Page 22: Internal Lna
SE868-V3 Product User Guide Product Features Internal LNA The GNSS engine has an adjustable gain internal LNA which allows the receiver to compensate for the use of various external antennas. The default gain (low or high) is determined by the version of firmware installed in the module. -
Page 23: Power Management Modes
SE868-V3 Product User Guide Product Features Power Management Modes The receiver features several operating modes that provide reduced power consumption. Availability of GNSS signals in the operational environment will be a factor in choosing power management modes. The designer can choose a mode that provides the best trade-off of navigation performance versus power consumption. -

SE868-V3 Product User Guide Product Features 4.14.2.2. SmartGNSS II SmartGNSS II includes the benefits of SmartGNSS I and achieves further power reduction by minimizing the usage of the secondary GNSS constellation. The adaptive mechanism adjusts constellation usage based on signal conditions to maintain performance while minimizing power consumption. -
Page 25: Product Compatibility
The SE868-V3 offers an upgrade path from existing Telit and competitive designs to the SiRFstar5-B02. The SE868-V3 is footprint-compatible with the SE868-V2 and JF2 module families but it is not a drop-in replacement since some of the pins have a slightly different function. The designer will have to modify the antenna and possibly other components in the RF path to accommodate the GLONASS, BeiDou, and Galileo as well as the GPS signals. -

The module will power up into the state determined by the ON-OFF pin (High: RUN; Low: HIBERNATE). The power state of the SE868-V3 can be determined by monitoring the “SYSTEM-ON” signal. A logic low indicates the module is in OFF, RESET, HIBERNATE, or STANDBY; whereas logic high indicates the module is in RUN state. -

Page 40: Control (Input) Signals
Control (input) Signals ON-OFF (input) and SYSTEM-ON (output) The SE868-V3 module has three power states: OFF, RESET, and ON. The OFF state is when power is removed from the module. Upon initial application of power, the module enters the RESET state until the internal reset process is completed. -

SE868-V3 Product User Guide Electrical Interface Boot Select It is not necessary to use the Boot Select pin to re-flash the receiver since SiRFlive can use commands to perform this task. This pin should be left floating or (preferably) may be brought out to a test point. -
Page 42: Serial I/O Ports - Configuration And Operation
SE868-V3 Product User Guide Electrical Interface Serial I/O Ports - Configuration and Operation The receiver module includes two full-duplex serial ports which are configurable for the desired interface. Primary Port Configuration The primary port is configured for UART, I C or SPI interface via reading GPIO6 and GPIO7 pins at startup or reset (only). -
Page 43: Uart Operation
SE868-V3 Product User Guide Electrical Interface UART Operation See section 9.5.1 Primary Port Configuration to specify UART interface. The secondary port is configured by loading the appropriate FW. Default: NMEA at 9600 bps, 8-bit, No parity, and 1 stop bit. -
Page 44: I 2 C Operation
SE868-V3 Product User Guide Electrical Interface C Operation See section 9.5.1 Primary Port Configuration to specify I C interface for the primary port. The secondary port is configured by loading the appropriate FW. Upon power up, the module acts as a master transmitter and a slave receiver (multi-master mode). -
Page 45: Rf Interface
No DC voltage can be applied to the RF input. The RF-IN pin is ESD sensitive. The SE868-V3 contains an integrated LNA and pre-select SAW filter. This allows the module to work well with a passive GNSS antenna. If the antenna cannot be located near the module, then an active antenna (that is, an antenna with a built in low noise amplifier) should be used. -
Page 46: Rf Front End Design
SE868-V3 Product User Guide RF Front End Design 10. RF FRONT END DESIGN RF Signal Requirements The receiver can achieve Cold Start acquisition with a signal level above the specified minimum at its input. This means that it can acquire and track visible satellites, download the necessary ephemeris data and compute the location within a 5 minute period. -
Page 47: Gnss Antenna Polarization
SE868-V3 Product User Guide RF Front End Design For example, in a vehicular application, the GNSS antenna may be placed on the dashboard or rear package tray of an automobile. The metal roof of the vehicle will cause significant blockage, plus any thermal coating applied to the vehicle glass can attenuate the GNSS signal by as much as 15 dB. -
Page 48: System Noise Floor
SE868-V3 Product User Guide RF Front End Design on a reference ground plane (usually 50 mm by 50 mm) may give an antenna gain at zenith of 2 dBic. An antenna vendor should specify a nominal antenna gain (usually at zenith, or directly overhead) and antenna pattern curves specifying gain as a function of elevation, and gain at a fixed elevation as a function of azimuth. -
Page 49: Rf Trace Losses
Implications of the Pre-Select SAW Filter The SE868-V3 modules include a pre-select SAW filter in front of the internal LNA. Thus, the RF input of the module is connected directly to the SAW filter. Any circuit connected to the RF input pin would see a complex impedance presented by the SAW filter (especially out of band), rather than the relatively broad and flat return loss presented by an LNA. -
Page 50: Shielding
SE868-V3 Product User Guide RF Front End Design Atom processor clocked at 1.6 GHz. This is only 25 MHz away from the GNSS signal, and depending upon temperature of the SAW filter, can be within its passband. Because of the nature of the address and data lines, this would be broadband digital noise at a relatively high level. -
