The DSC1001AI5-144.0000T is a 144 MHz XO (Standard) oscillator with CMOS output, built on a MEMS base resonator from Microchip Technology's DSC1001 series. It delivers ±10ppm frequency stability across a 1.8V to 3.3V supply range, drawing a maximum of 8.7mA from the rail — a fit for power-sensitive automotive ECUs that need a clean reference clock without a crystal's external load caps.
Housed in a 4-SMD, no-lead exposed pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, the DSC1001AI5-144.0000T mounts on a standard surface-mount footprint — the exposed pad should be soldered to a ground plane for thermal relief, though the 8.7mA draw keeps self-heating minimal.
