That matters for battery-operated gear where every milliamp-hour counts. The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails without a separate LDO — one less component on the BOM. For a 125 MHz clock, that is ±6.25 kHz — tight enough for most Ethernet PHYs and FPGA reference inputs. The 6-SMD no-lead footprint (5.00 mm x 3.20 mm) is a standard MEMS oscillator land pattern — no via-in-pad or special stencil required.","metaTitle":"DSC1101BI1-125.0037 MEMS XO 125.0037 MHz CMOS - Microchip","metaDescription":"Active MEMS oscillator, 125.0037 MHz, CMOS output, ±50 ppm stability, -40°C to 85°C, 2.25-3.6V supply.

It is a drop-in MEMS replacement for a 125.0037 MHz crystal oscillator with CMOS output in a 5.0 x 3.2 mm 6-pin SMD package. The MEMS resonator is more rugged than quartz, but the output drive strength and rise/fall times are comparable. Confirm the enable polarity and pin 1 function on your existing footprint — the standby function uses the same pin as some quartz oscillators' output-enable."},{"question":"What does the standby power-down function do on this oscillator?","answer":"When the standby pin is asserted (typically pulled low), the internal MEMS resonator and output driver shut down, dropping supply current from 35 mA max to 95 µA max. The output goes high-impedance. The oscillator restarts within a few hundred microseconds after the pin is de-asserted — fast enough for most sleep/wake cycles."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1101BI1-125.0037","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1101BI1-125.0037 when reusing this data.
