MEMS oscillator with 27 MHz CMOS output
The DSC1001CE2-027.0000B is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a fixed 27 MHz output in CMOS logic levels. It operates from a 1.8V to 3.3V supply rail, suiting mixed-voltage designs without a separate level translator. Frequency stability is ±25 ppm, which keeps the clock edge within tight timing margins for 27 MHz USB or Ethernet PHY reference applications.
AEC-Q100 qualification and standby function
Rated AEC-Q100, this oscillator is qualified for automotive-grade reliability stress and PPAP — suitable for infotainment, ADAS camera modules, or body-control ECUs that need a 27 MHz reference. A standby (power-down) function drops supply current to 15 µA max when disabled, preserving battery in always-on automotive modules. Quoted to order against the BOM quantity through independent distribution.
Package footprint and temperature range
Housed in a 4-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — a standard 3.2x2.5mm footprint that matches many crystal oscillator land patterns. Rated for -20°C to 70°C operating temperature, this is a commercial-grade part suited to indoor electronics, office equipment, and consumer automotive cabin modules — not for under-hood or outdoor extended-temperature environments.
