CS2501
CS2501 is Fractional-N Clock Multiplier manufactured by Cirrus Logic.
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 ponents
- Pin-to-pin, register map, and control patible 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...
