Additional Details

The ICS8533AG-11LF features a fully integrated phase-locked loop (PLL) and voltage-controlled oscillator (VCO). It uses a fractional divider to generate a wide range of output frequencies from a reference clock. The device supports both crystal oscillator and external clock inputs, providing flexibility in clock source selection. The LVDS output drivers provide low skew and low jitter clock signals for driving high-speed data transmission lines. The device operates from a 3.3V supply voltage and is available in a space-saving 20-TSSOP package.

The low additive phase jitter performance of the ICS8533AG-11LF makes it ideal for applications where minimizing jitter is critical, such as in high-speed networking and telecommunications equipment. The integrated VCO and PLL simplify clock tree design, reducing the number of components required and lowering system cost. The output enable control allows for precise control over the clock output, enabling power saving and system testability.
