MSTM MST1602 MEMS Oscillator: An Industrial-Grade Clock Solution

MST1602: Redefining the Benchmark for Industrial Clock Sources

MSTM’s MST1602 MEMS oscillator is now in volume production, shattering the limits of traditional quartz crystals:

• Ultra-stable across the full temperature range: ±20 ppm frequency accuracy from –40 °C to +125 °C (–55 °C to +125 °C on request), cutting temperature drift by 50 % versus quartz.  

• Unmatched shock and vibration immunity: survives >60 000 g shock and >70 g vibration—six times rocket-launch acceleration—eliminating vibration-induced clock failure.  

• Nanosecond-level start/stop precision: <5 ms start-up time safeguards data integrity during sudden power loss.  

• Ultra-low phase noise: 1.3 ps RMS jitter (12 kHz – 20 MHz) delivers precise timing for Gigabit Ethernet.

Proven performance in real industrial environments  

Application | Legacy pain point | MST1602 solution  

IP HD camera | Cold-start delay causes frame loss | <8 ms cold start at –40 °C, zero dropped frames at 4 K@60 fps  

PLC control | Vibration causes clock drift | <0.1 ppb offset under 70 g vibration  

SSD | High error rate at high temperature | BER <10⁻¹² at 125 °C  

Solar inverter | EMI disrupts PWM | Built-in EMI shield, ISO 7637-2 qualified

Five breakthrough technologies  

1. All-silicon MEMS core  

   • Single-crystal silicon resonator replaces quartz; aging <0.5 ppm/yr vs 3 ppm/yr for quartz, 6× longer life.  

2. Wide-voltage adaptation  

   • 1.62 V – 3.63 V input covers 3.3 V/1.8 V rails with ±15 % tolerance.  

3. Nano-scale packaging  

   • 2.0 × 1.6 mm, 2.5 × 2.0 mm, 3.2 × 2.5 mm options cut PCB area by 70 % in PLCs.  

4. Anti-sulfur corrosion  

   • Wafer-level silicon-nitride passivation resists sulfur-bearing gases; passes MIL-STD-883K Method 1009.8.  

5. 54 exact frequencies  

   • 3.57 MHz – 156.25 MHz (including 66.6666 MHz) for drop-in quartz replacement.

Mandu: End-to-end support for industrial upgrades  

As MSTM’s authorized distributor, Mandu delivers a three-tier service:

1. Pin-point selection  

   • Scenario-based models (e.g., PLC refresh period, SSD write bandwidth) yield the optimal frequency and package; 48-hour Clock Fit Report.  

2. Rapid validation  

   • Free samples plus:  

     – Temperature cycling (–55 °C ↔ +125 °C)  

     – Mechanical stress (60 000 g shock / 70 g vibration)  

     – EMC test (EN 55032 Class B)  

3. Mass-production care  

   • MEMS Oscillator Reflow Guide and failure analysis  

   • AEC-Q100 qualification assistance on request

Field-proven case studies  

• Industrial IoT gateway: 66.6 MHz multi-channel EtherCAT with <5 ns sync error, real-time control of 200 nodes.  

• EV on-board charger: 125 MHz clock enables 200 kHz SiC MOSFET switching, efficiency up to 98.5 %.  

• Surgical robot motor control: 150 MHz clock delivers 0.001° servo resolution and >90 % tremor suppression.

Why every engineer chooses MST1602  

1. Lifetime cost savings—40 % lower price than comparable OCXOs, MTBF >2 million hrs, 10-year maintenance-free.  

2. Drop-in domestic replacement—pin-compatible with Abracon/SiTime, no hardware or software changes.  

3. Extreme-environment reliability—passes MIL-STD-202G Method 213B shock test for nuclear or deep-sea use.
