MEMS oscillator for extreme-temperature timing
The DSC1101CM1-032.0000 is a Microchip MEMS-based XO (Standard) oscillator delivering a 32 MHz CMOS clock from a 2.25V to 3.6V supply rail. The MEMS resonator replaces the quartz blank — no crystal to crack under 50 g shock, no startup hesitation at -40°C. The 6-SMD no-lead package (3.20 mm x 2.50 mm) keeps the footprint small enough for dense PCB layouts.
Standby function and power budget
A dedicated Standby (Power Down) pin pulls the output to high-impedance and drops supply current to 95 µA max. For a battery-powered sensor node that sleeps 99% of the time, the oscillator's own draw during standby adds negligible drain — the node stays in the field longer between battery swaps. Active current is 35 mA max at full 32 MHz toggle — typical for a CMOS-output oscillator at this frequency. The ±50 ppm frequency stability holds the clock edge jitter within tight margins for the downstream MCU or FPGA PLL.
Listed as Active by Microchip — no NRND flag, no last-time-buy deadline. The DSC1101 series is a current production family; new designs can commit to this order code without a near-term migration risk. Sourced through independent distribution, quoted to order against the BOM quantity.
