3.2. BTB Connector

The BTB connector is used to connect TE-A to UMTS&LTE EVB. Most module pins are connected to
BTB1 connector; some pins are connected directly to TE-A's peripheral circuit or test points; and no pins
are connected to BTB2 connector.
Module signals derived from BTB1 connector are listed below:
⚫
PCM
⚫
I2C
⚫
RESET_N
⚫
PWRKEY
⚫
ADC1

STATUS_N
⚫
NET_STATUS
⚫

To synchronize with the indication LEDs on UMTS&LTE EVB, an inverter is added to the STATUS output signal of
BG770A-GL, therefore the signal of BTB1 connector is defined as "STATUS_N".
