3 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,
Small Cells, 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.
