The DSC1033CE2-022.5792T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 22.5792 MHz CMOS output from a 3.3V rail. That frequency is a standard master clock for audio sample rates (e.g., 48 kHz and its multiples), so you'll see it on audio codec boards, HDMI audio extractors, or any digital audio interface that needs a clean, low-jitter reference. The 4-SMD no-lead package (3.20 mm × 2.50 mm) is a common footprint.
Microchip lists the DSC1033CE2-022.5792T as Obsolete. That feature is common across the DSC1033 family, so a replacement candidate should also offer a standby pin to match the BOM wiring.
That's a solid industrial-grade spec — enough for most audio and logic timing without extra clock cleaning. The 3 mA max supply current is low enough that a small 3.3V LDO can feed it without thermal worry, even in a cramped enclosure. The CMOS output swings rail-to-rail and drives standard logic inputs directly — no level translation needed if the downstream device runs on 3.3V.
