an IP4252CZ12-6 and 4 pull-up resistors
(10 kΩ to 100 kΩ) are sufficient for the digital data transmission from and to the
SD-memory card. MMCs require higher pull-up resistor values starting at 50 kΩ. The
card-detection mechanism has to be implemented using a CD channel as depicted in
Figure
with the same interface.
