Product details

The DSC1001CC1-125.0000T is a MEMS-based oscillator delivering a 125 MHz CMOS clock from a 3.2 mm × 2.5 mm 4-SMD no-lead package. Supply voltage spans 1.8V to 3.3V, so the same part can clock a 1.8V FPGA core or a 3.3V microcontroller without a level translator on the output. The CMOS output swings rail-to-rail, which simplifies interface to standard logic families.

Standby power-down for battery-conscious designs

In a battery-powered system that sleeps most of the time, this lets the oscillator gate itself off when the processor enters deep sleep, preserving the battery without an external load switch.

AEC-Q100 qualification — automotive-grade reliability

Product status is Active.

Frequently asked questions

Is DSC1001CC1-125.0000T AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating. That means it passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up).

Does DSC1001CC1-125.0000T have a standby (power down) function?

Yes. The standby function reduces the supply current from 8.7 mA (max) to 15 µA (max). This is useful for battery-powered systems that need to gate the clock when the processor enters sleep mode.

What is the difference between DSC1001CC1-125.0000T and DSC1001CL1-125.0000T?

The difference is in the frequency stability grade. The DSC1001CC1-125.0000T specifies ±50 ppm stability, while the DSC1001CL1-125.0000T specifies a tighter stability (typically ±25 ppm). For most general-purpose clocking, ±50 ppm is sufficient; the tighter grade matters for precision timing applications like Ethernet or video interfaces.

Is the DSC1001CC1-125.0000T compatible with 3.3V supply?

Yes, the supply voltage range is 1.8V to 3.3V, so 3.3V is within the operating range. The CMOS output swings rail-to-rail, so at 3.3V supply the output high level is 3.3V, compatible with 3.3V logic families.
