GENERAL DESCRIPTION

The ICS813001I is a dual VCXO + FemtoClock? Multiplier designed for use in Discrete PLL loops. Two selectable external VCXO crystals allow the device to be used in multi-rate applications, where a given line card can be switched, for example, between 1Gb Ethernet (125MHz system reference clock) and 1Gb Fibre Channel (106.25MHz system reference clock) modes. Of course, a multitude of other applications are also possible such as switching between 74.25MHz and 74.175824MHz for HDTV, switching between SONET, FEC and non FEC rates, etc.
