GPS receiver A1082-A 7 Mounting This chapter covers the mounting of the A1082-A. 7.1 Proposed Footprint for Soldering The following proposal of a footprint for soldering is assuming a stencil thickness of 150µm. marks the center of the through holes.
Vias to GND Layer BGA Solder pads Figure 10: Antenna connector strip line A1082-A In order to gain the impedance of 50Ω, the width of the strip line needs to be calcu- lated. It depends on the thickness or height of the PCB layer (both parameters are shown in following drawing).
• High Temperature Operating Life +85°C • Vibration Variable Frequency • Mechanical Shock Please contact Tyco Electronics for detailed information. 9.3 Production Test Each module is electrically tested prior to packing and shipping to ensure state of the art GPS receiver performance and accuracy.
For demonstration and easy evaluation of GPS performance Tyco Electronics offers a Demonstration Kit (including one GPS A1082-A module). It contains a USB inter- face with according drivers to connect easily to a PC. The USB interface is an ex- tension of the serial port 0, therefore sending NMEA sentences and accepting commands.
GPS satellites. While the current date and time is transmitted in NMEA sentences, an exact and accurate timing signal is provided via the 1PPS pin of the A1082-A modules. 10.3 Standby PIN (P1.5) The Standby pin is an input pin and high active.
This manual was created with due diligence. We hope that it will be helpful to the user to get the most out of the GPS module. Anyway, inputs about errors or mistakable verbalizations and comments or propos- als to TYCO Electronics, Power Systems in Munich, Germany, for further improve- ments are highly appreciated.
