Si89xx Isolated Amplifier and Delta-Sigma Modulators

Skyworks Solutions announced the availability of its next-generation Si89xx isolated analog amplifiers, voltage sensors and delta-sigma modulator (DSM) devices to improve charging times for electric vehicles (EVs). Skyworks’ new family, which includes Si8921Si893x and Si894x, will help to shorten recharge time for EVs. and offers broader industry applications and improvements for solar inverters and wireless charging.

Thsse devices provide accurate isolated current and voltage measurement with very low drift across temperature. Based on robust isolation technology, the new Si89xx family provides flexible voltage, current, output and package options to help developers reduce BOM cost and shrink board space for a wide range of industrial and green-energy applications including electric vehicle (EV) battery management and charging systems, dc-dc converters, and motor, solar and wind turbine inverters.  Early customer interest has been exceptional with hundreds of customers sampled and design wins across top automotive EV and industrial customers.

Si89xx products provide accurate, precise measurement readings of the current and voltage involved in the operation of power control systems, including 75 kV/µs immunity to fast transients and accuracy over temperature. This minimizes loss of power and makes the system more efficient, allowing for charging devices to more swiftly transfer power. This enables charging improvements for the EVs and industrial applications such as wireless infrastructure, data centers and wired communications.

Skyworks’ Si89xx consists of the Si8921 isolated analog amplifiers, the Si893x isolated voltage sensors and the Si8941/6/7 isolated DSM devices. These devices are optimized for voltage or shunt-current sensing and provide typical offset error as low as ±40 µV and ±0.1% gain error. Additionally, offering a typical offset drift as low as ±0.5 µV/˚C and typical gain drift as low as –4 ppm/˚C, allows for exceptional accuracy across temperature. As a result, Si89xx devices can offer one of the industry’s highest signal-to-noise ratios (SNR) – up to 90 dB.

The Si89xx family offers the following options:

  • Current or voltage-optimized devices with single-ended, differential or DSM output
  • ±62.5 mV, ±250 mV or 2.5 V input ranges
  • A stretched wide-body SOIC-8 package to support 5 kVrms isolation and 8 mm creepage/clearance and a compact narrow-body SOIC-8 to support 2.5 kVrms isolation.

Coilcraft Unveils 0805 Wire-wound Ferrite Beads

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

Above: The Si53301/4-EVB development kit

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.
