• Wide Operating Voltage Range: It allows the device to operate from very low static power supply voltage down to 1.7 V.
• Low-Jitter Performance: It can provide low jitter performance with low power consumption.
• Accurate Frequency: The oscillator is able to accurately synchronize external clock signals with very low jitter.

Application

ASTMHTE-32.000MHZ-ZR-E is typically used in audio, portable consumer electronic, computer, communication, automotive, and security applications. It is ideal for applications requiring high-accuracy clock signals. These include optical network clocks, industrial clock cards, test equipment, GPS timing, and digital audio and video source/sink applications.

Working Principle

In operation, the device produces a clock output signal with a jitter that is fixed with respect to the REFOUT input signal. The jitter performance of the output signal is substantially determined by the phase noise characteristics of the REFOUT signal. The device is fabricated with an industry standard CMOS process and operates at a temperature range of -20 to +105 Celsius.

The oscillator consists of a voltage-controlled oscillator (VCO) and a phase-locked loop (PLL). The VCO is activated by an external clock signal applied to the REFOUT input. The VCO output frequency is compared to a reference frequency derived from the REFOUT signal and adjusted until the two frequencies match. The VCO operates with a center frequency of 32MHz and variation of the output frequency is limited to ±1%. The PLL maintains the output frequency and also generates the jitter-free output clock signal.

Conclusion

ASTMHTE-32.000MHZ-ZR-E is a versatile oscillator designed for a variety of applications. It is suitable for battery powered applications, demanding low-power operation, and provides an accurate output frequency and low jitter performance. With its wide operating voltage range and low-jitter performance, it is ideal for optical networking, industrial clock cards, test equipment, and digital audio and video applications.
