20 MHz MEMS XO with AEC-Q100 — automotive clock source in a 2.5 mm × 2.0 mm VLGA
The DSC6001JA3B-020.0000 is a 20 MHz MEMS-based oscillator from Microchip's DSC60XX series, delivering a CMOS output from a 1.71V to 3.63V supply rail. Its AEC-Q100 qualification means it is rated for automotive temperature and reliability stress — suitable for under-hood or cabin-domain ECUs where a quartz crystal would need a separate oscillator circuit and larger footprint. The Enable/Disable function lets the system gate the clock output without removing supply, useful for power-save modes in body controllers or sensor modules that sleep between CAN wake-ups.
Supply flexibility and current budget for mixed-voltage domains
The 1.71V–3.63V supply range covers 1.8V core logic and 3.3V I/O from the same oscillator — no level translation or separate rail needed. Maximum supply current is 1.3 mA typical, which keeps the thermal contribution negligible in a sealed ECU enclosure. The 4-VLGA package measures 2.50 mm × 2.00 mm with a seated height of 0.89 mm, fitting under low-profile connectors or alongside BGA memory on a dense automotive PCB.
Product status is Active, meaning no last-time-buy deadline or forced redesign. The part is available for new program designs and production replenishment through independent distribution channels — quoted to order against the BOM quantity.
