The 840N202I is a highly flexible FemtoClock® NG general purpose, low phase noise Frequency Translator / Synthesizer with alarm and monitoring functions suitable for networking and communications applications. It is able to generate any output frequency in the 1MHz - 250MHz range (see Table 3 for details). A wide range of input reference clocks and a range of low- cost fundamental mode crystal frequencies may be used as the source for the output frequency. The 840N202I has three operating modes to support a very broad spectrum of applications: Frequency Synthesizer , High-Bandwidth Frequency Translator and a 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 IDT during the final test phase from an on-hand stock of blank devices. The two configurations may be completely independent of one another.
