How to choose: selection criteria and compatibility tips
Start with the target device. Check the MCU or transceiver datasheet for required clock frequency and acceptable input levels. Choose a packaged oscillator for plug-and-play clocking, or a crystal where low jitter and cost matter - pairing it with an appropriate oscillator circuit on your PCB.
Compatibility checklist
- Match frequency and output type (CMOS vs LVTTL).
- Confirm supply voltage - many oscillators run at 3.3 V or 5 V; some low-voltage parts target 1.8 V systems.
- Verify load capacitance and footprint for crystals.
- Consider temperature stability if your device will operate outdoors or near heat sources.
Example: swapping a 16 MHz crystal for a generic surface-mount part can fail if load capacitance differs. If your MCU expects a 16 MHz crystal with 12.5 pF load, choose a crystal specified for that or adjust the PCB’s load capacitors accordingly.
Specification callouts, bundles and pricing transparency
Communica lists price bands for single units and small packs; for bulk needs we provide quotes with lead times and VAT invoices for procurement. We also assemble accessory bundles: crystals with recommended load capacitors, oscillators with decoupling capacitors and socketed test adapters for benchtop verification.
Accessory bundle example
A common starter bundle: 16 MHz SMD oscillator, 10 nF decoupling cap, socket adapter and PCB footprint reference - useful for lab benches and student kits. Ask for bundle availability or request a tailored quote via the branch network.
Availability, lead times and branch pickup
We maintain stock at our Samrand HQ and branch warehouses. To check live availability or reserve parts for same-day collection, use our branches page: Branches & Trading Hours. For broader browsing, return to our homepage: Communica Home.
Objection handling and procurement notes
Concerned about lead time? We prioritise common frequencies and footprints for education and makers. Need traceable paperwork? We provide VAT invoices and quote documents for institutional purchases. Unsure which output type you need? Our technical staff will advise on compatibility before you buy or during quote preparation.
