40 MHz MEMS XO — CMOS output, AEC-Q100, standby
The DSC1001AL5-040.0000T is a 40 MHz MEMS-based oscillator (XO) with a CMOS output, built on Microchip's DSC1001 series. Maximum active current is 7.2 mA. The package has a grounded thermal pad that should be soldered to the PCB ground plane.
Automotive qualification — AEC-Q100 Grade 1
Lifecycle status is Active. No EOL notice, no last-time-buy window. Startup time is also typically faster than a quartz oscillator, though the datasheet should be checked for the exact spec.
Package footprint and rework note
4-SMD, no-lead exposed pad — 7.00 mm x 5.00 mm body, 0.90 mm seated height. Standard reflow profile per JEDEC J-STD-020;. Confirm at RFQ for your volume.
