In the field of high-performance mixed-signal semiconductor solutions, IDT (Integrated Device Technology, Inc.; NASDAQ: IDTI) has always been at the forefront of technology. Today, IDT announced the launch of a new low-noise timing chipset for wireless base transceiver station (BTS) radio frequency card applications, further optimizing their technology. This chipset not only complements IDT's communications signal chain product line, but also provides engineers with efficient tools to solve phase noise-related challenges and build high-performance wireless communications systems.
The highlight of the IDT 8V19N4xx chipset is its inclusion of a JESD204B-compliant radio frequency phase-locked loop (RF PLL) and clock synthesizer, which enables it to meet the stringent high frequency and low phase noise requirements of 2G, 3G and 4G LTE wireless infrastructure Require. Leveraging IDT's FemtoClock® NG technology, this chipset excels in reducing phase noise, enabling higher accuracy and lower distortion for analog-to-digital and digital-to-analog converters (ADCs/DACs) in the system. This not only improves signal transmission integrity and reception sensitivity, but also improves data throughput by reducing the bit error rate (BER). In addition, the reduction in noise in the RF signal path helps base station developers reduce the need for system filters, thereby reducing cost and complexity.
Christian Kermarrec, vice president and general manager of IDT's Timing and Synchronization Division, said: "We are well aware of the adverse effects of noise on the RF signal chain, and therefore developed this timing chipset. It not only provides system engineers with solutions to noise A new tool for problem solving, it also has several key features, including JESD-compliant clocking capabilities and integrated clock jitter attenuation, that can be easily integrated with customer-specific architectures. This new timing device is not only our industry-leading timing product series, and also broadens the application scope of other products, including wireless infrastructure, data converters, data compression, RapidIO® and RF signal chain products."
The IDT 8V19N4xx chipset also has the ability to generate the synchronous and highly configurable clock and SYSREF signals required for JESD204B applications. This means customers can use a highly flexible and cost-effective standard timing chip instead of multiple phase-locked loops, synthesizers and buffers. At the same time, its integrated clock jitter attenuation feature simplifies system design and reduces overall system cost by supporting low-cost, low-frequency external VCXOs.
Regarding product availability, IDT 8V19N4xx devices have now entered the sample delivery stage for qualified customers and are packaged in standard VFQFPN. Its flexible combination of RF phase-locked loop and high-frequency synthesizer further increases the flexibility and diversity in applications. Through this innovation, IDT once again proved its leading position in the field of wireless base station radio frequency technology, providing strong technical support for the future development of communication infrastructure.
