Do these series offer a tri-state output function? These product series offer a tri-state output function to facilitate the customer's use of in-process assembly testing or for the use of multiple clocks on the same node. They feature a tri-state output control option on pad one (1) where the output is three-stated (tri-state condition) when the voltage at the control pad is set to a logic low state. In this condition (see figure below), the oscillator output buffer circuitry within the oscillator is shut down and the output pad is placed into a high impedance state. If the voltage at the control pad is set to no connect or a logic high state, the output is enabled (clocking). Note: The oscillator has an internal pull up resistor on the control pad. The respective series datasheet provides the VIH and VIL thresholds for control of the tri-state function. TEN10-001-005 Rev A Page 6 of 16 Ecliptek Frequently Asked Questions Figure: Tri-State Timing Diagram When entering the tri-state mode, the time from when the oscillator pad one input control reaches VIL and the oscillator output pad becomes high impedance is shown as tPLZ. When existing the tri-state mode, the time from when the oscillator pad one input control reaches VOH and the oscillator output begins clocking is shown as tPZL. For these series, characterization test data indicates that tPLZ is approximately 50nS and tPZL is approximately 2 to 3mS. Back to Top 13. Do these series offer a stand-by function? All of the 1.8VDC, 2.5VDC and 3.3VDC oscillator series (excluding the 5.0V series) contain a stand-by function for power management. All active circuitry within the oscillator is shut down when the voltage at the control pad is set to a logic low state. In this condition, the output signal is three-stated (tri-state). The oscillator output gate becomes high impedance and the oscillator input current on the power supply line is negligible. The maximum stand-by current is listed on the respective series datasheet. Back to Top 14. Can I obtain a non-tri-state function for these product series? These series of product only offers a tri-state option on pad one of the oscillator. The customer can use these oscillator series as a non-tri-state oscillator by setting the voltage on tri-state control (pad 1) to either no connect or logic high. The oscillator has an internal pull up resistor on tri-state control (pad 1). The respective series datasheet provides the VIH and VIL thresholds for control of the tri-state function. Back to Top 15. How do I specify the overall frequency stability for these product series? Ecliptek defines the frequency stability performance of the device inclusive of specific oscillator operating conditions. This is often called the "Inclusive Method". Ecliptek specifies the following parameters for this series of product: TEN10-001-005 Rev A Page 7 of 16 Ecliptek Frequently Asked Questions Calibration Frequency Tolerance at 25°C Frequency Stability over Operating Temperature Range Supply Voltage Output Load First Year Aging at 25°C 260°C Reflow Shock and Vibration Back to Top 16. What is oscillator aging and what are the aging specifications for these product series? Aging is the systematic change in frequency with time due to internal changes in the crystal and/or oscillator. Aging is often expressed as a maximum value in parts per million per year [ppm/year]. The rate of aging is logarithmic in nature. The following factors effect oscillator aging: adsorption and desorption of contamination on the surfaces of the quartz, stress relief of the mounting and bonding structures, material outgassing, and seal integrity. At a rated operating temperature of 25°C, these series of products typically age at a rate of less than ±3.0ppm over the first year, and less than ±1.0ppm over the following year, logarithmically declining each year thereafter. As shown on the respective series datasheet, Ecliptek specifies the aging parameter of the device inclusive of the overall oscillator operating conditions. Back to Top 17. What are the period jitter characteristics for these product series? Jitter is a time domain measurement and is typically specified in picoseconds (pSec). Ecliptek uses a proprietary oscillator design, exclusive processing methods, and a unique output driver circuit enabling these oscillator series to have exceptionally low period jitter. Please contact the engineering staff at Ecliptek for period jitter characterization information. Back to Top 18. What are the rms phase jitter and phase noise characteristics for these product series? RMS Period Jitter is a time domain measurement and is specified in picoseconds (pSec) as a maximum value. Phase noise is a measure in the frequency domain and is specified in decibels at various offset points from the carrier (-dBc/Hz). Phase jitter, (often called offset jitter) is derived from the phase noise measurement of the spectral density over a given offset bandwidth. Ecliptek uses a proprietary design, exclusive processing methods, and a unique ASIC output driver circuit enabling these product series to have exceptionally low phase jitter and phase noise. The rms phase jitter parameter can be found on the respective series datasheet. Please contact the engineering staff at Ecliptek for phase noise characterization information.

Is tight duty cycle (symmetry) available for these product series? Tight duty cycle (45% minimum, 55% maximum) is available for these product series. See the respective datasheet for measurement thresholds and load conditions. Back to Top 20. What are the output and output load characteristics for these product series? Ecliptek offers these product series with a low voltage high speed CMOS driver that enables the output signal to swing from ground to VDD. The oscillator output topology is designed so as to optimize circuit load matching and signal performance. Signal integrity is optimized when the low impedance output of the oscillator is driving a high impedance-low capacitance input. The output load specification is listed on the applicable datasheet. If a customer requires a different load from that specified on the datasheet, shapes), please contact Ecliptek with your custom requirements.

Is start-up time specified for these product series? As shown in the figure below, start-up time is defined as the time from when the power supply reaches its specified VIH value to the time the oscillator output signal amplitude reaches its steady state VOH output logic high level and the output is within the specified frequency tolerance. Figure: Oscillator Start-up Timing Diagram Note: In order to ensure proper start-up, the power supply start-up should have an exponential curve typical of a capacitive charge of a linear voltage ramp. If you have a special voltage start-up profile (i.e. odd ramp steps or shapes), please contact Ecliptek to discuss possible oscillator performance issues. For these series, characterization test data indicates that the start-up time is typically around 2 to 3mS. The maximum start-up time specification for these series can be found on the series datasheet. Back to Top 22. How do I electrically test these product series at my facility?
