Deliverables

4	GDSII and LVS Spice netlist, behavioral, synthesis, and 
LEF models, and extensive user documentation.

4	Integration support to ensure 
a successful tape out (included 
in standard design license fee).

Spread Spectrum PLL

Features

4	Designed for PC, networking, and consumer-electronics applications where spread-spectrum clock sources are required to satisfy FCC requirements for peak RF spectral emissions.

4	Spreading rate and spreading depth are precisely adjustable to allow the designer to dial-in the desired characteristics.

4	14-bit fractional-N feedback divider with 3 bits of precise control.

4	Available with multi-phase outputs.
