14.7456 MHz MEMS oscillator in a 2.5 mm × 2.0 mm package
The DSC1033DI1-014.7456 is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 14.7456 MHz CMOS clock output from a 3.3V supply rail. The 4-SMD no-lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm, fitting tight PCB layouts where a quartz crystal plus load caps would consume more board area. Typical supply current is 3 mA while active; the standby (power-down) function drops draw to 1 µA max, letting the oscillator gate itself off during system sleep without an external load-switch.
Active production — no end-of-life pressure
Because the DSC1033 series uses a MEMS resonator rather than a quartz blank, the oscillator is inherently more resistant to shock and vibration — a practical advantage in portable or motor-driven equipment where crystal failures from mechanical stress are a known field issue.
Standby function and power-down current
The standby (power-down) pin disables the output and reduces current consumption to 1 µA max. This is useful in battery-powered designs where the clock tree must be shut off during deep-sleep modes without a separate enable signal to the regulator.
