The MS1130 and MS1150 oscillators from Mixed-Signal Devices use digital architecture to produce low-noise, low-jitter clock signals. Mixed Signal Devices (MSD) has introduced two clock generators designed for synchronizing signals in datacenters, telecom networks, and other digital communications systems. The MS1130 (10 MHz to 1 GHz) and MS1150 (20 MHz to 2 GHz) use a…
TXCO operates at 1.2 V
Aker Technology USA has released the TX21ED Series, a 1.2V Temperature Compensated Crystal Oscillator (TCXO) that is the ultimate choice for next-generation low-power applications in an era of energy-efficient and high-performance electronics. The ultra-low power TX21ED Series meets the demands for frequency stability while significantly reducing power consumption, designed for wearable devices, IoT sensors, and mobile…
OCXO holds network timing for up to 8 hours
SiTime Corporation announced the SiTime Epoch Platform, designed to solve the most complex timing issues in electronics and disrupt 100-year-old quartz-based technology. The SiTime Epoch Platform is a MEMS-based, oven-controlled oscillator (OCXO) that delivers an ultra-stable clock to data center and network infrastructure equipment, unlocking a cumulative $2 billion served addressable market (SAM) in the next decade.…
Use TTL or analog signals to program voltage-controlled oscillators
Fairview Microwave has expanded its product line with 15 new analog and TTL programmable voltage-controlled phase shifters. These cutting-edge products cover broad frequency bands ranging from 0.5 GHz to 33 GHz, including the popular market bands VHF, L, S, C, X, Ku, K, and Ka. The new release includes eight models of voltage-controlled analog attenuators…
Open RAN networks pass the time
Network elements must meet certain frequency, phase, and time requirements to ensure proper end-to-end network operation. Synchronization architectures defined by the O-RAN alliance dictate how Open RAN equipment can meet these requirements. Open RAN continues to attract interest from service providers looking to reduce cost, improve competition, and drive technology innovation. The desire for a…
IMS 2022 video: Analog Devices
Analog Devices demonstrated its ADF4377 Microwave Wideband Synthesizer with Integrated VCO at IMS 2022.
Oscillator shrinks size and power
The Elite X Super-TCXO from SiTime provides stable timing from 1 MHz to 60 MHz for edge computing, vehicles, and cellular base stations.
Timing IC combines functions for Open RAN
Microchip’s ZL30735 integrates eight DPLLs, five low-output jitter synthesizers, and an IEEE 1588-2008 protocol stack. The splitting of radio access network functions creates an Open RAN that promises greater innovation and features in 5G networks. Splitting the traditional baseband unit into radio units (RU), distribution units (DU) and centralized units (CU) brings timing issues not…
Meet timing requirements in 5G networks
5G needs tighter timing requirements than do 4G networks. The timing must perpetuate from the radio throughout the telecom network core.
How timing sources synchronize open RAN networks
IEEE 1588 PTP and SyncE protocols keep radio units, switches, and distribution units in sync.
