Page 6: Introduction
1 Introduction A5135-H is an antenna module with SiRFstarV Flash based chip and an on-board patch antenna (15mm x 15mm x 4mm). RF switch was implemented so as to sup- port external active antenna for performance enhancement if required. In order to have an easier migration for existing customers using A2235-H, we decided to keep same pin assignment as that of A2235-H. -

RS232 interface based on the GPS+GLONASS module A5135-H. Figure 5: Minimum configuration A5135-H NOTE: It is recommended to supply Vcc continuously! Use SiRFaware other low power modes to reduce power consumption of the module while no position information is required. - Page 16 Remarks: • Place C1 to C5 (here: 0.1µF) close to MAX3232. For capacity values see datasheet of actual component used. • Use 3.3V level shifter (MAX3232 or equivalent). V1.0 - Dec-16 User’s Manual Page 16 of 38...

Page 26: Mounting
7 Mounting This chapter describes the suggested mounting process for the A5135-H GPS+GLONASS receiver modules. In a RoHS compliant product with a RoHS compliant process it is recommended to use chemical tin as the counter-part to the module’s pins. This will guarantee highest resistance against shocks. - Page 27 Figure 12: Proposal (1) of the PCB design 2. If proposal 1 is not allowed. Placed a round Copper keep out region (diameter ≥3mm) on the application PCB underneath the RF feed-point to alleviate the inter- ference from RF signal to other part of circuitries. Besides, ground vias (says, 8) should be placed surrounding the through hole for further shielding purpose.

Page 28: Recommended Profile For Reflow Soldering
Time 25°C to peak temperature 8 minutes max. Table 8: Reflow soldering profile A5135-H As results of soldering may vary among different soldering systems and types of solder and depend on additional factors like density and types of components on board, the values above should be considered as a starting point for further optimi- zation. -
Page 29: Use Of External Antenna
A major rule is to keep the strip line as short as possible. Addition- ally, Strip line needs a good reference ground. Figure 14: Antenna connector strip line A5135-H In order to achieve the impedance of 50 Ω, the width of the strip line needs to be calculated. -

GPS+GLONASS satellites. While the current date and time is transmitted in NMEA sentences (UTC), an exact and ac- curate timing signal is provided via the 1PPS pin of the A5135-H GPS+GLONASS receiver. -
Page 34: Hz Navigation Update Rate
The NMEA messages containing absolute timing information (UTC time) are pro- vided around 300ms after the 1PPS signal typically. This may change with the GPS+GLONASS receiver setup. The 1PPS signal is provided on a “as is” basis with no accuracy specification. It’s NOT recommended to use 1PPS signal for accurate timing application. -
