Product details

Operating from -40°C to 105°C and a 2.25V–3.6V supply, it fits industrial, outdoor, and engine-bay applications where a quartz oscillator might drift or fail under vibration — the MEMS resonator is inherently more shock-tolerant.

Supply voltage and temperature — one part covers multiple rails

The wide 2.25V–3.6V supply range means the same stocked part works on 2.5V and 3.3V logic rails without a separate voltage variant — simplifies BOM consolidation.

Package and footprint — 6-VDFN, 3.2 × 2.5 mm

Housed in a 6-VDFN measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm — a compact, low-profile surface-mount package that fits tight board stacks. The 6-VDFN has a central thermal pad; ensure the PCB has a corresponding ground-plane pad and via array for adequate heat spreading, especially at the 35 mA max supply current.

Frequently asked questions

How do I program the DSC1101CL5-PROG?

The DSC1101CL5-PROG ships blank (user must program). Microchip provides the TimeFlash programmer and software to set the output frequency within the 3.3 MHz to 170 MHz range. The part is programmed before reflow — no in-circuit programming support is documented for this blank variant.

Can DSC1101CL5-PROG replace a standard quartz oscillator?

Yes — it is a drop-in replacement for many quartz XO footprints (6-VDFN, 3.2×2.5 mm) with CMOS output. The MEMS resonator offers better shock and vibration tolerance than quartz, and the ±10 ppm stability matches typical quartz grades. However, because it ships blank, you must program it before assembly, which adds a step not required with fixed-frequency quartz oscillators.

What is the closest alternative to the DSC1101CL5-PROG?

Within the same DSC1101 series, fixed-frequency variants (e.g., DSC1101xx-xxxx) are available pre-programmed at order — no blank-programming step needed. The pinout and package are identical, so a fixed-frequency DSC1101 can serve as a direct second source if your BOM frequency is stable and you want to skip the programming step.
