OVERVIEW

Overview

ATE9430R is the 4K30 wireless video receiver that pairs with ATE9430T, with output up to 3840 × 2160 @ 30Hz or 120Hz at 1080p. It takes the stream from 5 GHz or the built-in 100 Mbps Ethernet port and drives the display directly through the HDMI connector on the carrier, so loop-out does not apply.

At power-up it reads the display EDID and returns it to the transmitter; keyboards, mice and touch screens on this side go back to the host over the reverse channel. Against the 4K60 ATE9461 the difference is the resolution ceiling; everything else works the same way.

The whole video link is encrypted. TX and RX create their own key at pairing, and video, audio and keyboard/mouse data are encrypted all the way. Devices that are not paired cannot join or decode the picture, which suits meeting rooms, hospitals and factories that do not want video leaking out.

ATE9430R shares its pinout with ATE9430T, so both ends can use one carrier: plug in ATE9430T for a transmitter, ATE9430R for a receiver. That carrier does not take the 4K60 ATE9460 / ATE9461.

Signal Chain

Video goes from transmitter to receiver; EDID and keyboard/mouse data travel back to the host. Wireless and wired links use the same pair of modules.

4K30 vs 4K60

4K30 or 4K60

The two series differ in resolution and in how the transmitter provides loop-out.

Video to RXHDMI loop-out

Apart from resolution and loop-out, the two series share the same size, wireless and Ethernet, link encryption, EDID and KVM behaviour. Their pinouts differ, though, so carriers are not interchangeable and the series do not cross-pair. Loop-out only concerns the transmitter; receivers drive HDMI directly.

CARRIER BOARD

Carrier Board Design Notes

  1. Keep VBUS between 3.7 and 5.1 V. Step down 12 V, 24 V or USB-C high voltage, allowing at least 1 A per module. Tie all VBUS pins together with 22 μF + 100 nF at the edge connector.
  2. 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.
  3. When TX and RX share one carrier, lay out the HDMI connector, Ethernet and antenna once; ATE9430T makes it a transmitter, ATE9430R a receiver.
  4. For a wired link, connect the Ethernet pairs from the edge connector to magnetics and an RJ45; add a 100 Mbps media converter for fiber.
  5. Leave room for two antennas if you plan on RTL8812CU; D40 and D80 need one.
  6. 4K30 and 4K60 pinouts differ, so this carrier cannot take ATE9460 / ATE9461. Moving to 4K60 later means a new carrier designed for the 4K60 pinout.
  7. Leave N and NC pins open. The module runs warm, so leave airflow or a thermal pad over it.
FAQ

FAQ

Q1Can the ATE9430R 4K30 receiver pair with ATE9460?
No. 4K30 and 4K60 are separate series and do not cross-pair. ATE9430R pairs only with ATE9430T.
Q2Which resolutions does ATE9430R support? What is the 1080p maximum?
Up to 3840×2160@30Hz and 1080p@120Hz, plus 3840×2160@25/24, 1080p@60/50/30, 720p, 576p and 480p. For 4K60 or 1080p 240Hz choose ATE9460 / ATE9461.
Q3Can ATE9430R share a carrier with ATE9430T?
Yes. They share a pinout, so the same carrier is a transmitter with ATE9430T or a receiver with ATE9430R.
Q4Is the link encrypted? Can the video be intercepted?
Yes. TX and RX create their own key at pairing; video, audio and keyboard/mouse data are encrypted end to end, and unpaired devices cannot join or decode the picture. Ethernet and fiber links stay encrypted too.
Q5Does ATE9430R have HDMI loop-out?
The receiver drives HDMI directly, so loop-out does not apply. For more screens, add a splitter after the output or use one-to-many with another ATE9430R.
Q6How far does the 4K30 receiver reach?
It depends on the Wi-Fi module, not the resolution: AIC8800-D40 30-100 m (1T1R), AIC8800-D80 100-300 m (1T1R), RTL8812CU 300-1000 m (2T2R, two antenna positions on the carrier), all line-of-sight. Over Ethernet through switches about 500 m, and 10 km or 20 km+ with a 100 Mbps fiber converter.
Q7Can you build wireless display receivers or signage receivers OEM / PCBA with ATE9430R?
Yes. We can supply ATE9430R modules for your own carrier board, or design the carrier to your form factor and interfaces and handle ODM development and PCBA production, including white-label OEM. Start with the ATE946X-KIT to validate link and range.
