Description
CS2501 Fractional-N Clock Multiplier Features I²C/SPI control port 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 Configurable auxiliary clock/status output Minimal board space required — No external analog loop-filter components Pin-to-pin, register map, and control compatible with CS2100 and CS2300 Single-supply operation at 1.8 V or 3.3 V High resolution PLL ratio (1 PPM) 40 psRMS period jitter (external timing reference), 35 psRMS period jitter (oscillator reference) Glitchless clock output generated from intermittent input Applications Automotive audio systems Digital audio systems Network and USB audio interfaces IoT sensor and transducer systems Embedded systems CS2501 XTAL_ IN/REF_CLK_ IN XTAL_ OUT Divi der XTAL Inte rface Oscillator Hyb rid PLL Core Fractio nal-N Ana log PLL Ratio (N) Timing ref erence Frequency reference CLK _OUT Unlock indicator VDD GND CLK_O UT AUX_O UT CLK_IN Fractio nal-N Digital FLL I2C/S PI Control Port 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.
