The 557GI-08LF is a high performance, low power programmable timer produced by 3C solutions. It is primarily used to generate accurate timing signals in a variety of clock/timing applications, such as systems requiring synchronization between different nodes, high speed FPGA data acquisition, and communication networks. It features an integrated oscillator and a wide voltage range from 3.3V to 5V. It also offers a high temperature operating range of -40°C to 125°C and excellent stability when operated at temperatures ranging from -55°C to 150°C.

The 557GI-08LF is a versatile timer platform that can be used for several applications. It provides frequency synthesis and time event control capabilities, which enable designers to tailor the timing response of their clock/timing systems to meet specific device requirements. It has a minimum load voltage of 3V and a maximum of 5V, making it suitable for a range of different applications. Additionally, it features a wide programmable resolution of up to 0.1 µs, excellent accuracy, and high-speed processing capabilities. This makes it suitable for high-frequency applications, such as providing Fine Timing and Precision Synchronization (FTPS) in communication networks, embedded system clocks, and medical systems.

The 557GI-08LF utilizes a voltage controlled oscillator (VCO) to generate an accurate and stable clock frequency. The VCO generates a higher frequency than the desired frequency and the frequency is then divided down to the desired output frequency by a divide-by-number counter. The VCO’s output frequency is then compared with the reference frequency, allowing the output of the timer to be adjusted to maintain the desired frequency. The VCO’s frequency can be adjusted by changing the voltage applied to it, allowing designers to easily adjust the output frequency of the timer.

The 557GI-08LF also features several programmable parameters, including programmable frequency, duty cycle, and reset pulses. This allows engineers to tailor their clock/timing systems to meet specific application requirements. The duty cycle parameter enables the output of the timer to be adjusted to allow output events to occur at specified intervals, while the reset pulses provide a reset pulse to start or stop operations, as well as a reset pulse to adjust the timer’s output frequency. The programmable parameters also include several timers, allowing the time between output events to be accurately adjusted.

In addition to its timing and synchronization capabilities, the 557GI-08LF also provides protection against destructive power surges, over-temperature conditions, and under-voltage conditions. This makes the 557GI-08LF a reliable and durable timer solution, suitable for a range of applications. Its low power consumption, wide temperature range, and accurate output make it an ideal solution for clock/timing-related applications, such as medical systems, communication networks, embedded system clocks, and FPGA data acquisition.
