MEMS oscillator with dual LVDS clock outputs
The DSC400-0303Q0086KI1T is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two LVDS clock outputs at 148.5 MHz and 148.35 MHz — frequencies commonly paired in broadcast video and professional AV equipment where a pixel clock and a line-locked clock share the same oscillator.
Supply range, stability, and enable function
Operates from a 2.25 V to 3.6 V supply rail, so it can run from a 2.5 V or 3.3 V LDO without a separate regulator.
The 20-VFQFN exposed pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal pad on the PCB — the centre pad must be soldered to a ground plane for rated thermal performance.
