OVERVIEW

Overview

ATE9430T is a 4K30 wireless video transmitter, up to 3840 × 2160 @ 30Hz or 120Hz at 1080p. Compared with the 4K60 ATE9460 there are two differences: the resolution ceiling is 4K30, and the HDMI loop-out is built into the module, so one more HDMI connector on the carrier feeds a local monitor without a splitter chip.

The rest matches the 4K60 version: 22 × 45 mm with an 80-pin edge connector, H.265 encoding, 5 GHz wireless plus a built-in 100 Mbps Ethernet port, EDID return and a KVM reverse channel.

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.

ATE9430T and ATE9430R share one pinout, so the transmitter and receiver can use the same carrier board: one design, two products, half the prototyping and stock. 4K30 and 4K60 pinouts differ, so this carrier does not take ATE9460 / ATE9461.

SIGNAL CHAIN

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.

Fallback EDIDBuilt-in default EDID while the link is down, so the source always outputs

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. For a local monitor, route the loop-out signals from the edge connector to a second HDMI connector. Loop-out runs up to 4K30 with no splitter chip; the loop-out pins come with the carrier reference design.
  4. When TX and RX share one carrier, lay out the HDMI connector, Ethernet and antenna once; ATE9430T makes it a transmitter, ATE9430R a receiver.
  5. 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.
  6. Leave room for two antennas if you plan on RTL8812CU; D40 and D80 need one.
  7. 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.
  8. Leave N and NC pins open. The module runs warm, so leave airflow or a thermal pad over it.
FAQ

FAQ

Q1ATE9430T vs ATE9460: how do I choose between 4K30 and 4K60?
Two points. Resolution: ATE9430T tops out at 4K30 and 1080p 120Hz, ATE9460 at 4K60 and 1080p 240Hz. Loop-out: ATE9430T has 4K30 loop-out on the module, ATE9460 needs a splitter chip on the carrier. Size, wireless and Ethernet, encryption, EDID and KVM are essentially the same, but the pinouts differ, so carriers are not interchangeable.
Q2How is the loop-out wired on a wireless HDMI transmitter with loop-out?
The loop-out is done inside ATE9430T. Route the loop-out signals from the edge connector to a second HDMI connector and plug in the local monitor, up to 4K30, with no splitter chip. The loop-out pins come with the carrier reference design.
Q3Can the 4K30 transmitter and receiver share one carrier board?
Yes. ATE9430T and ATE9430R share a pinout, so one carrier PCB becomes a transmitter or a receiver depending on the module, saving on prototypes and stock. The 4K60 ATE9460 / 9461 cannot do this.
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.
Q5How far does the 4K30 wireless video module 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.
Q6If I move to 4K60 later, does the carrier change?
Yes. Switch to the ATE9460 / ATE9461 pair and redesign the carrier for the 4K60 pinout; the series do not share carriers or cross-pair.
Q7Can you build loop-out transmitters or lecture-capture senders OEM / PCBA with ATE9430T?
Yes. We can supply ATE9430T 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.
