ICS844022I-02 Overview
The ICS844022I-02 is an Ethernet Clock Generator and a member of the HiPerClocksTM HiPerClockS™ family of high performance devices from ICS. The ICS844022I-02 uses an 18pF parallel resonant crystal over the range of 24.5MHz - 34MHz. For Ethernet applications, a 25MHz crystal is used and either 62.5MHz or 125MHz may be selected with the FREQ_SEL pin.
