Description
The 8T49N203I 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 8T49N203I 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. The two configurations are specified by the customer and are programmed by Renesas during the final test phase from an on-hand stock of blank devices.
