Q1How do I choose a wireless HDMI module? What is the difference between 4K60 and 4K30?
Pick the model by resolution, then the Wi-Fi module by range. For 4K60 use ATE9460 (TX) + ATE9461 (RX): up to 3840×2160@60Hz and 1080p@240Hz. For 4K30 use ATE9430T + ATE9430R: up to 3840×2160@30Hz and 1080p@120Hz. The two series differ only in resolution and TX loop-out (ATE9430T has 4K30 loop-out on the module; ATE9460 needs an HDMI splitter chip on the carrier for 4K60). Both are 22×45 mm 80-pin edge-connector modules, but the pinouts differ, so carriers are not interchangeable.
Q2What range does the wireless video module reach? Which option for 30 m, 100 m, 300 m or 1 km?
Range comes from the Wi-Fi module, not the resolution; every tier runs 4K60. AIC8800-D40 covers about 30-100 m (one antenna, 1T1R), AIC8800-D80 about 100-300 m (one antenna, our default), and RTL8812CU about 300-1000 m (two antennas, 2T2R, so the carrier needs two antenna positions). These are line-of-sight figures; antenna placement, obstacles and co-channel interference change them, so test samples before production.
Q3What is the latency of the wireless HDMI link at 4K60 and at 1080p high refresh?
Per the ATE9460 / ATE9461 datasheets: about 100 ms end to end at 4K60 and about 33 ms at 1080p 240Hz / 120Hz. Video is H.265 with a bitrate that adapts to the channel, up to 60 Mbps. For latency-sensitive uses (gaming, drone control, KVM) run 1080p at high refresh. Latency for the 4K30 series is still to be measured.
Q4Which resolutions and refresh rates are supported? HDR and 10-bit?
The 4K60 series supports 3840×2160@60/30/25/24, 2560×1440@60, 1920×1080@240/165/144/120/60/50/30, 1600×1200@60, 1280×720@60/50, 720×576@50 and 720×480@60; the 4K30 series tops out at 3840×2160@30 and 1080p@120. RGB 4:4:4 and YCbCr 4:4:4 / 4:2:2 / 4:2:0 are detected automatically, 8-bit and 10-bit are supported (10-bit up to 4K30 on the 4K60 series), and HDR10 static metadata and HLG pass through.
Q5Does the module support EDID pass-through and HDCP?
Yes. The RX reads the full display EDID and returns it over the link; the TX presents it to the source, so the source outputs what the screen supports, with no black screen, missing audio or downscaling. While the link is down the TX presents a built-in default EDID. HDCP 2.3 / 1.4 is supported with automatic fallback to 1.4. The module works as an HDCP repeater; the end-product maker needs its own HDCP license.
Q6Which USB devices work in a wireless KVM design? Keyboard, mouse, touch screen, barcode scanner?
USB HID devices such as keyboards, mice, touch screens and barcode scanners plug into the RX and are passed back to the host on the TX side, appearing as local USB devices with no drivers. KVM data runs over both the wireless and wired link. Non-HID devices such as flash drives and cameras, and game controllers, have not been verified; test with samples if your project needs them.
Q7Can the module run over Ethernet and fiber? How is HDMI over fiber built?
Yes. All four 4K60 / 4K30 models have a 100 Mbps Ethernet PHY on the module with ETX± / ERX± pairs on the edge connector; add magnetics and an RJ45 on the carrier. One cable segment is about 100 m, about 500 m through switches or routers, and a 100 Mbps fiber converter takes it to 10 km or 20 km+. The wired mode carries video, audio and KVM and stays encrypted.
Q8Can the wireless video be intercepted? How is the link encrypted?
No. Every model encrypts the video link with a key created when TX and RX pair. Video, audio and keyboard/mouse data are encrypted all the way, and unpaired devices cannot join or decode the picture. The link stays encrypted over Ethernet and fiber too.
Q9Can one transmitter feed several receivers?
Yes, one TX can broadcast to several RX units, which suits on-set monitoring and digital signage. How many receivers and at what quality depends on distance and interference, so test with samples for your project.
Q10What are the power requirements and how should the carrier power be designed?
Single VBUS rail 3.7-5.1 V, typically 5.0 V; above 5.1 V destroys the module. ATE9460 draws 500-800 mA (2.5-3.8 W); ATE9461 500-600 mA (2.3-2.8 W); the 4K30 series is still to be measured. Budget at least 1 A per module, tie all VBUS pins together, place 22 μF + 100 nF at the edge connector, and keep ripple under 50 mVpp. Step 12 V, 24 V or high-voltage USB-C down with a DC-DC converter first.
Q11How should the carrier PCB be designed and how should HDMI be routed?
Route the four TMDS pairs at 100 Ω differential, intra-pair skew under 5 mil and inter-pair under 20 mil, with no layer changes or split crossings and 3W spacing from key, LED and I²S traces. No test points in the edge-connector area, leave N / NC pins open, and connect every G / GND / NG pin to the ground plane. Leave two antenna positions if you use RTL8812CU. We supply the DEMO schematic, PCB reference, pinout and DXF / STEP models, or we can design the carrier board for you.
Q12Can TX and RX share a carrier board? Are 4K30 and 4K60 pin-compatible?
ATE9430T and ATE9430R (4K30) share one pinout, so one carrier becomes a transmitter or a receiver depending on the module. ATE9460 and ATE9461 (4K60) differ (VBUS, for example, is on pins 53/55/57 on ATE9460 and 18/20/22/24 on ATE9461) and need separate carriers. 4K30 and 4K60 are not pin-compatible either; only the package size matches, so carriers cannot be shared and the series do not cross-pair.
Q13What is the module size and package? Will it fit a compact product?
22.0 × 45.0 mm (±0.15 mm), 80-pin edge connector at 0.5 mm pitch, 0.80 mm PCB, top components up to 1.1 mm and bottom up to 2.1 mm, held by an M2 screw at the far end. It fits presentation dongles, portable monitors, docks and in-car boxes. Ask for DXF drawings and STEP models to check clearances during mechanical design.
Q14Can I build USB-C or DisplayPort wireless casting with this module?
Yes. The module video interface is HDMI: for USB-C input add a USB-C (DP Alt Mode) to HDMI chip on the TX carrier, for DP input a DP to HDMI chip, and for a DP display on the RX side an HDMI to DP chip. USB-C casting needs a source whose USB-C port outputs video (DP Alt Mode). Whether the product reaches 4K60 depends on the converter chip.
Q15How are modules paired? Does each unit need pairing in production?
No. TX and RX ship paired and link at power-up, so the production line only runs a power-on test. To re-pair on site, hold KEY for 5 s (LED blinks fast); when paired the LED stays on and the RX shows an OSD with pairing and key info. Holding KEY for 25 s or more resets the module and clears the SSID, key and pairing.
Q16Are you a wireless video module manufacturer? Do you do OEM / ODM and PCBA?
Yes. Anlya Technology in Shenzhen develops its own 4K60 / 4K30 wireless HDMI modules. We can supply modules only, or design the carrier board, develop the product (ODM) and build PCBA for you: wireless presentation systems, wireless KVM extenders, HDMI over fiber, USB-C casting adapters, wireless CarPlay boxes and more. White-label OEM is available.
Q17What are sample and lead times? Is there an evaluation board?
Stock models ship in 3-5 business days; custom firmware takes 2-3 weeks. Start with the ATE946X-KIT (paired TX + RX, DEMO carriers, antennas, USB-C power and HDMI) to check link, range and picture before designing your board. Volume and PCBA lead times are confirmed per order.
Q18What certifications does the module have? Does the end product still need certification?
Regulatory settings are flashed per sales region (CN / FCC / CE / TELEC / KC), so state the region when ordering; certification documents are provided per region on request. The end product still needs its own certification for the target market. Check with us before changing antenna type, gain or placement, as that may require retesting.
Q19Do you have 8K wireless video and UVC to HDMI products?
ATE9860 (TX) / ATE9861 (RX) are 8K30 wireless video modules in development, with the same button pairing and link encryption. ATE9946 converts a USB UVC camera to HDMI output at up to 4K60 and is also in development. Specs and launch dates are not fixed yet; contact us early if you have a project.
Q20What else can you develop besides wireless video?
Video codecs, AI video processing, real-time human and object detection, speech noise suppression and offline recognition, plus in-car instrument UI and wireless CarPlay / Android Auto casting, all developed per project with PCBA.
