Clock Drivers
-
Multiple timing signals ("clocks") are required by CCDs, IR FPAs, and some CMOS image sensors to transport electrical charge across the array to a sense amplifier for conversion into image data. Pulse Instruments offers a line of "clock drivers" for generating these timing signals. The parameters of these clocks (clock rate, pulse width, pulse amplitude, rise- and fall-times, etc.) greatly influence the behavior and performance of the imaging device. Our products take logic-level inputs from a pattern generator and allow the user to adjust the output parameters to suit their device and testing requirements. Clocks can be "tweaked" in real-time to determine optimal operating parameters for a particular device, or else programmed in accordance with a test plan for automated production test.

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.

Clock and Trigger Distribution Card
-
The clock and trigger distribution card is a simple and passive component that allows to synchronize several systems externally. No programming is necessary. A clock can be fed in from an external device or as an option an internal clock oscillator can be equipped by the factory. This clock is then also used to synchronize an external trigger signal into the clock domain. Both, clock and synchronized trigger, are then fed into a maximum of 17 different systems. Each system can be a single card or a synchronized set of cards that run with an internal star-hub.

NEO-M9N, Chip Antenna (Qwiic)
-
The SparkFun NEO-M9N GPS Breakout with on-board chip antenna is a high quality GPS board with equally impressive configuration options. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations witn ~1.5 meter accuracy. This breakout supports concurrent reception of four GNSS. This maximizes position accuracy in challenging conditions, increasing precision and decreases lock time; and thanks to the onboard rechargeable 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.

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).
