Coilcraft Unveils 0805 Wire-wound Ferrite Beads

Posted on by Techtime

Coilcraft announced new release of its 0805PB Series automotive small size wire-wound ferrite beads. The series features robust mechanical structure, and is approved for the automotive applications and harsh environments standard AEC-Q200 Grade 1  (–40°C to +125°C).

Ferrite beads, or ferrite chokes, are used as low pass filters to eliminate high frequency noise while allowing low frequency signals or DC current to pass through a circuit. The noise may come from any number of sources including high-frequency switching noise from a power-supply circuit or RF noise in an RF signal-isolation circuit that must be minimized to ensure both signal integrity and antenna efficiency.

Wirewound ferrite beads also provide lower DC resistance (DCR) and higher current ratings without core saturation, resulting in the highest possible performance in the smallest size

The 0805PB Series offers extremely low DCR that is optimized for high-frequency (up to 1.7GHz) noise suppression on high current power supply lines of up to 4.4 Amps. The new products provide wider spectrum of suppression than traditional ferrite beads, with inductance ranging from 0.1μH up to 3.6μH (±20% Tolerance). It is RoHS compliant , halogen free, and can be stores in wide range of tempertures (–40°C to +140°C).

Skyworks’ Si5332 Clock Family Supports PCIe 6.0

Posted on by Techtime

Skyworks Solutions announced the evolution of its Si5332 family of high-performance clock generators, supporting the industry transition to PCI Express Generation 6 (PCIe 6.0). According to PCI-SIG, new applications including Artificial Intelligence, Machine Learning and Edge Computing are driving the need for higher performance and increased bandwidth interconnects for compute, switching and storage platforms in data centers.

The Si5332 product family supports PCIe 6.0 while maintaining backwards compatibility with older PCIe standards. “PCIe 6.0 is the future of the data center,” said James Wilson, VP and general manager of timing products at Skyworks. “We have qualified our Si5332 family to provide reference timing for the newest PCIe 6.0 applications.”

PCIe 6.0 increases data rates to 64GT/s and enables bandwidths as high as 256Gbps, effectively doubling the performance of PCIe 5.0. This latest upgrade to the PCIe standard ensures the high-speed interconnects used in data center applications do not become a bottleneck and complements the industry’s transition to 400G and 800G Ethernet.

Eye-diagrams for PAM4

Unlike prior generations of the PCIe standard, PCIe 6.0 uses PAM4 modulation to combine two bits into a single symbol with four amplitude levels. This approach doubles the transfer speed but degrades the eye diagram by replacing a single, large data eye with three smaller data eyes. Using a low jitter PCIe reference clock maximizes the PAM4 data eye opening and minimizes bit-error rate, which is necessary for faster transfer speeds.

The Si5332 is ideally suited to replace fixed function oscillators, clocks and buffers with a single IC. The device features Skyworks proprietary MultiSynth fractional divider technology, for better jitter performance. The Si5332 is available in 6, 8 and 12-output options, with support for integrated format/level translation, LVPECL, LVDS, HCSL and LVCMOS, and 1.8-3.3V VDDO operation.

When combined with support for PCIe 6.0, the Si5332 is well suited to operate as a data center clock-tree-on-a-chip, replacing multiple timing components with a highly integrated, high-performance solution. In addition to this Si5332 product announcement, Skyworks announced PCIe 6.0 support in its PCIe Jitter Tool – widely used for measuring PCIe clocks and evaluating compliance to PCIe jitter specs.

Patent Dispute: USPTO Ruled in Favor of VARTA

Posted on by Techtime

The USPTO (United States Patent Office) Trial and Appeal Board ruled in favor of VARTA in an ongoing patent dispute between VARTA  and its Chinese competitor EVE Energy Co., Ltd. The related patent covers aspects of VARTA’s CoinPower microbattery technology. The patent is presently in an infringement lawsuit in the U.S. against EVE Energy. VARTA estimates that USPO decision, “greatly strengthen the patent and the likelihood to prevail in the litigation”.

VARTA provides micro batteries, household batteries, and customer-specific battery solutions for a variety of applications. It offers a wide range of primary Lithium button cell types with a voltage of 3.0 V and capacities from 27 mAh up to 560 mAh. They are used in reliable applications such as Memory Back Up (MBU), Real Time Clock (RTC), clocks, car key applications and more. The batteries appear in various PCB, SMT and wire & connector versions.

Its Lithium Cylindrical Batteries provides power for applications like energy meters, water meters, gas meters, heat cost allocators, medical pipets, sensors and alert systems and home security sensors. Thanks to low self discharge of less than 1 % per year, their operational life reach up to 10 years. The company’s Alkali Manganese Cylindrical Batteries appears also in an Industrial Pro version, for use in mobile equipment such as GPS equipment, pagers, remote controls, clocks and other devices who need powerful energy source for optimum performance.

Knowles announced a new product-line of SLC capacitors and expand its RF Filtering

Posted on by Techtime

Knowles Precision Devices announced that its DLI brand continue to expand its RF Filtering options with newly acquires Lumped Element and Ceramic Resonator Filters to go alongside its SMD high frequency microstrip filters.

DLI is also establishing a range of broadband blocking components under the ‘Xtreme Broadband Blocking Components’ heading. It includes a new line of Single Layer Capacitors – SLC for RF and microwave applications (mmWave). Existing parts, like Opti-Cap, MilliCap, MLC Broadband Blocks and RF Blocking Networks, will be included, as well as new ones. The first of which is the PX range for DC blocking applications up to 40 GHz.

The structure of SLC capacitor is based on a rectangular piece of dielectric material with metallization across the bottom and top of the ceramic. According to the research firm Future Market Insights, The single layer capacitors market is projected to grow at an expected CAGR of 10.9% during the forecast period 2021-2031.

The increase in demand of SLC capacitors is driven by their high operating voltage of up to 10 kilovolts (kV), high stability and low losses for resonant circuit application. These capacitors have better mechanical durability as compared to multilayer ceramic capacitors and are used for very high frequency applications.
