SL869x-V2 Family Product User Guide Product Description 2. PRODUCT DESCRIPTION The SL869-V2 family of GNSS receiver modules provides complete position, velocity, and time (PVT) engines featuring high performance, high sensitivity, and low power consumption. All modules compute a navigation solution using GPS signals. Multi-constellation modules add GLONASS, BeiDou, and Galileo signals to yield better coverage, greater accuracy, and improved availability.

SL869x-V2 Family Product User Guide Product Features PRODUCT FEATURES Multi-Constellation Navigation (SL869-V2 and SL869L-V2 only) GPS and GLONASS constellations are enabled by default. Enabling BeiDou disables GLONASS and Galileo. The user may enable or disable constellations via the $PMTK353 command The SL869-V2S and SL869L-V2S support GPS only.
SL869x-V2 Family Product User Guide Product Features Assisted GPS (AGPS) Assisted GPS (or Aided GPS) is a method by which TTFF is improved (reduced) using information from a source other than broadcast GPS signals. The necessary ephemeris data is calculated either by the receiver itself (locally-generated ephemeris), or a server (server-generated ephemeris) and stored in the module.
SL869x-V2 Family Product User Guide Product Features Static Navigation Static Navigation is an operating mode in which the receiver will freeze the position fix when the speed falls below a set threshold (indicating that the receiver is stationary). The course and altitude are also frozen, and the speed is reported as “0”. The navigation solution is unfrozen when the speed increases above a threshold or when the computed position exceeds a set distance (10 m) from the frozen position (indicating that the receiver is again in motion).

SL869x-V2 Family Product User Guide Product Features Power Management Modes The receiver supports operating modes that reduce overall current consumption with less frequent position fixes. Availability of GNSS signals in the operating 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.
SL869x-V2 Family Product User Guide Product Features Standby Modes In these modes the receiver stops navigation, the internal processor enters the standby state, and the current drain at main supply VCC_IN is substantially reduced. STOP: ARM baseband, RF, and TCXO are powered down SLEEP: ARM baseband and RF are powered down To enter a Standby mode, send the following command: $PMTK161,0*28...
SL869x-V2 Family Product User Guide Product Features Periodic Modes (SL869-V2 and SL869L-V2 only) Periodic Low Power modes are not available on the SL869-V2S and SL869L-V2S. These modes allow autonomous power on/off control with reduced fix rate to decrease average power consumption. The main power supply pin VCC_ON is still powered, but power distribution to internal circuits is internally controlled by the receiver.
SL869x-V2 Family Product User Guide Product Features To enter a Periodic mode, send the following NMEA command(s): $PMTK223 ,<SV>,<SNR>,<Extension threshold>,<Extension gap>*<checksum> ( Optional) Where: SV = 1 to 4, default = 1 SNR = 25 to 30, default = 28 Ext.
SL869x-V2 Family Product User Guide Data Retention 5. DATA RETENTION (SL869-V2 and SL869L-V2S modules only) The receiver is capable of retaining data elements under the various initialization types. If Vbatt is maintained, no data will be lost. The following table shows which data elements are saved under each type of initialization if both Vcc and Vbatt are removed.

SL869x-V2 Family Product User Guide Electrical Interface Antenna Related Signals 9.3.3.1. VCC-RF (Active Antenna Supply Voltage) If an active antenna or external LNA is used, an external bias-T is required to provide voltage to it. (SL869-V2 and SL869-V2S only) A DC blocking capacitor is also required to prevent out-of-range DC voltage from being applied to RF-IN except for SL869L-V2 and SL869L-V2S modules (which include a DC blocking capacitor).
SL869x-V2 Family Product User Guide Electrical Interface Control (Input) Signals 9.3.4.1. RESET-N (SL869L-V2 and SL869L-V2S only) The Reset-N input is a low true input to reset the receiver to the default starting state. This signal is not required for the module to operate properly, so this pin may be left unconnected. However, it is recommended to bring it out to a test point..
SL869x-V2 Family Product User Guide Electrical Interface The logic levels are shown in Table 9-11 Logic Levels: TX and 1PPS. Serial I/O Ports All modules include a primary UART serial port. SL869L-V2: The secondary port is I C. It can be changed to UART via $PMTK258 command Note that the module will reset when the interface is changed.

SL869x-V2 Family Product User Guide Electrical Interface Antenna RF Interface RF-IN The RF input (RF-IN) pin accepts GNSS signals in the range of 1561 MHz to 1606 MHz (1573.42 to 1577.42 MHz for the SL869-V2S) at a level between -125 dBm and -165 dBm into 50 Ohm impedance.
SL869x-V2 Family Product User Guide RF Front End Design RF FRONT END DESIGN The SL869-V2 and SL869-V2S modules contain a preselect SAW filter in front of the RF input. The SL869L-V2 and SL869L-V2S modules add an LNA in front of the (post-select) SAW filter which allows the modules to work well with passive GNSS antennas.
SL869x-V2 Family Product User Guide RF Front End Design thermal coating applied to the vehicle glass can attenuate the GNSS signal by as much as 15 dB. Again, both of these factors will affect the performance of the receiver. Multipath interference is a phenomenon where the signal from a particular satellite is reflected and is received by the GNSS antenna in addition to or in place of the line of sight signal.
SL869x-V2 Family Product User Guide RF Front End Design ground plane size and any external matching components. Failure to follow these requirements could result in very poor antenna performance. It is important to note that GNSS antenna gain is not the same as external LNA gain. Most antenna vendors will specify these numbers separately, but some combine them into a single number.
SL869x-V2 Family Product User Guide RF Front End Design RF Trace Losses RF Trace losses on a PCB are difficult to estimate without having appropriate tables or RF simulation software. A good rule of thumb would be to keep the RF traces as short as possible, make sure they Ω...
SL869x-V2 Family Product User Guide RF Front End Design Input to the Pre-select SAW Filter (SL869-V2 and SL869-V2S only) The SL869-V2 and SL869-V2S modules include a pre-select SAW filter at the RF input 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.
SL869x-V2 Family Product User Guide RF Front End Design Simulations done by Telit show the following results: Additional signal loss Inductor (dB) Murata LQG15HS27NJ02 Inductor 0.65 Quarter wave stub on FR4 0.59 Coilcraft B09TJLC Inductor (used in ref. design) 0.37 Table 10-1 Inductor Loss Since this additional loss occurs after the LNA, it is generally not significant unless the circuit is being designed to work with both active and passive antennas.
SL869x-V2 Family Product User Guide Reference Designs REFERENCE DESIGNS Figure 11-1 SL869-V2 Family Reference Design Along with power and grounds, the minimum signals required to operate the receiver properly are the RF input signal and two digital signals (TX and RX). The RF input can be connected directly to a passive GNSS antenna.

The reflow profile must not exceed the profile given IPC/JEDEC J-STD-020 Table 5-2, “Classification Reflow Profiles”. Although IPC/JEDEC J-STD-020 allows for three reflows, the assembly process for the module uses one of those profiles, therefore the module is limited to two reflows.
