TEN10-001-001 Rev C Page 2 of 21 Ecliptek Frequently Asked Questions 1. What are the Ecliptek EV series of oscillators? These Ecliptek oscillator series are voltage controlled crystal oscillators (VCXO). These product series utilize a quartz crystal oscillator where the output frequency is controlled by an external control voltage applied to the input of the oscillator and the output frequency varies as a function of the input voltage. Back to Top 2. How do the EV series of oscillators work? A VCXO is a crystal controlled oscillator where the output frequency of the device is being controlled by the crystal and an external control voltage. VCXO's are designed with a varactor replacing a fixed capacitor internal to the oscillator. A varactor diode is a semiconductor device that behaves as a variable capacitor when a voltage is applied to it. Thus, when a change in the control voltage is applied to the control pad of the oscillator, it causes a change in the capacitance of the varactor diode. This results in a change in the overall load capacitance seen by the crystal internal to the oscillator. These changes in the circuit load capacitance cause changes in the oscillator output frequency due to crystal loading. As a result, variations in output frequency are achieved by variations in the external control voltage. This phenomenon is often called frequency modulation. Back to Top 3.

The package has a seam sealed metal cover that is case grounded for improved EMI performance. Back to Top 11. How do I specify a VCXO? There are two common methods customers and suppliers use for specifying VCXO's. The first method is to specify the performance of the device inclusive of all operating conditions. This is called the APR Method. The second method is to specify device performance under specific operating conditions and to specify separate operating parameters such as frequency deviation, frequency tolerance, frequency stability over operating temperature range, supply voltage, output load, and aging. This is called the Separate Method. These oscillator series use the APR Method for specifying the VCXO. This method utilizes the absolute pull range (APR) definition. The advantage of the APR Method is that a customer can simply specify one parameter, APR, rather than specifying many individual parameters such as frequency deviation, temperature stability over operating temperature range, output load, supply voltage, and aging. See the table below for a comparison of the APR Method and the Separate Method. VCXO Output Parameter APR Method Separate Method Calibration Tolerance ±10ppm MAX Stability over OTR ±40ppm MAX Stability vs. Supply Voltage ±5ppm MAX Stability vs. Output Load ±5ppm MAX Aging over 10 years ±10ppm MAX Pullability/Frequency Deviation ±150ppm MIN Absolute Pull Range (APR) ±80ppm Minimum Operating Temperature Range (OTR) -40°C to +85°C -40°C to +85°C Table: APR Method versus Separate Method As shown in the above table, the APR Method of ±80ppm minimum in the second column is equivalent to the Separate Method of ±150ppm pullability minimum in the third column. Back to Top TEN10-001-001 Rev C Page 6 of 21 Ecliptek Frequently Asked Questions 12. What is APR? APR stands for absolute pull range. APR is defined as the minimum guaranteed frequency deviation (specified in ±ppm) from the nominal frequency (F0) over all operating parameters. These operating parameters include: frequency tolerance, frequency stability over operating temperature range, supply voltage, output load, and aging. For example, a 35.328MHz VCXO used in a PLL clock recovery circuit that has a ±50ppm minimum APR specification will track or capture a ±50ppm maximum 35.328MHz source oscillator under all operating conditions. Back to Top 13. How do I specify the APR for these product series? For frequencies from 1.544MHz to 36.000MHz, these product series offer the following APR options: ±50ppm, ±80ppm, and ±100ppm minimum. For frequencies greater than 36.00MHz to 51.840MHz, these product series offer both the ±50ppm APR and ±80ppm APR option. For frequencies greater than 51.840MHz, these product series only offer the ±50ppm APR option. Back to Top 14. What are the control voltage range and control voltage specifications for these product series? The control voltage range (VCR) is the minimum and maximum voltage that can be applied to the voltage control pad (pad 1) of the oscillator. The control voltage range is 0.0VDC to VDD (Supply Voltage) for these product series. The control voltage (VC) is the voltage applied to the voltage control pad (pad 1) of the oscillator for the measurement of the APR test conditions. The control voltage is dependent upon the specific product series. The table below outlines the control voltage for each series.

What are the pullability or frequency deviation specifications for these product series? The pullability or frequency deviation of a VCXO refers to the amount of frequency change (in ppm) with respect to a change in the control voltage (VC). These parameters are specified when using the Separate Method mentioned above. The Ecliptek EV product series do not specify VCXO pullability or frequency deviation, these series specify the APR Method. As a matter of interest, the total pullability or frequency deviation of these product series is typically 200ppm to 400ppm over the control voltage test conditions, depending upon the APR option specified by the customer. If a customer would like to specify a VCXO using the Separate Method, please contact the Ecliptek Global Customer Support Team. Back to Top 16. What are the operating temperature range (OTR) options for these product series? Ecliptek offers a commercial temperature range of 0°C to +70°C and an industrial temperature range of -40°C to +85°C. Back to Top TEN10-001-001 Rev C Page 8 of 21 Ecliptek Frequently Asked Questions 17. What are the frequency tolerance/stability options for these product series? The frequency tolerance/stability for these series is ±50ppm maximum over the operating temperature range of 40°C to +85°C or 0°C to +70°C. Back to Top 18. 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 crystal 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 ±2ppm over the first year, ±1ppm over the following year, logarithmically declining each year thereafter. The aging parameters can be found on the applicable series datasheet. It should be noted that oscillator aging is inclusive of the APR. Back to Top 19. 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 (pS) 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 jitter and phase noise. The rms phase jitter and phase noise parameters can be found on the applicable series datasheets. Back to Top 20. Do these product series offer tri-state output capability? These product series offer tri-state output control on pad five (5) or on pad two (2). The output is three-stated (tristate condition) when the voltage at the control pad is set to a logic low state. In this condition, the oscillator continues to operate, but the output pad is now in 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 table below outlines the tri-state input control pad for each series.

Is tight duty cycle (symmetry) available for these product series? Tight duty cycle, specified as a maximum value, is not available for these product series. The duty cycle for these series is typically 45% minimum to 55% maximum. However, the specification limit is 40% minimum, 60% maximum (under all operating conditions). Back to Top 22. What are the output load options for these product series? These oscillators have a high speed CMOS output driver that enables the output signal to swing from ground to VDD.

What is the transfer function and what is the transfer function for these product series? Often called slope, the transfer function of a VCXO is the direction the frequency changes with respect to the control voltage. Positive slope means the output frequency increases with an increase in control voltage. Negative slope means that the output frequency is increasing with decreasing control voltage. The transfer function for these oscillator series is positive. Back to Top 24. What is linearity and what are the linearity specifications for these product series? Often called monotonic linearity, this parameter is the calculation of the frequency error expressed in percentage with reference from the best straight line curve fit drawn on the output frequency versus control voltage graph. The linearity curve is the relationship between output frequency versus control voltage. The linearity specifications can be found on the applicable Ecliptek datasheet. In a phase locked loop application, the linearity requirements may be very loose, while in a frequency modulation application the linearity requirement may be very stringent. Back to Top TEN10-001-001 Rev C Page 11 of 21 Ecliptek Frequently Asked Questions 25. What are the modulation bandwidth and input impedance specifications for these product series? Often called tuning or video bandwidth, modulation bandwidth (MBW) is the modulation frequency at the input of the VCXO at which the output frequency deviation decreases to -3dB of its DC value. Input impedance specifies the load of the VCXO control input pad (pad 1). The MBW and input impedance parameters can be found on the applicable Ecliptek datasheet. Back to Top 26. Is start-up time specified for these product series? Start-up time for these series is specified at 10mSec maximum. 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 us to discuss possible oscillator performance issues. Back to Top 27.
