No official successor or second-source is listed in the product record. A board spin is required for any functional replacement. ## Dual-output clock — 50 MHz and 100 MHz from one package The dual-output architecture saves a second oscillator footprint and routing layer on dense PCBs — useful when a processor core clock and a peripheral bus clock must run from synchronized references. ## ±25 ppm stability across industrial temperature This covers most industrial Ethernet, CAN, and USB timing budgets without external temperature compensation. Typical supply current is 3 mA max, keeping the thermal load low in the VLGA package. ## MEMS resonator — no quartz, no crystal aging drift The oscillator is factory-trimmed and ready to place. The 4-VLGA package (0.50 mm pitch, exposed pad) reflows on a standard lead-free profile.","metaTitle":"Microchip DSC6121JI2A-00AH MEMS XO, 50MHz & 100MHz","metaDescription":"Microchip DSC6121JI2A-00AH MEMS XO, dual-output 50MHz & 100MHz CMOS, ±25ppm, -40°C~85°C, 4-VLGA.
