The first Realtek RTL8157 5Gbps Ethernet to USB 3.2 adapters are now available for $35

WisdPi WP-UT5 is the first Realtek RTL8157 5Gbps Ethernet (5GbE) to USB 3.2 adapter to make it to market, following the launch of Realtek RTL8126 5Gbps Ethernet PCIe and M.2 adapters last June, and the announcement for both the RTL8126 and RTL8157 chips at Computer 2023 last year. While the RTL8126 dongles and cards are fairly cheap at around $16 on average and as low as $12, the WisdPi WP-UT5 is sold at a premium for about $35 on AliExpress, but we can expect the price to down come as more companies introduce 5GbE to USB 3.2 adapters. For reference, the 2.5GbE variants based on RTL8156(BG) can be had for about $20 on Amazon. WisdPi WP-UT5 specifications: Chip – Realtek RTL8157 USB USB 3.2 Type-C female port A-C and C-C cables to support hosts with USB Type-C or Type-A ports Ethernet 10/10/100/2500/5000 Mbps Ethernet Supports 5G Lite (2.5Gbps data rate) […]

Realtek WiFi 7 and WiFi 6 roadmap for routers and clients

We’ve just written about Realtek 5 Gbps Ethernet chips, but the company also has some roadmaps for WiFi 6 and WiFi 7 router chips, and a WiFi 7 client module demonstrated at COMPUTEX 2023. The company’s roadmap include five WiFi 7 router solutions: WiFi 7 BE6500 router with a Realtek 8198DS dual Arm core processor @ 1.2 GHz with an RTL8952AR 2×2 MIMO 5 GHz and 6 GHz chip, RTL8902A 2×2 2.4 GHz chip, and an RTL8221B 2.5GbE PHY WiFi 7 BE9400 router with a Realtek 8198DS dual Arm core processor @ 1.2 GHz with an RTL8952AR 2×2 MIMO 5 GHz chip, RTL8902A 2×2 2.4 GHz chip, an RTL8934AR 4×4 MIMO 6 GHz chip, and an RTL8221B 2.5GbE PHY WiFi 7 BE3400 router with a Realtek 8198DS dual Arm core processor @ 1.2 GHz with an RTL8952AR 2×2 MIMO 5 GHz chip, and an RTL8221B 2.5GbE PHY WiFi 7 BE6400 […]

Realtek RTL8126, RTL8157, and RTL8251B 5Gbps Ethernet solutions showcased at COMPUTEX 2023

I only upgraded my local network to 2.5 Gbps Ethernet last year, but 5 Gbps Ethernet is soon coming to the home as shown by Realtek at COMPUTEX 2023 with demonstrations of their RTL816, RTL8157, and RTL8251B 5GbE chips that were initially unveiled at CES 2022. The RTL8126-CG is a PCIe 3.0 x1 to 5GbE controller offered in a QFN56 8x8mm package that succeeds the RTL8125 chips, the RTL8157-CG is a USB 3.2 Gen2 to 5Gbps Ethernet controller in a 8x8mm QFN68 package providing an update the RTL8156(B)/(BG) 2.5GbE USB controllers, and the RTL8251B-CG is a single-port “PHYceiver” in a 8x8mm QFM56 package. All support 10/10/100/2500/5000 Mbps links and consumes under 1.5 watts, against 0.7W for 2.5 GbE networking. The same Cat5e cables can be used at the higher speed. The company did not just come with some slides to show and also showcased some test boards for each chip […]

Realtek RTD1319D STB processor supports 4K H.266 and AV1 video decoding

Realtek RTD1319D is the first set-top box processor to support H.266 (aka Versatile Video Coding) video compression standard. The new SoC also provides a GPU with 10-bit graphics, support for multiple Conditional Access Systems (CAS), and HDMI 2.1a video output capable of up to 4Kp60 with HDR. One would have thought the royalty-free AV1 video codec might have killed licensed codecs such as H.266, but it’s clearly not the case, since Realtek decided to launch the RTD1319D processor with the new codec, and the primary reason may be because the H.266/VCC codec was added to the DVB specification last February for both 4K (3840×2160) and 8K (7680×4320) resolutions. Realtek RTD1319D preliminary specifications: CPU – Quad-core Arm processor GPU – Unnamed GPU with 10-bit graphics Video Output – HDMI 2.1a up to 4Kp60 HDR Video Codecs 4Kp60 Versatile Video Coding (VVC/H.266) 4Kp60 AV1, H.265 Tuner support Built-in DVB demodulators Multiple TS […]

Ai-Thinker BW16 is a dual-band WiFi & Bluetooth 5.0 IoT module (Sponsored)

Ai Thinker BW16 dual-band WiFi BLE 5.0 module

Many users prefer the ESP32 when implementing WiFi & Bluetooth into their IoT projects. But Ai-Thinker BW16 offers dual-band WiFi 4 & Bluetooth 5.0 connectivity through Realtek’s RTL8720DN chipset which may provide more reliable connectivity where the 2.4 GHz band is crowded. The module integrates an Arm Cortex-M4F compatible high-performance MCU, an Arm Cortex-M0 compatible low power MCU, WiFI 802.11 a/b/g/n, MAC, Bluetooth and RF baseband, and provides a set of configurable GPIO ports to control peripheral devices. BW16 module One significant difference between BW16 and ESP32 module is that it has two serial port interfaces, so attention should be paid to the wiring of the UART interfaces. The following diagram shows the two serial interfaces of the BW16 module. One of the module serial interfaces is used to send and receive AT commands to control connectivity from a host processor or microcontroller, while the other serial port is used […]
