MEMS oscillator with dual fixed outputs
The DSC400-0103Q0102KE2 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two independent output frequencies: 148.5 MHz on output 1 and 14.7456 MHz on output 2, selectable as LVCMOS or LVDS. 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.
