Time pulse
u-blox receivers include a time pulse function that provides pulses with a
configurable
pulse period,
pulse length and polarity (rising or falling edge). The u-
center 2 evaluation tool can be used to configure
the time pulse parameters. The time pulse signal is available at the buffered 50
Ω
SMA connector and
the 14-pin connector. In addition, the time pulse signal is inverted and connected to the LED on the
front side of the EVK.
The TP1(J3) SMA connector for the co-ax 1PPS output has a buffered output with configurable drive
strength to ensure the time pulse shape and rise time is optimal into various loads. By default, it has
no jumper on J2. A jumper can be placed to bypass a resistor to increase the drive strength into low
impedance loads.
Open the evaluation kit to access the J2 jumper.
