Application Circuit

(1) Ground Planes:

REB-3300 GPS receiver needs two different ground planes. The GND_A pin(11、

12、13、14、15、16、18) shall be connect to analog ground.

The GND pin(2、10、30) connect to digital ground.

(2) Serial Interface:

The Serial interface pin(RXA、TX1、TXB、RXB) is recommended to pull up(10KΩ).

It can increase the stability of serial data.

(3) Backup Battery:

It’s recommended to connect a backup battery to V_BAT.

In order to enable the warm and hot start features of the GPS receiver. If you don’t

intend to use a backup battery, connect this pin to GND or open.

If you use backup battery, shall need to add a bypassing capacitor (10uF) at V_bat

REB-3300 Operational Manual

trace. It can reduce noise and increase the stability.

(4) Antenna:

Connecting to the antenna has to be routed on the PCB. The transmission line must

to controlled impedance to connect RF_IN to the antenna or antenna connector of

your choice.

(5) Active antenna bias voltage:

The Vcc_RF pin(pin 20) is provide voltage 3.0V. If you use active antenna, you can

connect this pin to V_ANT_IN pin (pin 19) to provide bias voltage of active antenna.

The bias voltage will through RF_IN pin to provide active antenna bias voltage from

Vcc_RF pin.

If your bias voltage of active antenna isn’t 3.0V, you can input bias voltage to

V_ANT_IN pin(pin 19).And input bias voltage of you need. It can open if you use

passive antenna. The input bias voltage will through RF_IN pin to provide active

antenna bias voltage from V_ANT_IN pin.

The maximum power consumption of active antenna is about 100mW

(6) Power:

Connect Vcc pin to DC 3.3V.The power supply must add bypassing capacitor(10uF

and 1uF).It can reduce the Noise from power supply and increase power stability.
