EB-5631RE

GPS Engine Board

Description
EB-5631RE GPS module features high sensitivity, low power and ultra small form factor. This GPS module is powered by SiRF Star IV, it can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. With SiRF CGEE (Client Generated Extended Ephemeris) technology, it predicts satellite positions for up to 3 days and delivers CGEE-start time of less than 15 seconds under most conditions, without any network assistance. Besides, MicroPower Mode allows GPS module to stay in a hot-start condition nearly continuously while consuming very little power.

EB-5631RE is suitable for the following applications: 
• Automotive navigation
• Personal positioning
• Fleet management
• Mobile phone navigation
• Marine navigation

OPERATING Description


RF_IN

This pin receives signal of GPS analog via external active antenna. It has to be a controlled impedance trace at 50ohm. Do not have RF traces closed the other signal path and routing it on the top layer. Keep the RF traces as short as possible.

GND

This is Ground pin for the baseband circuit.

VBAT

This is the battery backup power input for the SRAM and RTC when main power is off. Without the external backup battery, EB-365 will always execute a cold star after turning on. To achieve the faster start-up offered by a hot or warm start, a battery backup must be connected. The battery voltage should be between 2.0V and 3.5V.

NC

EB-5631RE reserves pin, Just NC.

VCC

This is the main power supply to the engine board. (3.1Vdc to 3.5Vdc)

RESET

Low Active, when EB-5631RE is accepted this single, EB-5631RE going to Hibernate mode. If want EB-5631RE up, need input ON_OFF single.

GPIO

User can use this I/O pin for special functions. (For example, control LED)

TIMEMARK

This pin provides one pulse-per-second output from the board, which is synchronized to GPS time. This is not available in Trickle Power mode. If do not use it, Just NC.

ON_OFF

The ON_OFF pin commands the EB-5631RE ON or OFF. There are multiple methods of connecting this pin for different applications in order to minimise host resource requirements.

The ON_OFF pin is used to command the EB-5631RE to turn on or off:

l   The turn on command is a hardware feature of the Power Control FSM based on sensing a rising edge on the pin.

l   The turn off command is a software feature based on interrupts related to rising and/or falling edges and/ or sensing of pin levels. (Not currently supported.)

The ON_OFF pin processing is carried out by the Power Control FSM. The ON_OFF rising edge event during low power modes is recorded in a status register that is subsequently read by the processor once it is running. When the processor is running at the time of an ON_OFF event, the processor can poll the status or set-up an interrupt.

WAKE_UP

System power controller, when EB-5631RE Power ON, this pin will output 1.8Vdc.

TXD

This is the main transmits channel for outputting navigation and measurement data to user’s navigation software or user written software. Output is TTL level, 0V ~ 2.85V.

RXD

This is the main channel for receiving software commands from SiRFDemo software or from your proprietary software.
