Product details

MEMS oscillator at 1.5 MHz for industrial timing

The DSC1033AI1-001.5000 is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a fixed 1.5 MHz CMOS output with a standby power-down function that drops supply current to 1 µA when disabled. Operating from a 3.3V supply over -40°C to 85°C, it holds ±50 ppm frequency stability — suitable for industrial environments where temperature swings would pull a quartz oscillator off frequency.

Microchip lists the DSC1033AI1-001.5000 as Obsolete.

Package and footprint: 4-SMD no-lead exposed pad

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.
