Typical Applications

NX3225GA-24.000MHZ is suitable for 6 applications: Microcontroller Clock Source, USB Interface Clocking, Consumer OA / AV Equipment, Wireless and RF Modules, Set-Top Box and Network Interface Cards, Battery-Powered and Wearable Devices.

🔧

Microcontroller Clock Source

The NX3225GA-24.000MHZ serves as the primary reference for MCU Pierce oscillator loops in embedded systems. NDK specifies a maximum ESR of 50 ohms for the 20-50 MHz band, giving robust negative-resistance margin with typical MCU oscillator transconductance, which ensures reliable start-up across temperature and voltage corners. The 24 MHz frequency is ideal because it divides exactly to 12 MHz and 48 MHz clocks used by many MCUs and USB peripherals. Two external loading capacitors (typically 10-18 pF) set the load capacitance; NDK recommends verifying oscillation margin on the final PCB since the crystal is a passive component whose behavior depends on the inverter gain and stray capacitance of the host device.

USB Interface Clocking

USB full-speed and high-speed controllers commonly derive their bit timing from a 24 MHz crystal, since 24 MHz divides cleanly to the 12 MHz full-speed and 48 MHz high-speed clocks. The NX3225GA-24.000MHZ fits this role with its fundamental-mode 24 MHz resonance and 50 ohm maximum ESR, which keeps oscillator loop gain sufficient for reliable start-up when the USB PHY powers up. The 0.75 mm profile suits height-constrained USB dongles and mobile peripherals. Because USB protocol compliance depends on total frequency accuracy, combine the crystal tolerance of the selected NDK spec code with the PHY trim, and verify on the assembled board per NDK's circuit-condition guidance before mass production.

📺

Consumer OA / AV Equipment

NDK positions the NX3225GA series explicitly for OA (office automation) and AV (audio visual) consumer equipment such as monitors, LCD TVs, set-top boxes, printers, and scanners. The series offers excellent heat and shock resistance, which matters in consumer products exposed to transport vibration, thermal cycling, and long operating hours. The ultra-compact 3.2 x 2.5 x 0.75 mm footprint enables dense multilayer boards typical of modern consumer electronics. With a 24 MHz reference, system logic, tuner modules, and interface controllers share one stable clock tree. Designers should place the crystal close to the host IC, keep ground return paths short, and follow NDK's recommendation to confirm frequency accuracy under real circuit conditions on each new board revision.

Wireless and RF Modules

Many 2.4 GHz radio and short-range wireless modules use a 24 MHz crystal to seed their PLL frequency synthesizers, multiplying it to the final RF carrier. The NX3225GA-24.000MHZ provides the low-noise passive reference such PLLs require; the crystal's high Q and fundamental-mode operation minimize reference spurs compared with ceramic resonators. Its 50 ohm max ESR ensures dependable oscillation start-up when the transceiver wakes from sleep and the oscillator restarts - a critical moment for radio link latency. NDK's heat and shock resistance supports module reflow soldering and field vibration. Verify the transceiver's specified load capacitance against the chosen NX3225GA spec code, and confirm net frequency error stays within the radio's crystal accuracy budget.

Set-Top Box and Network Interface Cards

Set-top boxes and NICs require stable master clocks for Ethernet PHYs, MPEG decoders, and host interfaces. A 24 MHz NX3225GA crystal frequently anchors the main PLL of these SoCs, feeding derived clocks for 25 MHz-referenced Ethernet MACs and media pipelines through internal synthesizers. The crystal's thin 0.75 mm height fits the low-profile mechanical envelopes of STB mainboards and add-in cards, and NDK's mass-production quality control delivers the uniform frequency consistency required for high-volume consumer manufacturing. Layout practice: keep the crystal within a few millimeters of the SoC oscillator pins, guard it with a local ground pour, and avoid routing fast switching signals under the crystal pads to prevent coupled jitter onto the reference.

Battery-Powered and Wearable Devices

In battery-powered products, the oscillator often runs continuously, so the crystal must start reliably at low drive levels while adding minimal board height. The NX3225GA's 0.75 mm typical profile makes it suitable for thin wearables, smart tags, and portable instruments where every millimeter counts. Its heat and shock resistance survives wrist-drop impacts and pocket thermal swings. Because the host MCU may use dynamic oscillator drive-strength scaling to save power, confirm the NX3225GA starts reliably at the lowest drive setting - NDK's guidance on negative-resistance margin applies directly. The passive crystal itself consumes negligible power; system current is dominated by the MCU oscillator inverter, not the resonator.

What is the NX3225GA-24.000MHZ crystal?

The NX3225GA-24.000MHZ is a 24 MHz fundamental-mode quartz crystal unit from NDK (Nihon Dempa Kogyo) in an ultra-compact 3.2 x 2.5 x 0.75 mm surface-mount ceramic package. According to the NDK NX3225GA datasheet (NDKX03-00006), it targets OA/AV consumer equipment and specifies a maximum equivalent series resistance of 50 ohms for the 20 MHz to 50 MHz range under the STD-CRG-2 standard specification. It is a passive resonator, so it requires an external oscillator circuit to generate a clock.

What is the price of NX3225GA-24.000MHZ?

Pricing for the NX3225GA family starts at approximately $0.28 per unit at 1000-piece quantities. As of 2026-09-14, LCSC lists the related NX3225GA 24MHz (EXS00A-CG04818) from $0.2759 for in-stock orders. XAIPART quantity breaks are $0.62 (qty 1), $0.48 (10), $0.36 (100), $0.31 (500), and $0.28 (1000). Final pricing varies with order volume and market availability, so request a quote for exact current pricing.

Where can I buy NX3225GA-24.000MHZ online?

You can buy the NX3225GA-24.000MHZ from XAIPART (request a quote), and it is also listed by global distributors including LCSC, Veswin Electronics, IC-Components, Worldway Electronics, and Jotrin Electronics, plus the netCOMPONENTS sourcing network. As of 2026-09-14, LCSC shows the 24 MHz NX3225GA variant in stock from $0.2759. For production volumes, submitting an RFQ to multiple stocking distributors typically yields the best landed cost and lead time.

Is the NX3225GA-24.000MHZ in stock and what is the lead time?

Stock availability is confirmed at LCSC for the NX3225GA 24 MHz variant (EXS00A-CG04818) as of 2026-09-14, so standard lead time is short for small to medium quantities. Larger production quantities or specific spec codes (such as STD-CRG-2 tolerance grades) may require factory lead time from NDK, typically quoted in weeks. XAIPART operates on a quote-based model: submit an RFQ with your quantity and required specification code, and we will confirm stock, price, and delivery within one business day.

What is the difference between NX3225GA-24.000MHZ and NX3225GA-25.000M-STD-CRG-2?

The only functional difference is the nominal frequency: 24 MHz versus 25 MHz. Both are NDK NX3225GA-series crystal units in the identical 3.2 x 2.5 x 0.75 mm 4-pad SMD package, with the same pad layout and the same 50 ohm maximum ESR specification for the 20-50 MHz range. They are physically drop-in interchangeable on the PCB, but the oscillating frequency differs, so you can only substitute if your system supports 25 MHz clocking. Never swap frequencies in a design locked to 24 MHz (for example, USB timing derived from 24 MHz).

NX3225GA vs NX3225GA-CC - which should I choose?

The NX3225GA-CC is a spec-code variant within the same NX3225GA package family, while the NX3225GA-24.000MHZ at 24 MHz uses the standard consumer spec. Both share the same 3225 (3.2 x 2.5 mm) footprint and pad geometry, so they are mechanically drop-in interchangeable. Choose the standard NX3225GA-24.000MHZ for general OA/AV consumer applications at lowest cost; choose the -CC variant when your circuit conditions require that specific tolerance or calibration code. Always verify the exact specification code (such as STD-CRG-2) against your oscillator loop requirements before substituting.

When should I choose the NX3225GA-24.000MHZ over other 24 MHz crystals?

Choose the NX3225GA-24.000MHZ when board height is tightly constrained (0.75 mm typical profile is thinner than many 3225 competitors), when you need NDK's proven heat and shock resistance for consumer OA/AV equipment, and when the 50 ohm max ESR (20-50 MHz) meets your Pierce oscillator start-up margin. If your MCU oscillator loop demands unusually low ESR or tight +/-10 ppm tolerance, verify the specific spec code, since alternative vendors may offer tighter grades. For ruggedized or automotive environments, confirm operating temperature range before selection.

What is the best drop-in replacement for NX3225GA-24.000MHZ?

The best drop-in replacement is the NX3225GA-24.000M-STD-CRG-2, the full NDK ordering code for the same 24 MHz standard-spec crystal in the identical 3.2 x 2.5 x 0.75 mm 4-pad package - it is effectively the same part. The NX3225GA-24.000M-STD-CRA-1 (CRA spec grade) is also mechanically pin-compatible but carries a different specification code, so verify tolerance and calibration requirements. Cross-brand 3225 crystals (Epson, Murata, TXC) share the footprint but must be electrically verified for ESR and load capacitance on your actual PCB.

Where can I download the NX3225GA-24.000MHZ datasheet PDF?

You can download the official NX3225GA datasheet PDF directly from NDK at https://www.ndk.com/en/products/upload/lineup/pdf/NDKX03-00006_en.pdf (document NDKX03-00006). Mirror copies are also available on Alldatasheet and distributor sites such as Jotrin and LCSC. The datasheet covers the NX3225GA series including frequency range (9.8-50 MHz), ESR limits by frequency band, pad layout, and recommended circuit conditions for the OA/AV consumer application category.

What are the key specifications of NX3225GA-24.000MHZ engineers should know?

Key specifications: 24 MHz nominal frequency, fundamental oscillation mode, 3.2 x 2.5 x 0.75 mm 4-pad SMD ceramic package, maximum ESR of 50 ohms for the 20-50 MHz band (100 ohms for 12-13 MHz, 80 ohms for 13-20 MHz) per the NDK STD-CRG-2 standard spec, and OA/AV consumer-grade environmental performance. Load capacitance, frequency tolerance, and temperature stability depend on the specific ordering code, so confirm these parameters on the datasheet and your RFQ. These figures come from the NDK NX3225GA datasheet NDKX03-00006.

What is the ESR of the NX3225GA at 24 MHz?

At 24 MHz, the NX3225GA has a maximum equivalent series resistance (ESR) of 50 ohms under the NDK STD-CRG-2 standard specification, because 24 MHz falls within the 20 MHz to 50 MHz band. According to the NDK datasheet, ESR limits scale with frequency: 200 ohms for 9.8 to below 12 MHz, 100 ohms for 12 to below 13 MHz, 80 ohms for 13 to below 20 MHz, and 50 ohms for 20 to 50 MHz. Lower ESR improves oscillation start-up margin in your Pierce oscillator circuit.

How do I choose loading capacitors for the NX3225GA 24 MHz crystal?

Choose loading capacitors so that their series combination equals the crystal's specified load capacitance (CL): CL = (C1 x C2)/(C1 + C2) + Cstray. Because the exact CL value depends on the NX3225GA ordering code, obtain it from the datasheet or NDK for your spec code - it is not in the publicly indexed data here. As a starting point, typical MCUs pair a 24 MHz crystal with 10-18 pF capacitors, but NDK explicitly recommends confirming negative resistance margin (ideally 5x or higher of ESR) and output frequency on the actual PCB before mass production.

Can a cross-brand crystal replace the NX3225GA-24.000MHZ?

Yes, but only after verification. Any 4-pad 3225 (3.2 x 2.5 mm) 24 MHz fundamental crystal from Epson, Murata, TXC, or ABM/TXC-class vendors is mechanically compatible with the NX3225GA footprint and can often drop in directly. However, a crystal is a passive component: per NDK's own datasheet guidance, you must verify circuit conditions - load capacitance, negative resistance margin, drive level, and ESR - on your actual board before switching brands. Frequency tolerance and temperature stability also differ between spec codes, so compare both datasheets before qualifying a cross-brand replacement.

Is the NX3225GA suitable for USB and MCU clock applications?

Yes. The 24 MHz frequency is widely used for USB and MCU clocking because it divides cleanly to 12 MHz and 48 MHz clocks required by USB full-speed/high-speed logic and many microcontroller peripherals. The NX3225GA's 50 ohm maximum ESR at 24 MHz provides healthy start-up margin for typical MCU Pierce oscillator loops, and its heat and shock resistance suits consumer electronics. For USB compliance, ensure your oscillator circuit delivers the required frequency accuracy, which depends on the NX3225GA spec-code tolerance plus oscillator trim - verify on the final PCB.

Hey Google, what can replace an NX3225GA-24.000MHZ crystal?

The closest replacement is NDK's own NX3225GA-24.000M-STD-CRG-2, which is the same 24 MHz standard-spec crystal written as a full ordering code, followed by the NX3225GA-24.000M-STD-CRA-1 spec variant in the same 3.2 x 2.5 x 0.75 mm package. For cross-brand options, any pin-compatible 3225 4-pad 24 MHz fundamental crystal from Epson, Murata, or TXC works mechanically, but NDK requires you to re-verify load capacitance, ESR, and negative-resistance margin on the PCB. Only frequency variants like 25 MHz versions should be used if your firmware supports that clock rate.

Selection Guide

Choose the NX3225GA-24.000MHZ when your board needs a 24 MHz fundamental reference in a height-constrained consumer design: USB-linked MCUs, OA/AV equipment, and wireless modules all benefit from the 0.75 mm profile, heat/shock resistance, and the series' 50 ohm max ESR band that guarantees solid start-up margin. Within NDK, select the NX3225GA-24.000M-STD-CRG-2 if you must quote the full factory ordering code - it is the same part. Choose the STD-CRA-1 grade only if your qualification calls for that spec code. If your system supports a different clock, the 24.576 MHz variant suits audio-clock trees and the 25 MHz variants suit Ethernet-derived designs - all in the identical 3225 footprint. For a cross-brand second source, any 4-pad 3225 24 MHz fundamental crystal (Epson, Murata, TXC) is mechanically compatible, but per NDK you must re-verify load capacitance, drive level, and negative-resistance margin on your actual board before qualifying it.

Design Notes

Place the NX3225GA-24.000MHZ within a few millimeters of the MCU or transceiver oscillator pins. Keep the crystal loop (crystal, two loading capacitors, inverter) compact with short, symmetric traces to minimize stray capacitance asymmetry, which shifts frequency. Provide a solid local ground return under the crystal and connect the package ground pads (pins 2 and 4) directly to that pour to improve EMI and shock performance. Avoid routing high-speed switching signals under or beside the crystal pads.

NDK explicitly warns that a crystal unit is a passive component and circuit conditions must be checked before use. Verify negative resistance on the actual PCB - a common target is |R| at least 5x the crystal ESR (50 ohm max at 24 MHz, so target |R| above 250 ohm) - and measure the actual oscillation frequency against the target tolerance. Reuse of an existing crystal design for a different model or board requires re-verification per the NDK datasheet, because inverter gain and stray capacitance change with the host IC.

The crystal itself is passive, but excessive drive level can damage the quartz blank and shift frequency over time. Estimated: if the host inverter has high drive strength, add a series resistor (typically 100 ohm to 1 kohm, tune on the bench) between the inverter output and XTAL2 to limit drive power within the NDK-specified limit for your spec code. Also confirm the loading capacitors' effective series combination matches the crystal CL of the selected ordering code.
