That is the leakage floor for a battery-backed RTC or a sleep-state clock tree. The package is a 4-SMD, No Lead Exposed Pad — 7.00 mm x 5.00 mm body, 0.90 mm seated height. The exposed pad underneath is the thermal and electrical ground plane; the PCB layout should tie it to the ground plane with multiple vias to keep the thermal resistance low. The 0.276\" x 0.197\" footprint is a standard 7x5 mm oscillator land pattern, shared with many quartz and MEMS oscillators.","metaTitle":"DSC1001AI5-020.0000T – Microchip MEMS Oscillator 20 MHz","metaDescription":"Microchip DSC1001AI5-020.0000T XO (Standard) 20 MHz CMOS output.
