66.6666 MHz MEMS XO with CMOS output
Microchip DSC1001CE1-066.6666T is a MEMS-based XO (Standard) delivering a 66.6666 MHz CMOS output — a common clock frequency for Ethernet PHYs, CAN controllers, and MCU oscillators in automotive and industrial systems. The ±50 ppm frequency stability holds the clock edge within tight jitter budgets for 10/100BASE-T and CAN-FD timing without external tuning.
Operating temperature is -20°C to +70°C, a commercial range that fits interior electronics and infotainment, but not under-hood or outdoor enclosures where -40°C is required.
Active production — order via RFQ
Supply voltage spans 1.8V to 3.3V, covering the three most common digital rails in a single BOM position — no level translation needed when moving between logic families.
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm (0.126" x 0.098") with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts in automotive modules and portable equipment.
