Clock and Timing

Analog Devices provides discrete rate, multirate, and continuous tuning clock and data recovery ICs for equipment designs, including metro, long haul, DWDM, and FSO applications. ADI CDRs allow easy integration into protocol agnostic applications, automatically locking onto incoming data streams at any rate between 12.3 Mbps to 2.7 Gbps without the aid of a reference clock while reporting the acquired data rate over the I2C interface.

Analog Devices offers ultralow jitter clock distribution and clock generation products for wireless infrastructure, instrumentation, broadband, ATE, and other applications demanding sub picosecond performance. ADI clock products are ideal for clocking high performance analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). ADI clock ICs integrate PLL cores, dividers, phase offset, skew adjust, and clock drivers in small chip scale packages.

Analog Devices’ diverse portfolio of counters, timers, and delays enables a variety of basic circuit building blocks. These small, low power devices provide higher accuracy and lower component count over traditional discete implementations and require no programming or a microcontroller.

Analog Devices’ world-leading direct digital synthesis ICs incorporate features such as on-board comparators, RAM, PLLs, mixers, and registers. ADI direct digital synthesis products provide fast acquisition, highly accurate PSK and FSK modulation or high precision tuning resolution, among other benefits. They are an ideal synthesizer solution in applications where precise or agile frequency and phase control is required, such as systems for communications, test equipment, and radar.

Analog Devices offers highly reliable and high precision crystal oscillator modules. Our crystal oscillator modules offer the most precise timing solutions available with industry-leading accuracy over temperature, frequency stability, and best phase noise and jitter feature sets. We provide voltage controlled and temperature compensated crystal oscillators.

ADI’s industry leading phase locked loop (PLL) synthesizer family features a wide variety of high performance, low jitter clock generation and distribution devices. The extensive, ever growing phase locked loop family now includes over 100 products, optimized for high data rate, low jitter clocking applications. The portfolio features PLLs, PLL/VCOs, and distribution chips, designed for clocking applications which require synchronization, clock distribution, and phase noise performance. Analog Devices has over 25 years of experience in design and test of industry leading phase locked loop integrated circuit products. With the industry's widest portfolio of PLL products, we can cover virtually all your PLL needs. Analog Devices’ fully integrated and ready to use translation loop (also known as an offset loop) System in Package (SiP) are used for frequency synthesis in highly jitter sensitive applications, and reduce board space and complexity compared to traditional discrete translation loop solutions designed on a PCB. Time to market is significantly reduced by taking advantage of this highly integrated solution with in-package circuitry and enhanced isolation that attenuate spurious components. Analog Devices’ translation loop solutions provide a frequency synthesis solution for engineers designing highly competitive systems.

Real-time clock (RTC) ICs are used in electronic circuits to keep track of time relative to the “real” world. Maintaining accurate time is critical, especially under periods of severe system stress or when the power of the main device is off. During these times, RTC ICs must provide robust performance and will often draw power from an auxiliary battery or supercapacitor. As expected, power consumption is a key factor in most real-time clock designs, in addition to accuracy, ruggedness, and small package size. Most modern RTCs reduce the number of pins required by supporting a serial interface. We offer a wide variety of highly accurate, low power, small package, and microelectromechanical systems (MEMS)-based real-time clocks to suit any of your solution needs.

Analog Devices silicon oscillators are frequency programmable via pin-strapping, or through the resistor connection or serial interface (SPI or I²C). These solid-state clocks are well-suited for general-purpose usage, such as PGAs, ASICS, microprocessors, or UARTS, and they operate from 1 kHz to 170 MHz. Silicon oscillators are also ideal switching regulator clocks as they provide synchronization and EMI reduction (via spread spectrum).
