The DSC1018DI1-025.0000T is a 25 MHz MEMS-based oscillator from Microchip's DSC1018 series, delivering a CMOS output from a 1.8V supply rail.
Microchip lists the DSC1018DI1-025.0000T as Obsolete.
Low power and small footprint
The 2.50 mm x 2.00 mm 4-SMD no-lead package (0.90 mm seated height) is a compact footprint for space-constrained PCBs. Hand-soldering is possible with a fine-tip iron and steady hands, but a hot-air station is cleaner for the no-lead land pattern.
