Description
The 849N212I is a highly flexible FemtoClock NG general purpose, low phase noise Universal Frequency Translator / Synthesizer with alarm and monitoring function suitable for networking and communications applications. The 849N212I has three operating modes to support a very broad spectrum of applications: frequency Synthesizer, high-bandwidth frequency translator, and low-bandwidth frequency translator. This device provides two factory-programmed default power-up configurations burned into One-Time Programmable (OTP) memory. To implement other configurations, these power-up default settings can be overwritten after power-up using the I2C interface and the device can be completely reconfigured.
