Minimal board space required
No external analog loop-filter
components required
Packaged in a 10-pin MSOP
CS2300 has internal LCO for reference clock
CS2200 is a subset and consists
of clock generation
CS2100 is a subset and consists
of clock multiplication
Featuring both a clock generator and
clock multiplier/jitter reduced clock
frequency synthesizer (clean up), Cirrus
Logic’s CS2000 is a strong entrant into
the clocking IC market. Based on a
unique hybrid analog-to-digital phase
lock loop, the CS2000 gives system
designers a unique solution for solving the
complex challenges of clock generation
and multiplication/jitter reduction.
The members of the CS2000 product
family are differentiated by the method
of control and/or a hardware mode
configuration. The CS2000-CP is
controlled via an I2C / SPI control port
and supports the full functionality of the
CS2000. The CS2000-OTP is controlled in
hardware mode via three mode pins. The
functionality of the eight selectable modes
is user defined and configured via the
one-time-programmable feature.
The CS2xxx is a growing family of
products based on the CS2000-OTP
and configured by Cirrus Logic to
support common system requirements.
Please contact Cirrus Logic for factory
configuration of the CS2000-OTP to
support your unique requirements.
