CS2600
CS2600 is Fractional-N Clock Synthesizer and Clock Multiplier manufactured by Cirrus Logic.
Features
- Clock frequency synthesizer incorporating delta-sigma fractional-N analog PLL
- Generates low-jitter 6- 75 MHz clock (CLK_OUT) from 8- 75 MHz timing reference (REF_CLK_IN)
- Fractional clock multiplier and jitter reduction using hybrid analog/digital PLL
- Generates low-jitter 6- 75 MHz clock (CLK_OUT), synchronized to a 50 Hz- 30 MHz low-quality or intermittent frequency reference (CLK_IN)
- Flexible timing reference source
- External clock, external crystal, or built-in oscillator
- High resolution PLL ratio (1 PPM)
- Automatic rate control (ARC) for digital audio applications
- Seamless transitions through changes in CLK_IN frequency reference
- Customer-programmable startup configuration, using integrated one-time programmable (OTP) memory
- Hardware and software control modes
- I²C/SPI control port
- Hardware control with no host processor required
- Configurable auxiliary clock/status output
- Minimal board space required
- No external analog loop-filter ponents
- Single-supply operation at 1.8 V or 3.3 V
- 40 ps RMS period jitter (external timing reference), 35 ps RMS period jitter (oscillator reference)
- Glitchless clock output generated from intermittent input
- BCLK and FSYNC outputs (derived from CLK_OUT) for digital audio applications
- Phase alignment with CLK_IN frequency reference
Applications
- Automotive audio systems
- Digital audio systems
- Network and USB audio interfaces
- Io T sensor and transducer systems
- Embedded systems
