In the event of a discrepancy in values between this guide and the Product Specification Document (PSD), the PSD takes precedence.
Overview of operation
Note: This chapter contains information for CDMA (MC57xx) and
GSM (MC8xxx) modules.
Information that is unique to specific module types is clearly
identified.
The module is designed to use a 3.3 V (nominal) power supply
(3.8 V nominal on MC8201), provided by the host. It is the
host's responsibility to provide safe and continuous power to
the module at all times; the module does NOT have an
independent power supply, or protection circuits to guard
against electrical issues.
The module's power state is controlled by the host's assertion /
de‐assertion of the
W_Disable#
monitors its supply voltage and requests shutdown if the
supply is insufficient.
Power signals
The module must be connected to a 3.3 V power supply (3.8 V
for MC8201), as described in PCI Express Mini Card Electrome‐
chanical Specification Revision 1.1.
The MC8xxx has more power pins than the MC57xx due to
higher peak current requirements for GSM devices.
For detailed pinout and voltage / current requirements of these
modules, see the Product Specification Document for your
Mini Card.
Electrostatic discharge (ESD)
You are responsible for ensuring that the host has adequate
ESD protection on digital circuits and antenna ports:
•
(Operational) RF port (antenna launch and RF connector):
IEC‐61000‐4‐2 — Level (Electrostatic Discharge Immunity Test)
•
(Non‐operational) Host connector interface:
JESD22‐A114‐B +/‐ 1kV Human Body Model and
JESD22‐C101 +/‐ 125 V Charged Device Model
•
MC5728V only: (Non‐operational) Host connector interface:
JESD22‐A114‐B +/‐ 200V Human Body Model and
Proprietary and Confidential
signal. The module also
