Description
The 8T49N105I is a highly flexible FemtoClock® NG general-purpose, low-phase noise Universal Frequency Translator (UFT)/Synthesizer with alarm and monitoring functions suitable for networking and communications applications. It can generate any output frequency in the 0.98MHz to 312.5MHz range and most output frequencies in the 312.5MHz to 1,300MHz range.
The device has three operating modes to support a very broad spectrum of applications: Frequency Synthesizer, High-Bandwidth Frequency Translator, or Low-Bandwidth Frequency Translator. This device provides two factory-programmed default power-up configurations burned into One-Time Programmable (OTP) memory. The configuration to be used is selected by the CONFIG pin. 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. The two configurations may be completely independent of one another. 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. However, these settings would need to be rewritten the next time the device powers up.
