The DSC1033DI1-069.1200 is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 69.12 MHz CMOS output from a 3.3V supply rail.
A board-level redesign may be required to migrate to a current-production oscillator.
Housed in a 4-SMD no-lead package measuring 0.098" x 0.079" (2.50mm x 2.00mm) with a seated height of 0.035" (0.90mm) — a compact footprint that matches many standard oscillator land patterns (e.g., 2.5 x 2.0 mm). Surface-mount assembly; the no-lead construction reduces parasitic inductance compared to a leaded package, which helps maintain signal integrity at 69.12 MHz.
