The DSC1033AI1-050.0000 is a 50 MHz XO (Standard) oscillator from Microchip's PureSilicon™ MEMS family, delivering a CMOS output at 3.3 V supply.
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 – this is the standard 7x5 mm oscillator footprint, so it drops onto existing PCB pads without a layout change.
For a 50 MHz clock, ±50 ppm corresponds to a maximum frequency error of ±2,500 Hz, which is within the capture range of most UARTs and SPI interfaces without additional calibration.
It is a pin-compatible 7x5 mm 4-pad MEMS oscillator with CMOS output and 3.3 V supply. Provided the existing oscillator also uses the standard 7x5 mm footprint, CMOS output, and 3.3 V rail, the DSC1033AI1-050.0000 can replace it. Confirm the standby function pin mapping – on this part, asserting the standby pin (typically pin 1) disables the output and drops supply current to 1 µA.
