Microchip lists the DSC1033AI2-025.0000 as Obsolete.
Supply voltage is 3.3 V. Frequency stability is ±25 ppm.
Industrial temperature grade and low power
A 25 MHz oscillator with ±25 ppm stability across that span is a fit for outdoor telecom, factory-floor controllers, and engine-bay modules where a quartz oscillator might drift more with temperature.
Housed in a 4-SMD, no-lead exposed-pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The exposed pad under the package provides a low-thermal-resistance path to the PCB — the board copper area under the pad sets the junction-to-ambient thermal performance. Surface-mount assembly; the 0.50 mm pitch is standard for this form factor.
