Product details

The DSC1001CL2-020.0000 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 20 MHz CMOS output with ±25 ppm frequency stability across -40°C to 105°C — the industrial temperature band that covers engine-bay electronics, outdoor telecom base stations, and factory-floor motor drives.

Supply voltage range of 1.8V to 3.3V covers common digital rails — 1.8V for low-power MCUs, 2.5V for DDR memory interfaces, and 3.3V for legacy logic — so the same BOM line can serve multiple voltage domains without a level translator.

Package, footprint, and layout fit

Housed in a 4-VDFN package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, this oscillator fits the standard 3.2 x 2.5 mm MEMS oscillator footprint — a drop-in replacement for many quartz XO footprints of the same size. Surface-mount mounting with the 4-VDFN land pattern requires no special via-in-pad or thermal relief — the small pad area keeps the board layout simple on two-layer or four-layer PCBs.

Frequently asked questions

Where can I buy DSC1001CL2-020.0000 and how is it quoted?

Submit an RFQ with your target quantity — we confirm availability and current pricing per order. No stock-holding claim; lead time and price are quoted at RFQ.

Does DSC1001CL2-020.0000 meet AEC-Q100 requirements?

Yes, the oscillator carries an AEC-Q100 rating, meaning it has passed automotive-grade reliability testing for temperature cycling, ESD, and latch-up.

Can DSC1001CL2-020.0000 replace an older 20 MHz ceramic resonator?

No — this is a MEMS-based XO with a CMOS output, not a ceramic resonator. A ceramic resonator requires an external load capacitor and typically has wider frequency tolerance (±0.5% or worse). The DSC1001 delivers ±25 ppm stability and a clean rail-to-rail CMOS clock, but the circuit must be designed for an oscillator input, not a resonator input.

What is the footprint size of DSC1001CL2-020.0000?

The 4-VDFN package measures 3.20mm x 2.50mm with a 0.90mm seated height. This matches the industry-standard 3.2 x 2.5 mm MEMS oscillator footprint.

What is the standby function on the DSC1001?

The Standby (Power Down) function disables the oscillator output and drops the supply current to 15 µA max, compared to 6.3 mA max during active operation. The output goes high-impedance in standby, so the downstream clock input sees a tri-state condition — the receiving device must handle this with a pull-up or clock-gating logic.
