The DSC1033BI1-050.0000T is a MEMS-based oscillator from Microchip's PureSilicon™ series, delivering a 50 MHz CMOS output from a 3.3V supply.
Active current is 4 mA typ at 50 MHz, so the standby savings are meaningful in a duty-cycled system.
Design engineers and buyers need to know if the part is end-of-life and find a suitable replacement to avoid redesign.
Sourcing buyers need to quickly locate distributors with remaining inventory to fill BOM lines.
Maintenance techs and design engineers need pin assignments to ensure correct PCB layout and replacement.
Engineers must confirm voltage compatibility (3.3V) to avoid damage and ensure signal integrity.
Buyers using mixed-voltage systems need to know if level shifting is required.
Brokers and procurement check cross-reference to find alternative manufacturers or equivalents when the part is scarce.
