Product details

The DSC1001CE5-148.5000T is a MEMS-based XO (Standard) delivering a 148.5 MHz CMOS output from a 1.8V–3.3V supply rail, with ±10 ppm frequency stability over its -20°C to +70°C operating range.

AEC-Q100 grade and temperature profile

Rated AEC-Q100: this is a qualified automotive component, not an industrial part dressed up as 'automotive-capable'.

When the standby pin is asserted, the oscillator stops and the output is tri-stated; the 15 µA disable current (max) is the only draw on the supply. This is useful in automotive body controllers that cycle between active and sleep states — the oscillator's draw sits below the module's own leakage.

Frequently asked questions

What is the standby function of DSC1001CE5-148.5000T?

The standby (power down) function disables the oscillator and tri-states the output, reducing supply current to 15 µA max. This is controlled by a dedicated enable pin — pulling it low puts the part into standby; pulling it high resumes normal operation.

Is the DSC1001CE5-148.5000T RoHS compliant?

The part is listed under the DSC1001 series, which is RoHS compliant per Microchip's standard material declaration. The 4-SMD no-lead package is lead-free and compatible with lead-free reflow profiles.
