MEMS also typically ships with shorter lead times than quartz equivalents because the resonator is fabricated on a standard CMOS line rather than a quartz blank process. At 125 MHz, a quartz fundamental-mode crystal would require a third-overtone design or a PLL multiplier; the MEMS resonator generates this frequency directly, keeping the phase noise profile cleaner at the output. ## Package and footprint — 4-VLGA Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, this oscillator fits tight PCB layouts common in compact Ethernet switches, industrial sensors, and portable instrumentation.","metaTitle":"DSC1522JL3A-125M0000T MEMS Oscillator","metaDescription":"Microchip DSC1522JL3A-125M0000T MEMS XO, 125 MHz, LVCMOS, ±20 ppm stability, 2.5V-3.3V supply, -40°C to 105°C.
