A single oscillator replaces two quartz cans on the bill of materials. Typical current draw is 3 mA max, keeping the thermal load low in the 4-VDFN package. The MEMS resonator itself draws negligible current compared to the output buffer, so the supply current is dominated by the CMOS load being driven. For a 24.576 MHz clock, ±25 ppm translates to a maximum frequency error of about 614 Hz — well within the pull-in range of a typical audio PLL. ## MEMS reliability vs quartz — the sourcing angle For a BOM line locked to this dual-frequency output pair, the only sourcing channel is independent distribution holding new-old-stock or surplus inventory. No pin-compatible direct successor is recorded in the Microchip DSC61XX family; a replacement would require requalifying a different order code or a board spin.","metaTitle":"DSC6121CE2A-0081 MEMS XO, 22.5792/24.576MHz, CMOS, Obsolete","metaDescription":"Microchip DSC6121CE2A-0081 MEMS XO, dual-output 22.5792MHz & 24.576MHz, CMOS, ±25ppm, 1.71V-3.63V, 4-VDFN.
