New Clocking Family Offers System Flexibility,
Lower Cost, and Easier System Design
CS2000 Features
• High-performance analog/digital phase
locked loop
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 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.
• Clock multiplier/jitter reduction
• Generates a low-jitter 6 – 75 MHz output
clock from a jittery or intermittent 50 Hz
to 30 MHz clock source
• Clock generation/frequency synthesis
• Generates a low-jitter 6 – 75 MHz clock
relative to 8 – 75 MHz reference clock
• Highly accurate PLL multiplication factor
• Less than 1 PPM error
• Flexible control options
• One-time-programmable configuration
for hardware mode
• I2C® /SPI™ control port
Applications
• Configurable auxiliary output
• Buffered reference clock
• PLL Lock indication
• Second PLL output
• Buffered version of CLK_IN
• Audio/Video Receivers
• Digital Mixing Consoles
• Outboard A/D and D/A converters
• Digital Effects Processors
• Camcorders
The members of the CS2000 product
family are differentiated by the method
of control and/or a hardware mode
configuration. The CS2000-CP is
• Flexible sourcing of reference clock
• External oscillator or clock source
• Supports inexpensive local crystal
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.
• Satellite Radio Systems
• 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
