Control Connector Signal Descriptions And Functions - Enfora Enabler II-G Integration Manual

Integration Guide
Version 1.01
6.7.2 RF Connector
The Enabler II-G utilizes an ultra Miniature Coaxial Interconnect from Sunridge (MCB-ST-00T) as the on-
board antenna connector. A compatible mating connector is the Sunridge MCB2-xx-xx-xxx-x series
component. The cable assembly is made to order. Maximum stack height of cable connector and PCB
connector is 2.0 mm.

6.8 Control Connector Signal Descriptions and Functions

6.8.1 Input Power
The Enfora Enabler II-G module uses a single voltage source of VCC=+3.3V to 4.5V. (exact values of the
uplink currents are shown in Tables5.3.1 GSM Operating Power and 5.3.2 GPRS Operating Power). The
V lines (pins 1 to 6) should be connected on the application board.
CC
The uplink burst will cause strong ripple on the voltage
lines and should be effectively filtered. It is recommended
that 1000 to 2000 uF of capacitance be placed as close to
the modem I/O connector as possible.
!
It should be noted that the input voltage level should not
drop below the minimum voltage rating under any
circumstances, especially during the uplink burst period.
