74.25 MHz MEMS XO — video clock fit and standby function
The DSC1033CE2-074.2500T is a 74.25 MHz MEMS-based XO (Standard) with CMOS output, designed for surface-mount assembly in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm. 74.25 MHz is the standard pixel clock for 720p and 1080i video formats — this oscillator fits video encoder/decoder clock trees, broadcast gear, and display interface timing where a crystal resonator would require external load caps and a longer startup.
±25 ppm stability and 3.3 V operation
Operates from a single 3.3 V supply with a typical current draw of 4 mA — the low power and small footprint suit space-constrained boards where a crystal-plus-inverter solution would consume more area.
