The DSC1001BE2-025.0000 is a 25 MHz XO (Standard) MEMS oscillator from Microchip Technology's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range.
Supply range, standby, and current draw
Operating from a 1.8V to 3.3V supply, this oscillator fits into mixed-voltage designs without a separate level translator for the clock line — the CMOS output swings rail-to-rail, so it drives a 3.3 V logic input directly from a 1.8 V core rail.
Package, footprint, and layout fit
Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm, the footprint matches the industry-standard 5.0 x 3.2 mm oscillator land pattern — a direct drop-in for many quartz oscillators of the same size. Surface-mount assembly on standard FR-4; no special via-in-pad or thermal management required. The no-lead construction keeps the parasitic inductance lower than a gull-wing package, which helps maintain clean clock edges at 25 MHz.
