3.7.1 USIM card reference circuit
CLM920_TD5 Mini PCIE module without USIM card slot, users need to design a USIM
card slot on your own interface card.
USIM card interface reference design diagram is as follow:
Figure 3- 14 USIM design circuit
① Recommended ONSEMI company’s SMF15C for ESD protection on the
interface line, peripheral circuit devices should be placed near the card slot. Keep layout
of USIM card as close to the module as possible.
② USIM card will lost or become unavailable when disturbed by RF, so the USIM
