Automotive-grade 20 MHz clock source with MEMS reliability
The DSC1004CL2-020.0000T is a 20 MHz MEMS-based oscillator delivering CMOS output across a 1.8V to 3.3V supply range — one BOM line covers 1.8V, 2.5V, and 3.3V logic domains without a secondary regulator. This is the under-hood or cabin-domain grade — the oscillator can be placed on the same board as the ECU's main processor without a separate derating analysis.
Standby power-down for battery-backed systems
In a telematics unit that sleeps between ignition events, this keeps the quiescent draw below the module's self-discharge budget — the MEMS resonator restarts in microseconds when the enable pin is asserted. Active-mode supply current is 6.5 mA max at 20 MHz, typical for a 1.8V–3.3V CMOS oscillator driving a 15 pF load. The MEMS base resonator consumes less power than a quartz crystal of the same frequency, which matters when the oscillator shares a 3.3V rail with a low-power MCU.
Product status is Active, meaning Microchip continues to manufacture and support the DSC1004 series.
4-SMD no-lead package and board layout
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint matches industry-standard 3.2 x 2.5 mm XO pads. The no-lead construction reduces parasitic inductance compared to a gull-wing package, which helps maintain clean clock edges at 20 MHz into a CMOS load.
