Ecliptek Quartz Crystal Clock Oscillators Datasheet

Category: Ecliptek Corporation, Electronics, Oscillators

Overview

This datasheet provides detailed technical specifications for the Ecliptek Quartz Crystal Clock Oscillators, part number E13C7HZF-156.250M TR. Designed for electronic applications requiring precise timekeeping, this product features a nominal frequency of 156.250MHz and standard Low Voltage Positive Emitter Coupled Logic (LVPECL) output levels. The oscillator is packaged in a compact 6-pad, 5.0mm x 7.0mm ceramic surface mount device (SMD) suitable for high-density mounting.

Regulatory Compliance

The oscillator complies with various environmental and regulatory standards, including Lead-Free, EURoHS, ChinaRoHS, REACH 191 Substances of Very High Concern (SVHC), and it is DRC Conflict-Free.

Electrical Specifications

The device operates on a 3.3Vdc supply with ±5% tolerance and features an input current of 75mA maximum. Stability and tolerance are maintained within ±50ppm over the wide operating temperature range of -40°C to +85°C, accounting for calibration tolerance, supply voltage changes, aging, and environmental factors like shock and vibration.

Output voltage levels adhere to the standard LVPECL parameters, with logic high (Voh) and logic low (Vol) clearly defined alongside typical values for rise/fall times and duty cycle. The clock oscillator is capable of driving a 50 Ohms load into Vdd-2.0Vdc. Advanced phase noise characteristics are indicated, including an RMS phase jitter of 0.4pSec typical, and the datasheet provides the detailed noise performance at a range of frequency offsets.

Environmental & Mechanical Specifications

Durability and environmental resilience are addressed, with the datasheet listing ESD susceptibility in line with MIL-STD-883 standards and moisture resistance per MIL-STD-202 method. The part is also compatible with high temperature soldering processes, exhibiting a robust resistance to soldering heat, thermal shock, and temperature cycling.

Additional Features

Additional capabilities of the oscillator include tri-state and complementary outputs controllable via input voltage levels, along with a low standby current of 30pA maximum in the absence of load. Start-up time is specified at 10mSec maximum, and storage temperature resistance ranges from -55°C to +125°C.
