A device or component known as a data center clock generator is used in data centers to produce and transmit precise timing signals throughout the building.
These timing signals are essential for keeping the overall integrity and effectiveness of data center operations while synchronizing multiple operations.
All of the equipment and systems in the data center use the clock generator’s reliable and precise reference signal, which is normally in the form of a high-frequency electrical signal.
This covers crucial infrastructure elements such as servers, network switches, storage devices, and others. Atomic or precision quartz oscillators are frequently used by clock generators in data centers to produce extremely precise timing signals.
Data center clock generators help to the dependable and effective functioning of crucial applications and services hosted within the facility by maintaining perfect timing synchronization, ensuring seamless data processing, communication, and overall system performance.
It’s often referred to these components as frequency synthesizers or clock synthesizers as the complexity of the clock generator timing outputs increases.
To create the desired output signal, a frequency synthesizer may combine frequency multiplier, frequency divider, and frequency mixer operations.
The Global Data Center Clock Generator Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
VersaClock® 7 clock generators are a family of reconfigurable clock generators with an internal crystal oscillator for PCIe and networking applications in high-end computing, wired infrastructure, and data center equipment, according to Renesas Electronics Corporation, a leading provider of advanced semiconductor solutions.
Designers may set frequencies, I/O levels, and General Purpose I/O (GPIO) pin functionality with the VersaClock 7’s unequalled flexibility. By combining low power consumption, cost-efficiency, and a tiny package size, it sets a new standard.
The VersaClock 7 clock generators from Renesas Electronics offer a wide range of programmable settings that may be used to several designs. For system design margin and reduced BER, the VersaClock 7 has redundant input for backup and low phase noise.
For space and BOM optimization, the clock generators include an integrated crystal alternative. Renesas provides the new Renesas IC ToolBox (RICBox) Windows application that enables users to create configurations and program devices on evaluation boards in order to configure the VersaClock 7 devices.
A brand-new platform called RICBox has been launched to give consumers access to cutting-edge tools for Renesas product evaluation. Customers can customize setups and program VersaClock 7 devices on evaluation boards using either Python drivers or a Windows GUI.
High-performance, integer-based (M/N) clock generators designed specifically for small cell wireless applications are the Si538 JESD204B Clock Generators from Skyworks Solutions Inc. These require the best phase noise and integration performance.
Frequency synthesis and jitter attenuation are combined in the Skyworks Si538 Clock Generators to create a highly integrated digital system that does away with the requirement for extra VCXO and loop filter components.
A low-cost fixed-frequency crystal that offers frequency stability for free-run and holdover modes is a component of these devices.
The Si5332-AM has SmartClock technology built in, which uses Skyworks’ exclusive MultiSynth to monitor the condition of reference inputs, identify faults, report faults to a system safety manager, and, with external control, switch to a redundant backup source in the event of a fault.
The AlwaysOn mode enables the output clocks to continue running within +/-5% of the intended output frequency in the case of primary and redundant input reference failure. ClockBuilder Pro software enables rapid and simple configuration of the Si5332-AM.
Five distinct clock outputs are produced by Texas Instruments CDCE6214/CDCE6214-Q1 Ultra-Low Power Data Center Clock Generators, which can be switched between different driver modes.
Multi-function printers and enterprise computing for PCs and notebooks are other applications. The input source for the four-channel, medium-grade jitter clock generators can be a crystal, a single-ended or differential input clock source.
The CDCE6214/CDCE6214-Q1 clock generators have a frac-N PLL that can create any input frequency into an unrelated base frequency. The I2C interface can be used to configure the devices.
The clock generators can be set up in a variety of ways using Pin Mode on GPIO pins in the absence of a serial link. The CDCE6214-Q1 devices meet the requirements of AEC-Q100 for use in automotive applications.
The MicroClock Programmable Data Centre Clock Generators from Renesas Electronics 5X1503 and 5L1503 are perfect for low-power, consumer, battery-powered applications, wearable, and smart devices. The devices have a single implanted crystal and a 1 PLL + DCO architectural design.
The generators may generate up to three different frequencies and are OTP programmable. Unique features like Proactive Power Saving (PPS) are incorporated into the gadgets. To support the system’s date/time keeping clock, they have a low-power DCO.
Four different PLL frequencies can be switched between dynamically using Dynamic Frequency Control (DFC). This is accomplished by decreasing frequency overrun and undershoot (ORT) through external requests with controlled frequency shifts.
For EMI reduction, the devices can additionally support a spread clock.
