8N3Q001FG-0052CDI8 Programmable Timers and Oscillators

Clock/Timing – Programmable Timers and Oscillators offer precision timing application fields, such as communication, medical and testing applications. The 8N3Q001FG-0052CDI8 is a high performance programmable timer/oscillator deemed suitable for many situations, featuring a re-programmable 8:1 divided clock and integrated logic blocks. It is a highly flexible solution for many timing applications.

Operation and Usage

The 8N3Q001FG-0052CDI8 accurately maintains long-term accuracy in the range of -40 to +85 degrees Celsius. Its dual digital CMOS design offers lowpower, lowjitter operation. In addition, frequency stability over temperature ranges can be tailored using a wide selection of pre-defined temperature coefficients. The device can be programmed to divide a reference clock frequency (reference clocks ranging from 6 – 50MHz are supported) to generate a wide range of output frequencies.

The device provides two user-programmable divide ratios: 10:1 and 8:1. The default ratio of 10:1 is selected on power-up and can be changed by the user on the fly. The 8:1 ratio is used to achieve a wider frequency range than the 10:1 ratio. In addition, the device provides ON/OFF logic control via the ON/OFF control pin to enable programs to enable or disable their operations. The ON/OFF control can also be used to enable or disable individual outputs for further flexibility.

Maximum Frequency/Pulse Interval

The 8N3Q001FG-0052CDI8 is capable of generating up to 1GHz maximum frequency or providing pulse interval range of 4ns minimum to 500ms maximum. The clock frequency is adjustable in 0.1% increments over a temperature range of -40 to +85 degrees Celsius. The accuracy of its programmable frequency may be further enhanced when the clock is thermally compensated with a higher degree of accurac

Output Types

The 8N3Q001FG-0052CDI8 provides three different output types: static, programmable and CVL. Static outputs produce harmonic-free sinusoidal waveforms, while programmable outputs provide a wide range of adjustable frequencies when used in conjunction with the integrated logic blocks. The CVL outputs allow a wide range of timing options, including single-cycle, multi-cycle and pulse-width modulation.

Integrated Logic Blocks

The 8N3Q001FG-0052CDI8 includes several integrated logic blocks that allow for adaptive control of its outputs. These logic* blocks include: NAND/XOR logic for combining/gating logic, down-counter for frequency division, adjustable Pulse Width Modulation for modulating output waveforms, multiple-outputs for generating multiple combinations of output waveforms, and an async latch for creating adjustable pulse width using the integrated latch function. All of these functions are supported by an adjustable period from 2ns to 500ms.

Potential Applications

The 8N3Q001FG-0052CDI8 is suitable for a wide range of applications including: Medical: Heart rate monitors, ECG monitors, Radiation ultrasound; Communication: Wireless communication timing/error correction, Phase Locked Loops; Testing: Automated test equipment, Signal generators, and many others. The internal logic blocks allow for the generation of flexible waveform of varying pulse widths and intervals.

Conclusion

The 8N3Q001FG-0052CDI8 is a well-designed programmable timer/oscillator that can be adapted to a wide range of applications. Its adjustable period, support for multiple output types for custom waveforms as well as its logic block for dynamic waveform control make it a completely flexible solution for timing and control applications. Its thermal stability and low power consumption make 8N3Q001FG-0052CDI8 the perfect choice for applications that require a high degree of accuracy and performance.
