In I/O port applications, TESD Series devices meet regulatory requirements including the repetitive application of IEC61000-4-2 (ESD) ±15kV (air), ±10kV (contact), and IEC61000-4-5 (Lightning): 5.5A (8/20μs). These devices also meet 30 KV contact/air requirements for power port applications. In addition, the Series meets all global environmental requirements. The devices’ ultra-low capacitance is essential for ±3.3V or other nominal operating voltage applications operating at high data rates. The ESD protection devices ideally have little to no effect on normal operation while retaining the ability to survive the repeated application of ESD discharges.

The TESD Series is available and in In-stock at Mouser and DigiKey from $0.0848 (depending on part number and volume.)

Powercast

Operating in the lower 600 – 900 MHz frequency bands licensed by mobile carriers, the Powercast cellular-based RF Wireless Charging Platform has unique benefits: Because cellular bands are licensed, or private, they have more flexibility on how much power they can transmit, antenna gain, and bandwidth which enables end devices to charge faster and at greater distances when compared to unlicensed, or public, bands; As cellular service moves increasingly to higher frequencies like 5G to increase data throughput, carriers can monetize their underused low-frequency bands and offer “Power as a Service.”; Ability to simultaneously charge at-a-distance many consumer devices, such as smart home security and automation IoT sensors, TV remotes, keyboards, earbuds, headphones, smart watches, fitness bands, and hearing aids;

The platform combines Sequans’ Monarch 2 GM02S module with a Powercast RF transmitting antenna to send RF over the air to a tiny Powercast PCC110 Powerharvester receiver chip embedded in end devices. The Powerharvester harvests RF out of the air and converts it to DC (direct current) to either power a battery-free device, or charge a rechargeable battery, both of which keep disposable batteries out of landfills.

In the Mobile World Congress demo, a Sequans Monarch 2 cellular modem teams with Powercast’s 700MHz antenna to transmit a 700MHz RF cellular signal to Powercast’s PCC110 receiver and RF-to-DC converter chip, which then powers a battery-free sensor beacon to transmit temperature and humidity data to a gateway or phone.

Each of the new linear ReDrivers allows flexible adjustment of signal integrity parameters, such as equalizer and flat gain, through the various settings available. This mitigates channel loss and extends reach. These devices are transparent to channel link training. In addition, they exhibit ultra-low latency figures (<300ps).

The PI2DPX2020 supports different operational modes for maximum design-in flexibility. These are 20Gbps/40Gbps USB4 Gen3 (x1/x2), 20.625Gbps/41.25Gbps Thunderbolt 4.0 (x1/x2), 10Gbps/20Gbps USB4 Gen 2 (x1/x2), 20Gbps USB4 Gen2/2 lanes of DisplayPort 2.0 and 4 lanes of DisplayPort 2.0. The 4-lane PI2DPX2023 20Gbps DisplayPort 2.0 (UHBR20) ReDriver supports pin strap equalizer and gain parameter control, while for the PI2DPX2063 20Gbps DisplayPort 2.0 (UHBR20), this is achieved via the I2C interface pin.

These new ReDrivers have auto power-saving modes built in. They are supplied in 32-pin W-LGA4528 packages (with 2.85mm x 4.5mm x 0.7mm dimensions) and support an industrial temperature range.

In 5000 piece quantities, the PI2DPX2020 is available at $2.99, the PI2DPX2023 is available at $3.00, and the PI2DPX2063 is available at $2.95.
