mosaic-X5 GNSS Module
2.1
Overview
Septentrio mosaic-X5 is a low-power multi-band multi-constellation GNSS receiver
packaged in a 31x31mm LGA module. The internal block diagram is shown below.
The module operates from a single 3V3 power supply (VDD_3V3).
The antenna connects directly to the ANT pin without need for additional components. A
3V to 5.5V DC voltage can be applied to the antenna from the VANT pin. The bias control
circuit detects overcurrent conditions (>150mA) and protects the module in case of short
circuit. See section 3.2.
The module can use its internal TCXO as frequency reference, but also accepts an external
frequency reference on the REF_I pin. See section 3.7.
Two event timer pins and a PPS output are available (1.8V LVTTL). See section 3.8.
The module features a rich set of communication interfaces:
•
Four serial ports (3.3V LVTTL), three of them with hardware flow control. See
section 3.3.
•
USB. See section 3.4.
•
Ethernet (the PHY is external to the module). See section 3.5.
