SMD CLOCK SILICON OSCILLATOR FROM 0/+70°C TO -55/+125°C

The low-power, low-cost silicon clock oscillators from our product range are equipped with state-of-the-art IC technology and set the standard in terms of performance, extreme longevity (MTBF 1 billion hours), excellent shock and vibration resistance, size, precision, jitter, power consumption and flexibility. As with other silicon oscillators, our SMD silicon oscillators of the LPO, HTLPO, WTLPO series and the corresponding automotive versions (AEC-Q100) use a silicon resonator for synchronising the IC. Due to the very low vibration energy of the micro-silicon resonator, the performance of the SMD silicon oscillators is by far superior to the one of comparable quartz oscillators. Generally, the SMD silicon clock oscillators can be used in all applications where a very cost-efficient clock oscillator is required. Samples can normally be shipped on the same day, if they are requested before 2pm.

The trend towards SMD silicon oscillators continuous to grow rapidly. On the one hand, they are cost-efficient considering their performance and replace quartz oscillators, with the exception of TCXOs and VC-TCXOs, in all vertical markets and applications. On the other hand, the ultra-low power of 32,768 kHz and MHz oscillators allow up to 50% system energy savings – ask our specialist how this is possible.

Recommended version for new developments:

For new developments, we suggest to developers versions in the 2.0×1.6 mm or maximum in the 2.5×2.0 mm case, with a very wide supply voltage range of 2.25 – 3.63 VDC (-XX- in the article description), a frequency stability of ±20ppm@-40/+85°C, ±30ppm@-40/+105°C, ±30ppm@-40/+125°C, or ±50ppm@-55/+125°C, with the frequency of their choice. For the function of pin 1, we recommend using the standby function, even if this function is not necessarily required. Reason: On the one hand, the wiring requirements of pin #1 are very low in relation to the potential cost saving, Since we normally have large quantities with the standby function in stock, which makes short-term delivery at a very good price possible. Oscillators without standby function at pin 1 are manufactured in the required quantity, which is normally significantly more expensive. In the event that the required oscillator is not in stock, the standard delivery period, also for customised products, is 4 – 6 weeks maximum.

How the EMC behaviour can be improved without additional costs

The SMD silicon clock oscillators are equipped with the so-called SoftLevel function. Detailed information can be found in the following report:“How SMD silicon clock oscillator improves EMC – EMI”

The SoftLevel function is available at no extra cost and allows to reduce the rise/fall time of the output signal. This makes the edges of the output signal rounder; in the slowest version, the output signal resembles a shark fin. With an extension of the rise/fall time by up to 45%, the EMC attenuation at the 11th harmonic wave is above –60 dB. An enormous value for such an easy adaptation of trise and tfall.
