Product details

The DSC1001CI5-004.9152T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a fixed 4.9152 MHz CMOS output.

Supply voltage and power-down current

Runs on any rail from 1.8 V to 3.3 V — no separate regulator needed when the board has both 3.3 V and 1.8 V domains.

Temperature range and frequency stability

Rated -40°C to 85°C with ±10 ppm frequency stability — that keeps the clock within a few hundred Hz of 4.9152 MHz across the full temperature swing. For a CAN bus node or a USB controller, that margin is tight enough to avoid bit errors without a TCXO.

Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm.

Frequently asked questions

Is DSC1001CI5-004.9152T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating. That means it passed the automotive-grade reliability tests: extended temperature cycling, ESD tolerance, and latch-up immunity. It's suitable for under-hood and cabin electronics without additional screening.

Is there a pin-compatible cross reference for DSC1001CI5-004.9152T?

No direct second-source or cross-reference is listed in Microchip's documentation. The DSC1001 series is a proprietary MEMS oscillator family; a quartz XO with the same 3.2 x 2.5 mm footprint and 4.9152 MHz frequency may fit mechanically, but the electrical specs (supply range, output drive, standby function) would need to be verified against the target circuit.

What is the standby power consumption of DSC1001CI5-004.9152T?

In standby (power-down) mode, the supply current is 15 µA max. That's low enough to leave the oscillator connected to a battery-backed rail without draining the cell during sleep periods.

Can DSC1001CI5-004.9152T be used as a drop-in replacement for a crystal oscillator?

Yes, if the original crystal oscillator was a 4.9152 MHz CMOS-output XO in a 3.2 x 2.5 mm 4-pin no-lead package running on 1.8 V to 3.3 V. The MEMS construction is less sensitive to vibration and has faster start-up than a quartz resonator, so the board may actually see better jitter margin. Always confirm the supply voltage and output load capacitance match the original design.
