No pin-compatible second source is documented, but the 6-SMD no-lead footprint (5.00mm x 3.20mm) is a standard MEMS oscillator land pattern shared by other DSC1121 frequency variants.","metaTitle":"DSC1121BM1-050.0000 MEMS Oscillator","metaDescription":"Microchip DSC1121BM1-050.0000 XO (Standard) MEMS oscillator, 50 MHz CMOS output, ±50 ppm stability, -55°C to 125°C, AEC-Q100 qualified.
