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.
