The 3.3V 100MHz Oscillators library includes a programmable oscillator macro I/O cell.
▪ 100 MHz programmable oscillator
These libraries are offered at both 16nm and a 12nm shrink. They
are available in a staggered CUP wire bond implementation with a flip chip option.
To utilize these cells in the pad ring, an additional library is required – 3.3V Support: Power. That library contains the DVDD/DVSS power cells necessary for ESD protection, the POC and VREF cells, and a rail splitter to isolate the oscillator in its own power domain as recommended. It also contains an input-only buffer, isolated analog I/O, and a full complement of power cells along with corner and spacer cells to assemble a complete pad ring by abutment. The rail splitter allows multiple power domains to be isolated in the same pad ring while maintaining continuous VDD/VSS for robust ESD protection.
