Introduction

Programmable oscillators are a type of electronic device which can be programmed to produce a set frequency, which can then be adjusted or modified over time to meet the specific requirements of the application being used. The SG-8018CA-TJHSC is one such device, designed for the purpose of providing custom frequency output from a single package. It is part of a family of programmable oscillators, which generally provide excellent reliability and accuracy in meeting their required performance specification.

Overview of SG-8018CA-TJHSC

The SG-8018CA-TJHSC is a programmable oscillator which is designed for high-performance applications. It is a SMD (surface mount device), and incorporates a 3-wire serial interface, allowing for reprogrammability of frequency and other output settings. The frequency range of the oscillator is from 6.144 to 48.768 MHz, with an accuracy of ±30 ppm over ±50 ppm temperature range. The power consumption of the device is typically 3.3 Vdc at 4 ns rise time and 2.5 Vdc at 4 ns fall time. The operating temperature range is from -40C to +85C, and the device is RoHS compliant.

Application Field and Working Principle

The SG-8018CA-TJHSC has a wide range of applications, some of which include audio applications, sensor applications, automotive applications, communication systems, portable devices, RFID reader applications and more. It is particularly useful for applications requiring frequency synthesis and reprogrammability. The working principle of the SG-8018CA-TJHSC is based on an asynchronous frequency synthesizer. The frequency of the output is determined by the clock frequency and the ratio of the Programmable Divider Register (PDR). The PDR is programmed with an 8-bit word and is used to divide the clock frequency by a programmable ratio. The device also incorporates a clock buffer, which is used to provide stable output frequencies.

Conclusion

The SG-8018CA-TJHSC is a versatile programmable oscillator suitable for many applications. It offers excellent reliability, accuracy and power efficiency, making it an ideal choice for demanding applications. With its wide frequency range, programmable divider register, and clock buffer, it is perfect for applications requiring frequency synthesis and reprogrammability.
