Smart Meter Block Diagram

"Ceramic resonators" are used in the displays, ultrasonic flowmeter sensors, and microcomputers equipped in various smart meters (power, gas, heat, waterworks) while "crystal units" are used in the ICs for wired and wireless communication, and "piezoelectric sounders" are used for data reading check sound devices.

This section introduces "ceramic resonators (CERALOCK)."

Reasons Why Our Ceramic Resonators (CERALOCK) are Selected

Simple design

IC-timing device search tool that allows you to search for products and circuit constants suitable for the IC you use…①
Simple circuit configuration (CL mounting not required)…②

High reliability

High frequency concentration and stability with respect to physical changes
Frequency waveform stability (less jitter)

①IC-timing device search tool / SimSurfing

Enter the search conditions (IC name, etc.)
Press the Search button
The optimal IC circuit information is displayed

Try using it right away

You can easily confirm the recommended circuit conditions for various ICs.

②Simple circuit configuration

Compact size and enables the number of components to be reduced.

CERALOCK is more compact than conventional crystal units. Furthermore, because 萝莉影视 CERALOCK has two built-in capacitors, two external capacitors are not needed.

Contributes to space and mounting cost reduction

CERALOCK (three-terminal)

Conventional crystal units (two-terminal)

③Frequency waveform stability (low jitter)

Jitter is one indicator of the quality of a digital signal. Jitter primarily refers to the "timing fluctuation" of a digital signal. When the mutual timing relationship between circuits and devices deteriorates due to jitter, the system malfunctions and the accuracy decreases.

Jitter is reduced by using CERALOCK

The timing between circuits does not deteriorate, system malfunction is avoided, and accuracy is maintained.

Jitter occurs frequently in the built-in oscillation circuit of an IC

The timing between circuits deteriorates, and system malfunctions or declines in accuracy may occur.
