This is not a last-time-buy with a fixed window — the part is no longer manufactured and must be sourced through independent surplus or broker channels. ## Parametric fit and temperature grade For a 20 MHz clock, ±25 ppm translates to a maximum drift of ±500 Hz — tight enough for UART bit-rate accuracy and general-purpose microcontroller timing, but not for precision RF or Ethernet reference clocks. At 1.71 V the core draws roughly 2.2 mW; at 3.63 V it is about 4.7 mW. This low-power profile suits battery-powered or thermally constrained designs where a quartz oscillator would consume 3–5× the current. The 0.90 mm profile fits under shielding cans or in slim enclosures where a 1.2 mm+ crystal oscillator package would not clear.","metaTitle":"Microchip DSC6021CI2A-009ST MEMS XO, 20MHz/25MHz, CMOS","metaDescription":"Microchip DSC6021CI2A-009ST MEMS XO, 20MHz & 25MHz outputs, CMOS, 1.71V-3.63V, ±25ppm, -40°C to 85°C.
