Overview
The Kyocera K3o 3C Series is a collection of high-reliability, miniature SMD (Surface-Mount Device) clock oscillators, presented in a ceramic package. These components are designed for a voltage supply of 3.3V and cater to a wide range of applications where precision and reliability are paramount.
Features
Some standout features include a frequency range spanning from 8 MHz to 67 MHz, with a standard frequency tolerance of ±50 ppm. The series also offers a tristate output inhibit function, enabling the oscillator’s output to be set to high impedance, therefore contributing to reduced power consumption. Speaking of efficiency, these oscillators boast low current consumption characteristics, making them suitable for power-sensitive devices.
Applications
The K3o 3C Series is adaptable to an array of electronic devices such as PDAs, notebook PCs, and portable electronics, due to their miniature form factor and precise operating parameters.
Ordering Information
The ordering code for these components clearly reflects the series, operating voltage (3C for 3.3V), and desired frequency, which is available in a variety of standard frequencies. Packaging is in tape and reel format, with each reel containing 1,000 units to facilitate mass production and automated assembly processes.
Electrical Specifications
With an operation temperature range of -10 to 70°C and storage temperatures from -55 to 125°C, these oscillators show versatility across different environmental conditions. They also have a low supply current requirement of 25 mA maximum when loaded. Standby current is notably efficient at 10 mA maximum, and the duty ratio (the proportion of time the signal is high to the total period) is standard between 40% to 60%, with an option for a tighter range of 45% to 55%.
Enable/Disable Function
The enable/disable function, labeled ‘E’ when with function, is represented in the series’ part number and signifies a control pin setup that can toggle the oscillator between active oscillation and a high impedance state for power management.
Reliability and Quality
Kyocera’s commitment to quality is evident in the device’s aging specification, which is measured at ±5 ppm per year, indicating the device’s frequency stability over time. Additionally, the oscillators offer predictable rise/fall times (10 ns maximum) and enable/disable times (5 ms maximum), ensuring reliable and consistent timing signals for sensitive digital electronic systems.
Dimensions & Packaging
The oscillators are presented in a compact size with a footprint of 5.0 x 3.2 x 1.4 mm (L x W x H) and are delivered in bulk with 1,000 pieces per reel aligning with the industry’s tape and reel packing standards.
Pin Connection
The device pinout includes connections for power supply (+Vcc), ground (GND), output, and the enable/disable control (CONTROL). Pin #1 denotes CONTROL, and Pin #2 serves as GND, with the duty cycle controlled via Pin #3, and the remaining pin dedicated to the oscillator output.
