The DSC1004DC1-050.0000T is a 50 MHz MEMS-based XO (Standard) from Microchip's DSC1004 series, delivering a CMOS output in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm. The supply voltage range of 1.8 V to 3.3 V covers common digital rails, and the standby (power-down) function drops current draw to 15 µA max, useful for battery-backed or sleep-mode circuits.
The part ships on Tape & Reel (TR), consistent with automated pick-and-place assembly. Store the reels in a dry environment — the MEMS resonator itself is not moisture-sensitive, but the plastic reel and carrier tape can absorb humidity over long storage.
MEMS vs. quartz — what the stability spec means
For a 50 MHz clock, this translates to a maximum frequency deviation of ±2.5 kHz — tight enough for most MCU and FPGA reference clocks, but not for precision RF or timekeeping applications that require ±25 ppm or better. Maximum supply current is 8 mA at 50 MHz, which is comparable to a standard quartz oscillator at this frequency.
