Product details

That stability means the clock edge jitter stays within a tight window across temperature swings — no external trim capacitor or calibration needed on the board. Supply voltage spans 1.8V to 3.3V, so the same part can run off a 1.8V core rail or a 3.3V I/O rail without a separate level translator on the oscillator output.

Automotive-grade qualification for under-hood and industrial use

Product status is Active.

Standby power-down and low-current operation

Normal operation draws 7.2 mA max, which is typical for a 66.6666 MHz CMOS oscillator and leaves headroom for the rest of the clock tree.

Housed in a 5.00 mm x 3.20 mm 4-SMD no-lead package, seated height 0.90 mm max.

Frequently asked questions

What is the standby current of DSC1001BL5-066.6666T?

When the standby (power down) function is active, the supply current drops to 15 µA max. Normal operation draws 7.2 mA max. The low standby current makes this part a good fit for battery-powered designs that need to conserve energy between active periods.

Can DSC1001BL5-066.6666T replace a standard quartz oscillator?

Yes — it is a drop-in MEMS replacement for a quartz XO in the same 5.00 mm x 3.20 mm 4-SMD package. The CMOS output is compatible with most clock inputs. The ±10 ppm stability matches or exceeds many quartz oscillators, and the MEMS construction is inherently more shock- and vibration-tolerant than a quartz crystal.
