The operating temperature range is -20°C to 70°C, which suits office equipment, appliances, and indoor commercial electronics — not outdoor or under-hood environments. ## Standby function and disable current A Standby (Power Down) function pulls the output to high-impedance and drops supply current to 95 µA max — useful for battery-backed real-time clocks or power-gated subsystems where the oscillator only runs when the system is awake. Active supply current is 35 mA max — budget this into the rail's total draw. ## Package and footprint for PCB layout Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max — this is a low-profile, small-footprint oscillator that fits tight board stacks and leaves room for surrounding passives. Surface-mount mounting with the 6-VDFN land pattern — the exposed pad on the underside should be soldered to a ground plane for thermal and mechanical stability, though the datasheet's recommended footprint is the final authority for stencil aperture. Supplied in Tape & Reel — procurement quantities are reel increments; cut-tape or partial-reel availability is confirmed at RFQ.","metaTitle":"DSC1101CE5-045.1854T — Microchip MEMS XO, 45.1854 MHz, CMOS","metaDescription":"Active Microchip DSC1101 MEMS oscillator, 45.1854 MHz CMOS output, 2.25–3.6 V supply, -20 to 70°C, 6-VDFN.

MEMS oscillators typically offer faster startup, better resistance to shock and vibration, and tighter frequency stability over temperature without the aging drift of quartz. The electrical interface (CMOS output, 2.25–3.6 V supply) is the same — so in most designs it is a drop-in replacement for a quartz XO of the same frequency and package."},{"question":"What is the footprint of DSC1101CE5-045.1854T?","answer":"The 6-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The land pattern is a standard 6-pad DFN with an exposed ground pad — the recommended footprint is in the datasheet, but the outer dimensions match common 3.2 x 2.5 mm oscillator footprints used by other manufacturers."},{"question":"Can I get DSC1101CE5-045.1854T in a cut tape or full reel?","answer":"The standard packaging is Tape & Reel.
