Crystal Oscillator for a 32 kHz Crystal - GLOBALFOUNDRIES® 22FDX®

ri_xtalosc_gf22fdx_32k is a crystal oscillator designed to work with 32 kHz crystals. It is layouted as an IO combo-padcell compatible with Racyics 1.8 V EG IO Library. It supports autonomous startup and continues running even when the core supply is off. Automatic gain control ensures fast and reliable startup, while configurable load support and a bypass mode provide flexible integration for low-power timing applications. It is typically used in systems requiring a 32 kHz crystal for low-power timing functions.
