The DSC1033BI2-014.3180T is a Microchip PureSilicon™ MEMS-based XO delivering a fixed 14.318 MHz CMOS output from a 3.3V supply rail.
Housed in a 4-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm max. The 0.197" × 0.126" land pattern is a common footprint shared with many quartz XOs in this form factor, making it a drop-in candidate for existing PCB layouts that expect a standard 5×3.2 mm oscillator.
The output frequency is 14.318 MHz, a standard reference for many MCU clock inputs, video timing, and serial data rates.
When the standby (power-down) function is asserted, the disable current is 1 µA max. In active mode the supply current is 3 mA typical.
The DSC1033 series uses a common 4-SMD no-lead 5.0×3.2 mm footprint. Many standard quartz XOs in the same package and pinout (e.g., 14.318 MHz, 3.3V, CMOS) can be cross-referenced, but confirm the standby function and ±25 ppm stability match your BOM requirements before substituting.
