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.

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.

GPS NTP Time Server - SYNTIME
Signals & Systems India Private Limited
Your product description goes hGPS NTP Time Server (SYNTIME) for Network Time Synchronization is a highly accurate time server. It generates time protocols to synchronize NTP/SNTP clients (Simple Network Time Protocol)/PTP clients (Precision time protocol IEEE 1588) over the network and operates at a speed of 10/100/1000Mbps. The NTP server accepts the time and frequency signals from sources like GPS or GLONASS. It achieves nanosecond accuracy and the system clock operates at stratum 1 when synchronized with time sources. It is a sleek, rack-mountable unit that synchronizes and maintains equipment/device time and avoiding any time drifts due to local RTCs. NTP output from time server supports unicast, broadcast, and multicast methods based on selection and behaves like a reference clock for the network. Apart from time synchronization protocols, it supports MD5 (Security key), SNMP, SSH, HTTP (Configuration), TELNET, FTP, and SYSLOG. IP address of the LAN ports can be field configurable.
