The DSC1003AE1-050.0000T is a 50 MHz MEMS-based XO from Microchip's DSC1003 series, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to +70°C operating range. The supply voltage spans 1.7V to 3.6V, letting a single BOM line serve 1.8V, 2.5V, or 3.3V logic rails — useful when the same oscillator must feed a 3.3V MCU and a 1.8V PHY on the same board.
New designs and ongoing builds can proceed without a last-time-buy window.
Package and board layout notes
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm — the same footprint as standard 7×5 mm quartz oscillators, so a layout designed for a quartz XO accepts this MEMS part without a pad change.
