The 148.5 MHz output aligns with common video clock rates (e.g., 1080p/60 Hz), while the 14.7456 MHz output suits UART baud-rate generation or audio clocking — a single device replaces two quartz oscillators on the BOM. ## Supply voltage and output logic flexibility Operates from a 2.25V to 3.6V supply rail, so it can run directly from a 2.5V or 3.3V regulator without an external LDO — confirm the output logic level matches the downstream receiver's input threshold. ## Package and board layout notes Housed in a 20-VFQFN Exposed Pad package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — the exposed pad must be soldered to a thermal land on the PCB for proper heat dissipation and mechanical stability.","metaTitle":"DSC400-0103Q0102KE2 MEMS XO – 148.5 MHz & 14.7456 MHz","metaDescription":"Microchip DSC400-0103Q0102KE2 XO (Standard) with MEMS resonator, dual outputs 148.5 MHz & 14.7456 MHz, ±25 ppm stability, 2.25V-3.6V supply.
