The CDCS502 is a spread spectrum capable, fundamental mode crystal oscillator with selectable frequency multiplication.
It features an advanced gain controlled fundamental mode crystal oscillator stage with a built-in load capacitance of 10pF. This oscillator stage accepts crystals from 8MHz to 32MHz with an ESR of up to 180Ω. The stage can be used with crystals with power dissipation of 50µW and up.
The input signal is processed by a PLL, whose output frequency is either equal to the input frequency or multiplied by the factor of 4.
The PLL is also able to spread the clock signal by ±0%, ±0.5%, ±1% or ±2% centered around the output clock frequency with an triangular modulation.
By this, the device can generate output frequencies between 8MHz and 108MHz with or without SSC from a fundamental mode crystal.
In x1 Mode with an SSC amount of 0%, the device works as a standard crystal oscillator and does not make use of the built in PLL.
The CDCS502 operates in 3.3V environment.
It is characterized for operation from -40°C to 85°C. It is offered in an 8 Pin TSSOP package.
