The DSC6003CI1A-000.0000 is a MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering a CMOS output clock from a 1 MHz to 80 MHz programmable frequency range. It operates from a 1.71V to 3.63V supply, drawing 1.3 mA typical, and is qualified to AEC-Q100 for automotive applications across -40°C to 85°C.
Blank (user-programmable) – what it means to order
This part ships as a blank device that the user must program to the desired output frequency using Microchip's programming tools — it does not come pre-configured. The programmable frequency range covers 1 MHz to 80 MHz, so a single order code can serve multiple clock requirements if the programming infrastructure is in place. Factor in programming time and tooling cost when sourcing this part for a BOM; a pre-programmed fixed-frequency oscillator may be a simpler alternative for production.
Package and mounting – board-fit details
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm footprint that matches many quartz oscillator pads. Surface-mount assembly with an Enable/Disable function pin; the no-lead construction keeps the parasitic capacitance low for clean clock edges at frequencies up to 80 MHz.
