Programmable timers and oscillators come in many shapes and sizes and fulfill a variety of applications. A great example is 8N3DV85KC-0147CDI8, which is a maximum precision oscillator. It offers a low profile, ultra-small footprint in an industry-standard 8-pad or 3.2mm flat-pack ceramic package.

Applications

This programmable oscillator is designed for use in a wide variety of applications including telecom, broadcast, and electronics industries. For example, it can be used for phase-locked loop generation, reference clock generation and time delay networks. Additionally, it can complement logging data on consumer electronics. Few of its other applications include general instrumentation, VCA recovery and as an input reference for D/A conversion.

8N3DV85KC-0147CDI8 can be used as a timebase in consumer and pro audio mixers, studio routers, and up/down converters. It is also employed in many RF applications, such as digital tuners, frequency synthesizers, land mobile radios and set top box receivers. Furthermore, it is used in the production of advanced portable or desktop devices.

Working Principle

This ultra-precision leadless ceramic oscillator utilizes a dual-frequency signal generated by two different oscillators to achieve cycle-to-cycle stability and frequency accuracy. This is achieved by multiplying and dividing the two signal frequencies that are synthesized in an analog divider chain. The frequency accuracy is then improved using a temperature compensation. The temperature compensation implemented in this oscillator reduces the temperature-induced frequency variation without any external temperature sensors.

8N3DV85KC-0147CDI8 is designed to operate with a supply voltage range of 3.3 to 3.6V. This feature makes it suitable for low voltage, energy-saving applications. The oscillator offers typical output frequencies of 10MHz to 50MHz, which can be precisely tuned using the external control port. The same control port offers flexibility in adjusting the frequency accuracy and stability of the oscillator.

Features and Benefits

One of the main advantages of 8N3DV85KC-0147CDI8 is its extremely small size. Its flat package is only 3.2mm x 3.2mm and it provides a very low profile. This makes it ideal for tight spaces, reducing the space requirements of the product in question. Furthermore, it requires no power calibration, as the signal is locked in by the frequency-adapting scheme.

Its maximum frequency accuracy is 0.1 ppm, providing ultra-precision performance. Additionally, its frequency offset drift from 25°C to 85°C is typically 0.17 ppm, and its cycle-to-cycle jitter is typically 20 ps. 8N3DV85KC-0147CDI8 also provides fast transient response and excellent phase noise performance, which makes it a suitable choice for various high-end applications.

Conclusion

8N3DV85KC-0147CDI8 is a precision oscillator designed for a variety of applications. It offers an ultra-small footprint and a low-profile package, making it ideal for tight spaces. It also provides excellent frequency accuracy and a wide range of frequency capabilities. Additionally, it offers stable frequency and low temperature drift, providing excellent reliability and performance. All of these features make it a great option for many demanding applications.
