Description
CS2600 Fractional-N Clock Synthesizer and Clock Multiplier Features Minimal board space required Frequency synthesizer based on delta-sigma fractional-N analog PLL — Generates a low-jitter 6–75 MHz clock (CLK_OUT) from 8–75 MHz timing reference clock (REF_CLK) Clock multiplier and jitter reduction based on hybrid PLL — Generates a low-jitter 6–75 MHz clock (CLK_OUT) from a jittery or intermittent 50 Hz–30 MHz input clock source (CLK_IN) Highly accurate PLL multiplication factor — No external analog loop-filter components Customer-programmable startup configuration, using integrated One-Time Programmable (OTP) memory Automatic rate control for digital audio applications BCLK and FSYNC outputs (derived from CLK_OUT) for digital audio applications can be aligned in phase with the clock source Glitchless clock outputs derived from an intermittent input clock — Less than 1 PPM I²C/SPI control port and hardware control mode Configurable auxiliary output Flexible sourcing of timing reference clock — External clock, external crystal, or built-in inductorcapacitor oscillator (LCO) Applications Digital audio systems Network and USB audio interfaces IoT sensor and transducer systems Embedded systems Period jitter of 40 psRMS for REF_CLK and 35 psRMS for Automotive audio systems LCO VDD GND XTI/ REF_CLK XTO/ LCO_EN CLK _I N Divider XTAL In t er fa ce LCO PLL Core Fractional‐N Analog PLL Ratio (N) Frac tiona l‐N Digital FLL Timing Reference F...
