K5O-HC Series Clock Oscillators Overview
The K5O-HC series features high reliability within a ceramic SMD (surface-mounted device) package, especially designed for routers, switches, and servers. With a frequency range stretching from 8MHz to 68MHz, the oscillators offer frequency tolerances of ±100ppm and ±50ppm. They integrate robust construction with excellent overall performance suitable for a wide range of industrial applications.
Product Dimensions and Order Information
The dimensions of the K5O series are provided in both millimeters and inches, ensuring compatibility with various design standards. Ordering is made simple with a clear guide, where customers can specify series, frequency tolerance, packaging type, and the desired output frequency for their application needs.
Key Electrical Specifications
Output Frequency: The K5O series oscillators support an output frequency ranging from 8 to 68 MHz.
Frequency Tolerance: They offer a choice of ±100ppm or ±50ppm to suit various precision requirements.
Aging: Frequency stability is maintained over time with aging specified at 15ppm per year at 25°C.
Operating Temperature Range: These devices operate between -10 to 70°C, with extended operating temperature ranges available on request.
Supply Voltage & Current: Requires a supply voltage of 5±0.5V and has a maximum supply current of 50mA when loaded at 68MHz.
Output Logic Levels: Support CMOS logic levels with output levels specified at 0.1 Vcc max and 0.9 Vcc min for logic 0 and logic 1, respectively.
Functional Features
The K5O-HC series boasts a tristate output (output enable and disable function) with a control voltage (“High” or open for oscillation and “Low” for high impedance state). Additionally, they define parameters such as Duty Ratio, Rise/Fall Time, Load Capacitance, Enable/Disable Time, Input Voltage Levels, and Start-up Time, ensuring compatibility and ease of integration into various systems.
Applications and Options
These clock oscillators are suitable for use in networking equipment such as routers, switches, and servers. For those requiring specifications beyond what is offered in standard conditions, Kyocera invites customers to contact them for inquiries about extending the operating temperature range or other customized frequencies and conditions.
