IDT, Integrated Device Technology Inc 840N202CKI-000LF

Description
The ICS840N2021 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 can generate any output frequency in the 1MHz - 250MHz range. 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.
