EC2725ETTS-200.OOOM Series Quartz Crystal Clock Oscillators

Category: Ecliptek Corporation, Electronics, Oscillators

The datasheet provides detailed specifications for the EC2725ETTS-200.OOOM series quartz crystal clock oscillators manufactured by Ecliptek Corporation. These oscillators are characterized by their nominal frequency of 200.000MHz and tri-state pin connection that allows for high impedance. They are designed as surface mount devices (SMD) and utilize Low-Voltage Complementary Metal-Oxide-Semiconductor (LVCMOS) logic levels.

ELECTRICAL SPECIFICATIONS

The nominal frequency mentioned is 200.000MHz with a tolerance and stability of ±25ppm maximum, which encompasses various factors including initial calibration at 25°C, temperature range frequency stability, voltage changes, load changes, and effects of shock and vibration. The oscillator demonstrates an aging rate of less than ±5ppm per year. Specified for operation between -40°C to +85°C, it requires a supply voltage of 2.5Vdc ±5%. It has a maximum input current requirement of 5mA and can drive a load of up to 15pF.

The output voltage holds two states: logic high (Voh) at a minimum of 90% of Vdd, and logic low (Vol) at a maximum of 10% of Vdd with a rise and fall time of 2nSec maximum, measured from 20% to 80% of the waveform. The duty cycle is defined as 50 ±10(%), measured at the midpoint of the waveform’s voltage.

The oscillator features a tri-state function that allows for high-impedance output when disabled. Enabling and disabling the output is controlled by tri-state input voltage (Vih and Vil) levels set to ≥90% of Vdd to enable and ≤10% of Vdd to disable the output, drawing a standby current of up to 10uA. RMS phase jitter is kept to less than 1pSec, measured between the frequencies of 12kHz to 20MHz. The start-up time is 10mSec maximum.

ENVIRONMENTAL & MECHANICAL SPECIFICATIONS

The device’s resilience to environmental and mechanical stress factors is also included in the datasheet. Its Electrostatic Discharge (ESD) susceptibility adheres to MIL-STD-883, Method 3015, Class 1, and is capable of handling 1500V Human Body Model (HBM). It has passed several MIL-STD tests for fine and gross leak, moisture resistance, mechanical shock, resistance to soldering heat, resistance to solvents, solderability, temperature cycling, and vibration, ensuring a robust build suitable for diverse applications. It is rated UL94-VO for flammability and conforms to J-STD-020 for moisture sensitivity level (MSL).
