Product Description
The CAN6-CT6 is a small form factor GPS mod
ule solution intended for a broad range of
Original Equipment Manufacturer (OEM) products, where fast and easy system integration
and minimal development risk is required. The user only need to provide DC power of 3.0V ~
3.6V and GPS signal; the CAN6-S will output navigation solution in standard NMEA-0183
.
Applications
The CAN6-CT6 features 48
channel GPS receiver with fast time to first fix and improved
-
148dBm cold start sensitivity. The superior cold start sensitivity allows it to acq
uire, track, and
get position fix autonomously in difficult weak signal environment. The receiver’s
-163
dBm
tracking sensitivity allows continuous position coverage in nearly all application environments.

3 1pps One-pulse-per-second (1PPS) time mark output, 3V LVTTL. The Pin
provides one pulse-per-second output , when getting 3D position
fix. The pulse duration is about 4msec at rate of 1 Hz.

20 TXD UART serial data output, 3V LVTTL. One full-duplex asynchronous
serial UART port is implemented. This UART output is normally
used for sending position, time and velocity information from the
receiver in NMEA-0183 format. When idle, this pin output HIGH.
21 RXD UART serial data input, 3V LVTTL. One full-duplex asynchronous
serial UART port is implemented. This UART input is normally for
sending commands or information to the receiver in binary
protocol. In the idle condition, this pin should be driven HIGH. If
the driving circuitry is powered independently of CAN6, ensure
that this pin is not driven to HIGH when primary power to CAN6 is
removed, or a 10K-ohm series resistor can be added to minimize
leakage current from application to the powered off module.
22 V_BCKP Backup supply voltage for internal RTC and backup SRAM, 1.8V ~
6V. V_BCKP must be applied whenever VCC is applied. This pin
should be powered continuously to minimize the startup time. If
VCC and V_BCKP are both removed, the receiver will be in factory
default mode upon power up, all user configuration set is lost. For
applications the does not care cold starting every time, this pin
can be connect to VCC.
23 VCC Main power supply, 3.0V ~ 3.6V DC
24 Gnd This is Ground pin.

PCB Layout
RF:The signal path from antenna to RF input of CAN6-CT6 is the most critical part of
application design. The goal is to provide optimal 50-ohm match between a 50-ohm antenna
and the module 50-ohm RF input for maximum power transfer. The 50-ohm grounded
coplanar wave guide, consisting of the RF input signal with RF ground on either sides and a
RF ground underneath, is a good choice for efficiency.

SMT Reflow Profile :
The reflow profile shown above should not be exceeded, since excessive temperatures or
transport times during reflow can damage the module. Cooling temperature fall rate: max 3°C /
