Automotive-grade MEMS clock – what the AEC-Q100 rating buys you
The DSC1001BI2-065.0000T: For an ECU or sensor module that sees under-hood heat or cold-crank vibration, the quartz can stays off the BOM — the MEMS resonator is silicon, not a crystal blank, so it doesn't suffer the same shock-induced frequency jumps. The 65 MHz CMOS output at ±25 ppm stability is tight enough to clock a 100BASE-T1 PHY or a CAN-FD controller without an external PLL — the jitter budget stays inside the transceiver's eye mask. Supply voltage spans 1.8V to 3.3V, so the same order code covers 1.8V MCU rails and 3.3V FPGA banks without a second line item.
Standby mode and power-down current
That 15 µA is low enough to leave the oscillator powered from a battery-backed RTC rail — no need for a separate load switch. The output goes high-Z in standby, so the downstream clock input sees a tri-state line; pull it to ground if the receiver lacks an internal pulldown.
Package, footprint, and layout fit
The 4-SMD no-lead package measures 5.00 mm × 3.20 mm with a seated height of 0.90 mm. The 0.90 mm height clears most enclosure lids and conformal coat layers.
Product status is Active — no NRND flag, no EOL notice.
