DESCRIPTION

The CDCM6208 is a highly versatile, low jitter low power frequency synthesizer which can generate 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 feature a low frequency crystal or CML, LVPECL,

LVDS, or LVCMOS signals for a variety of wireless infrastructure baseband, wireline data communication,

computing, low power medical imaging and portable test and measurement applications. The CDCM6208 also

features an innovative fractional divider architecture for four of its outputs that can generate any frequency with

better than 1ppm frequency accuracy. The CDCM6208 can be easily configured through I2C 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-programmed configurations using control pins.
