CS2500 Datasheet | Cirrus Logic

Features - I²C/SPI control port - 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) - Configurable auxiliary clock/status output - Minimal board space required - No external analog loop-filter ponents - Pin-to-pin, register map, and control patible with CS2000 and CS2200 - Single-supply operation at 1.8 V or 3.3 V Applications - Flexible timing reference source - External clock or external crystal - High resolution PLL ratio (1 PPM) - 40 ps RMS period jitter - Glitchless clock output generated from intermittent input - Automotive audio systems - Digital audio systems - Network and USB audio interfaces - Io T sensor and transducer systems - Embedded systems XTAL_ IN/REF_CLK_ IN XTAL_ OUT Divi der XTAL Inte rface CLK_IN Hyb rid PLL Core Fractio nal-N Ana log PLL Ratio (N) Fractio nal-N Digital FLL Timing ref erence Frequency reference CLK _OUT Unlock indicator I2C/S PI Control Port VDD GND CLK_O UT AUX_O UT I2C_ADDR/SPI_CS I2C_SCL/S PI_SCK I2C_SDA/S PI_SDI Advanced Product Information This document contains information for a product under development.
