Category: Ecliptek Corporation, Electronics, Oscillators

Product Overview

The EC2545TSY-30.880M TR is a high-drive, tri-state quartz crystal clock oscillator from Ecliptek Corporation. Designed for applications requiring a nominal frequency of 30.880MHz, this oscillator comes in a ceramic surface mount package (SMD) and is suitable for use in both HCMOS and TTL (CMOS 5.0Vdc) circuits.

Key Specifications

Electrical Characteristics: The device features a frequency tolerance and stability of ±50ppm, encapsulating all conditions such as calibration tolerance, frequency stability across its operating temperature range, supply voltage variation, output load changes, and the effects of shock and vibration. Aging is specified at a maximum of ±5ppm per year. The supply voltage is rated at 5.0Vdc with a ±10% allowance, while the input current does not exceed 10mA with no load. Output voltage for logic levels are 2.4Vdc (minimum) for the high state, and 0.4Vdc (maximum) for the low state, accommodating both TTL and CMOS loads. The oscillator maintains a duty cycle of 50% ±10%, and comes with a high drive capability, able to drive 10 TTL loads or a 50pF CMOS load. Rise and fall times are swift, at a maximum of 5ns, and phase jitter is kept at 1pSec maximum within a specified frequency range.

Environmental and Mechanical Durability

The EC2545TSY-30.880M TR is engineered to withstand harsh conditions, meeting multiple MIL-STD-883 standards for environmental durability, such as ESD susceptibility, fine and gross leak tests, mechanical shock resistance, and resistance to soldering heat. It is also compliant with UL94-VO for flammability, J-STD-020 for moisture sensitivity, and possesses a moisture resistance as per MIL-STD-883. Furthermore, the device adheres to standards for resistance to solvents, solderability, temperature cycling, and vibration.

Operating Conditions

The operational temperature range spans from -10°C to +70°C, with a storage temperature range stretching from -55°C up to +125°C. The pin connection carries a tri-state (high impedance) feature, providing flexibility in interfacing with different types of electronic circuits. The start-up time for the oscillator is marked at a maximum of 10ms.

Packaging and Availability

The unit is presented on a tape and reel for automated assembly processes. With its robust specifications and compliance with a myriad of industry standards, the EC2545TSY-30.880M TR oscillator is an ideal choice for precision timing applications within its operational parameters.
