CDCM6208 - 2:8 Ultra Low Power, Low Jitter Clock Generator

The CDCM6208 is a highly versatile, low jitter low power frequency synthesizer which cangenerate eight low jitter clock outputs, selectable between LVPECL-like high-swing CML,normal-swing CML, LVDS-like low-power CML, HCSL, or LVCMOS, from one of two inputs that can featurea low frequency crystal or CML, LVPECL, LVDS, or LVCMOS signals for a variety of wirelessinfrastructure baseband, Small Cells, wireline data communication, computing, low power medicalimaging and portable test and measurement applications. The CDCM6208 also features an innovativefractional divider architecture for four of its outputs that can generate any frequency with betterthan 1ppm frequency accuracy. The CDCM6208 can be easily configured throughI²C or SPI programming interface and in the absence of serial interface,pin mode is also available that can set the device in 1 of 32 distinct pre-programmedconfigurations using control pins.
