The DSC1033CI1-050.0000T is a 50 MHz XO (Standard) from Microchip's PureSilicon™ MEMS oscillator family, delivering a CMOS output from a 3.3V rail. Frequency stability is ±50ppm, tight enough for most digital clocking — UART baud-rate generation, MCU system clocks, or Ethernet PHY reference.
Active current is 4mA max at 50 MHz, so the oscillator's draw is negligible in a system that already burns tens of milliamps on the MCU core.
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 oscillator footprint that matches many quartz XO land patterns.
