Note: ESD protection is highly recommended for the USIM / RUIM
connector at the point where the contacts are exposed, and for any
other signals from the host interface that would be subjected to ESD
by the user of the product.
Module power states
Note: The module unit defaults
to the Normal state when
VCC3.3 is first applied in the
absence of W_Disable# control.

Disconnected state
Note: The difference between
the Disconnected and Off states
is that in the Off state, the

Values in this guide are summarized from the product specification documents (PSDs) - the PSD takes precedence.
Device-generated RF
Note: The module can cause
interference with other devices
such as hearing aids and on-
board speakers.
Wireless devices such as the
Mini Card transmit in bursts
(pulse transients) for set
durations (RF burst frequencies).
Hearing aids and speakers
convert these burst frequencies
into audible frequencies,
resulting in audible noise.

Note: In practice, there are usually numerous interfering frequencies
and harmonics. The net effect can be a series of desensitized receive
channels.
Note: It is important to
investigate sources of localized
interference early in the design
cycle.
