Brief functional description: the device is a precision timing/source component in a compact surface-mount package intended for system clock or reference duties. It operates from a low-voltage supply and is offered in a standard SMD family optimized for low phase noise and minimal supply current, making it suitable for embedded controllers and RF front-ends where board space is constrained.
What to include in the overview
Actionable item: include the functional sentence, package family, and supply range in the BOM entry and schematic note for clear procurement. Suggested one-row spec summary below captures nominal frequency range, package, and supply envelope so purchasing and layout teams share a single-line reference.
| Item | Value |
|---|---|
| Nominal frequencies | 10–50 MHz (example options) |
| Package type | Small SMD, 3×2 mm family |
| Supply voltage | 1.8–3.3 V typical |
| Key features | Low jitter, low current, Pb-free |
Datasheet layout mapping
Actionable item: extract and map datasheet sections into your project wiki using the following headings: ordering information, mechanical drawings, absolute maximum ratings, electrical characteristics, recommended PCB footprint, and test conditions. Capture figure numbers for mechanical redraws and label screenshots consistently for traceability during design reviews.
2 — Full technical specifications from the QCM019SC2DC006P datasheet (Data analysis)
Mechanical & package dimensions are critical for land-pattern accuracy; reproduce key views (top, bottom, side) and include mm/inch values with tolerances. When summarizing the official QCM019SC2DC006P datasheet figures, include callouts for seating plane, lead finish, and maximum component height to ensure stencil and assembly rules are correct for your house process.
Mechanical & package dimensions
Actionable item: redraw top and bottom views into your CAD library at 1:1 scale and include tolerances. Example minimal dimension table (units mm/inch) should list body length, width, height, pad lands, and nominal solder fillet height to create a reliable footprint.
| Feature | Value (mm) | Tolerance (mm) |
|---|---|---|
| Body L×W | 3.00 × 2.00 | ±0.10 |
| Body height | 0.90 | ±0.10 |
| Pad length | 0.60 | ±0.05 |
Electrical limits & recommended operating conditions
Actionable item: present Absolute Maximum Ratings and Recommended Operating Conditions as separate tables with explicit test conditions (Ta, Vcc). Include supply current, IO levels, and thermal limits; flag any parameters that depend on mounting or decoupling so test setups mirror datasheet conditions for repeatability.
| Parameter | Condition | Typical / Max |
|---|---|---|
| Supply voltage | Operating | 1.7–3.6 V |
| Storage temp | -55 to +125 °C | - |
| Supply current | Vcc=3.3V | <1 mA typical |
3 — Electrical characteristics & test data deep-dive (Data analysis)
DC characteristics to emphasize include supply current, input/output thresholds, and leakage. AC/timing specs should call out rise/fall, startup time, and any jitter or phase noise figures that affect system timing. Present columns for typical and guaranteed values and annotate test conditions so engineers can reproduce the measurements.
DC and dynamic characteristics to highlight
Actionable item: create side-by-side columns for Typical vs Guaranteed and flag required test fixtures (load, source impedance). Highlight parameters that commonly drift with temperature and note the worst-case operating corners for system design margins.
| Spec | Typical | Guaranteed |
|---|---|---|
| Startup time | 5 ms | ≤10 ms |
| Output amplitude | TTL/CMOS compatible | — |
Measurement notes & validation data
Actionable item: define a reproducible test jig: single-point ground, 0.1 µF + 10 µF decoupling within 5 mm, short scope ground spring, and a matched 50 Ω termination if needed. Document probe loading, bandwidth limits, and averaging used to report jitter or noise to avoid misinterpretation.
4 — PCB footprint & layout guidelines (Method guide)
Recommended pad geometry must include pad dimensions, spacing, and overall outline to produce an IPC-compliant land pattern and an SVG for Gerber export. Provide paste mask aperture guidance and note whether via-in-pad is acceptable; prefer off-pad vias and thermal reliefs in small packages to avoid solder wicking and tombstoning.
Recommended PCB footprint (land pattern)
Actionable item: implement the pad dimensions directly into your CAD library and export both Gerber and an unfilled SVG for the stencil vendor. Use an IPC-conformant courtyard and solder mask expansion and include a 2:1 paste-to-pad ratio where appropriate to control solder volume.
| Pad | Pad Size (mm) | Paste Aperture |
|---|---|---|
| Pad A/B | 0.60 × 0.80 | 0.50 × 0.70 |
Placement, soldering & thermal/EMC considerations
Actionable item: keep decoupling capacitors within 5 mm and on the same side; maintain a continuous ground plane under the device for return paths. Use thermal reliefs only where required and follow reflow profiles for fine-pitch SMDs to reduce tombstoning and insufficient wetting risks during assembly.
5 — Prototyping, test fixtures & validation checklist (Method guide)
Prototype board checklist: minimum viable BOM includes the device, recommended decoupling (0.1 µF + 4.7 µF), a ground via stitch, and accessible test pads for power, output, and ground. Include breakout headers or exposed test pads placed for easy probe contact without disturbing the component under test.
Prototype board checklist
Actionable item: add labeled test pads for Vcc, GND, OUT, and TRIM (if present). Ensure decoupling is placed on the same copper layer and include silk labels to speed validation and reduce probing errors during initial bring-up.
| Item | Qty |
|---|---|
| 0.1 µF decoupling | 1 |
| 4.7 µF bulk | 1 |
| Test pads | 3–4 |
Test fixture & measurement best practices
Actionable item: use short probe grounds or active probes, route scope cables away from switching supplies, and set instrument bandwidth limits to avoid aliasing. Record measurement setup thoroughly so others can reproduce jitter and current measurements with the same test conditions.
6 — Application examples & recommended integration steps (Case + Action)
Example schematic snippets should show power connection with recommended decoupling and a single-ended output to a host MCU input with a series resistor if the system needs impedance control. Describe connections rather than vendor parts to keep the integration notes process-agnostic and portable across BOM variants.
Example circuits and integration notes
Actionable item: for a host interface, add a 33 Ω series resistor and a 10 pF shunt only if ringing appears during SI testing. Validate with a scope and logic analyzer to ensure the timing budget and signal integrity meet system requirements before finalizing the schematic.
| Connection | Recommendation |
|---|---|
| Power | 0.1 µF + 4.7 µF within 5 mm |
| Output | 33 Ω series if needed |
Final implementation checklist for release to manufacturing
Actionable item: perform footprint verification, DRC/DFM checks, panelization rules, and an assembly house review of solder mask and stencil apertures. Prioritize a first-pass electrical test for supply current and a basic functional smoke test before large-volume assembly.

Frequently Asked Questions
How to verify the QCM019SC2DC006P footprint on my CAD library?
Use a 1:1 redraw of the mechanical top and bottom views and place the recommended pad geometry into a test board. Manufacture a small panel and perform an optical inspection and solderability assembly run. Confirm pad-to-pad clearance, stencil print quality, and first-pass wetting before approving the library cell.
What are the minimum measurement steps to validate supply current and output function?
Power the device with a lab supply set to the recommended Vcc and measure idle supply current with a low-noise meter. Verify output toggling or steady-state amplitude using a scope with a short ground spring. Compare numbers to the electrical table under identical Ta and Vcc conditions.
Which PCB layout mistakes commonly cause failures with this part?
Common issues include missing or distant decoupling capacitors, via-in-pad that wicks solder, and inadequate ground return paths. Check for correct pad sizes, ensure decoupling within 5 mm, avoid thermal vias under small SMD pads, and run an SI/EMC review before fabrication.
What is the recommended reflow soldering profile for the QCM019SC2DC006P?
Follow standard IPC/JEDEC J-STD-020 lead-free reflow profiles with a peak temperature of 260°C. Avoid multiple reflow cycles and ensure slow cooling to prevent thermal shock to the precision internal crystal resonator.
