SparkFun GPS Breakout
ZOE-M8Q (Qwiic)
-
The SparkFun ZOE-M8Q GPS Breakout is a high accuracy, miniaturized, GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

Four Channel Clock Driver Card
PI-41401
-
The PI-41401 is a four channel Clock Driver card capable of operating up to 140 MHz at 3V and 100 MHz at 5V amplitudes into a 50 Ohm load. The PI-41401 has a clock rate of 90 MHz at an amplitude of 5 volts into a 1-MOhm load. Into a high impedance load the output voltage range is from –5 volts to +8 volts with the pulse amplitude ranging from 0V to 9V. When driving a 50 load the voltage range is –2.5 volts to 4.0 volts with the pulse amplitude ranging from effectively 0V to 4.5V. Each channel has a common edgespeed control to vary the rising and falling edges of the output waveform. The adjustable slew rate range, for any amplitude, is the minimum edgespeed of that amplitude times 5. The output pulse amplitude and the load being driven determine the range of variability.

Clock Synchronization
-
Analog Devices Clock synchronizers are designed for wired networking applications, providing the clock redundancy functionality needed to maximize system uptime. Our technology supports clock synchronization with common standards, including 1 pulse per second (PPS) output signal from a GPS receiver. GPS signals are broadly available and utilize an extremely stable atomic clock as its time base, but they are often noisy. Systems rely on the IEEE1588 timing protocol to establish synchronous communications across the wired network, including synchronous Ethernet and synchronous digital hierarchy (SDH) to optical transport network (OTN) mapping/demapping. The IEEE1588 protocol has emerged as the preferred method for Clock synchronizing systems throughout both computer networks and local area networks (LAN).
