Compact GPS Module with Advanced
Noise Resistance Providing High Sensitivity
and Low Power Consumption
CXD5400
The CXD5400 is a GPS*1 and SBAS*2 signal receiver module capable of high performance navigation in the most
demanding applications. This module incorporates all the components except the antenna required for GPS reception (GPS receiver IC, TCXO*3,
SAW filter, RTC*4 crystal oscillator and other components) and requires no additional external elements or components
for operation other than a power supply.

Low Power Module that Can be
Used for Various Applications
The power consumption of a GPS receiver
is seriously impacted by the strength of the
satellite signal. The CXD5400 provides
several intermittent operation modes that
enable autonomous control of the receiver
and lower power consumption. Combined
with an acceleration sensor, the module can
detect device status to further reduce power
consumption.
Compact and Easily Installed
Module
The CXD5400 incorporates all circuits and
elements except an antenna (GPS receiver IC,
LNA and SAW filters and other RF circuits,
LDO capacitors, inductors, etc.). The circuit
configuration has been designed to maximize
performance of the chip mounted in the GPS
receiver IC and facilitate design of peripheral
circuits.
Noise Rejection and Monitoring
Function
Equipped with a noise rejection filter, the
CXD5400 can remove noise at the GPS
frequency (1.57542 GHz) region in realtime.
The module also provides a function
for real-time monitoring of external noise
or noise from the cellular equipment is
integrated into to easily evaluate the device
during integration. Since no special device is
required for measurement, product operation
status can be monitored without having to
disassemble it.
Records Tracks Showing Where
the GPS Has Been
Positioning results can be recorded in internal memory on the CXD5400. When combined
with intermittent operation, the module
consumes less power and uses less memory
per unit of time enabling extended recording
time.
Single Power Supply Operation
The CXD5400 can be operated on a single
power supply with built-in LDO and DC-DC
converters. By connecting the module
directly to a product's battery will enable
operation independent of the system allowing
recording of positional results regardless of
power supply status of the products.

To develop a user-friendly GPS
module not only for the end user but
also for designers, we provided it with
advanced basic functions, ease of
installation, noise resistant performance,
single power supply operation and
other functions. GPS has become an
indispensable mobile device function and
we are convinced that the CXD5400 is
an ideal solution for such devices. The
CXD5400 is your best choice for any
GPS application.
