XDR6080拆机

TP-LINK XDR6080 disassembly, the memory increased, the most powerful 2.4G chip

Spread the love

The XDR6080 was initially listed for pre-sale when I had two questions, one is whether the CPU will be another, the second is the 2.4G chip will not be QCN9074, QCN9024. everything to disassemble the machine shall prevail. Not to say so much, the last dismantling XDR5480 took a lot of time to look up information and do some network port speed measurement, this time a little simpler, because some already have a good idea.

The shell mold and XDR5480 the same, only 2 additional root antenna, 2.4G more 2 streams well. The outer box is also the same so the packaging is not shot.

This time, the power supply power increased to 12V/3A (XDR5480 is 12V/2.5A), the power supply power enough, because the need to power an additional wireless chip, so the power supply power increase a little is necessary.

Actual measurement XDR6080 standby power is 10.8W (no module inserted), higher than the XDR5480 almost 3W.

The interface on the back of the body is also the same as XDR5480.

The silkscreen on the bottom of the body: AX6000 dual-band, TL-XDR6060 Easy Show Turbo Edition.

Open the demolition, very tight, there are a few clips on the glue fixed, and fear of too much force and broken, so very careful, so it can not be dismantled, must be a miracle of force, really too hard, the group network “easy to show” button broken.

Unpacking the shell looks like.

The antenna layout for 2.4G and 5G is as follows.

Completely disconnected, when you need mesh networking just take a screwdriver and poke it in. When doing the main route networking, I remember that the main route does not need to press this key, only the one to be networked. It doesn’t have much effect on the broken button.XDR6080拆机

Remove the two motherboard fixing screws and turn the motherboard over to look at the back. The heatsink on the back is a bit larger than the XDR5480.

XDR6080拆机

After taking out the screws on the heatsink, take it off, there is white thermal grease on the back of the motherboard, this range is the front of the motherboard on the FEM chip, to help conduct heat to the back to dissipate heat. the front of the FEM chip is not suitable for covering the thermal material, will affect the wireless power, so most of them are through the back to dissipate heat.XDR6080拆机

See a shield, continue to remove the shield, there is no chip inside, there is a piece of thermal conductive silicone pad.

XDR6080拆机

After looking at the back of the motherboard, now look specifically at the front of the motherboard.

Take away the heatsink from the front of the motherboard.

XDR6080拆机

There are shields of the same size on both sides under the motherboard, is it possible to determine the wireless chip used in dual-band is the same?

Quick hands and anxious feet to remove all shields:.

XDR6080拆机

Look at the antenna interface next to the silkscreen will know that the left side of the above figure is 2.4G RF circuit, the right side is 5G RF circuit.

Look at the 2.4G wireless chip is what model it.

XDR6080 2.4G wireless chip model is QCN9074, it can work in 5G can also work in 2.4G, change the ART can. Is it not?

In 4x4mimo, 1024-QAM, 40MHz bandwidth, the maximum rate of 1147Mbps, plus 4804Mbps of 5G, so this XDR6080’s wireless specifications are AX6000.

QCN9074

Also, because QCN9074 and QCN9024 support 4096-QAM (4K-QAM), the 2.4G rate is 20% higher when the phone also supports that property. (4096-QAM can be supported only at 2x2mimo)

At 2x2mimo, 4096-QAM, 40MHz bandwidth, the maximum rate of 688Mbps, wow, this rate is very auspicious ah. The following is the wireless connection rate shown by the system after connecting XDR6080’s 2.4G with Xiaomi 11 phone.

XDR6080 2.4G 688

2.4G FEM chip model is QPF4288, the same as XDR5480.Q{F4288

The parameters of QPF4288 are as follows.

2400-2500 MHz
POUT = +17 dBm HE40 -47dB Dynamic EVM
POUT = +22 dBm HE40 -43dB Dynamic EVM
POUT = +24.5 dBm MCS9 HT40 -35dB Dynamic EVM
POUT = +26 dBm MCS7 HT20/40 -30dB Dynamic EVM
POUT = +28 dBm MCS0 HT20 Spectral Mask Compliance
Optimized for +5 V Operation
33 dB Tx Gain
1.7 dB Noise Figure
15.5 dB Rx Gain & 7 dB Bypass Loss
>10dB 5 GHz Rejection on Rx Path
Integrated RF Power Detector Coupler as well as DC Power Detector

It is a high power FEM.

The 5G chip is very much not in doubt, it must be the QCN9074.

Maximum wireless rate of 4804Mbps at 4x4mimo, 1024-QAM, 160MHz bandwidth.

Maximum wireless rate of 2882Mbps at 2x2mimo, 4096-QAM, 160MHz bandwidth.

QCN9074

5G FEM chip model is QPF4588, also the same as XDR5480.

The parameters of QPF4588 are as follows.

5150 – 5925 MHz
POUT = +16dBm MCS11 HE80 -47dB Dynamic EVM
POUT = +18dBm MCS11 HE80 -43dB Dynamic EVM
POUT = +23dBm MCS9 VHT80 -35dB Dynamic EVM
POUT = +24dBm MCS7 HT20/40 -30dB Dynamic EVM
POUT = +26dBm MCS0 HT20 Spectral Mask Compliance
Optimized for +5 V Operation
33 dB Tx Gain
2 dB Noise Figure
16 dB Rx Gain & 7 dB Bypass Loss
30 dB 2.4 GHz Rejection on Rx Path

High-powered 5G FME chip.

Since there are two QCN9074 chip, the memory can not be 256MB it, although serving you technology, but can not break the physical limits of ah. Each QCN9074 to occupy at least 67MB of memory ah (I dreamed when someone told me this number). Why does this wireless chip also occupy memory ah? Because it has its own built-in core processor, which requires memory. It is a complete wireless chip, it does not need the CPU to provide support for its operation, what support for how many spatial streams, in it does not make sense. Nothing to do with the CPU, I think!

Memory model is ESMT M15T4G16256A, capacity 512MB, good, finally use 512MB memory.

Flash memory model is MT25QU128, capacity 16MB.

CPU model is still IPQ5018 (exclusive silkscreen IPQ0518), dual-core 1GHz, integrated single-core 12-thread NPU, A53 architecture, there are two PCIe 2.0 bus, and two QCN9074 wireless chip is connected with this bus.

XDR6080拆机

The IPQ5018 also integrates 2x2mimo 2.4G wireless, but it is not needed here, so the CPU and memory chips do not have a metal shield like the XDR5430 and XDR5480. Through the XDR6080 disassembly, I finally obvious why the two units plus so strange shield.

The picture below shows the XDR5480 CPU shield design. Why BCM6750, 6755 did not do so? Again, it’s hard for me to understand.

The switch chip model is RTL8367SC, and some people say that this switch chip is new and can support two SGMII+ (2.5Gbps), I don’t know if it is true.

XDR6080拆机

The metal cover below is just an electrical interface in an SFP package, with no chip inside, just an interface. Depending on the module you plug in, you can plug in an optical port module or an electrical port module with a maximum rate of 2.5Gbps.

Power supply, more than XDR5480 a 16V 470uf capacitor: (silver)

So far XDR6080 disassembly is finished.

XDR6080拆机

The following pile is the debris of clips that fell out when removing the shell.XDR6080拆机

To a chip summary chart.XDR6080拆机

Finally installed back into the machine, set up a flip in the downstairs D point for a simple 5G speed test, basically the same as the XDR5480 (300 megabit broadband, routing in the upstairs)XDR6080拆机

5G signal is very strong.

I can guess what chip is going to be listed tri-band XTR10280. It is the same CPU as the XDR6080, the same two QCN9074, supplemented by two 2.4G FEM chip, and then supplemented by eight media filters, it can become a tri-band router: AX10200

XTR10280

However, HF 5G2 has to support 160MHz to work, which requires the use of 100, 104, 108, 112 and 116 channels, which are not open in the Chinese region. The solution is to get a transmission area option to select the region of use.

Similarly, another tri-band XDR7880, also need to do so. Because the low frequency is 4×4 4804Mbps, plus 2×2 2.4G 574Mbps, multiplying the next 2 streams of 5G must be sporting 160MHz to reach 2402Mbps.(7800≈4804+574+2402)

This XTR7880 is equal to the Avenue XDR3060 plus a QCN9074 to achieve. And XDR3060 still do not know what chip, only know that 5G support 2x2mimo 160MHz.

For easy viewing, I list the XDR5480 and XDR6080 and two other hardware configurations to compare.

配置对比

If you care about 2.4G signal and have many 2.4G devices to connect, this XDR6080 is perfect for that.

The XDR5480 can also choose this one if you mind that it only has 256MB of memory, but the XDR5480 can be turned on in high-bandwidth mode (more than 255 units), which is 256MB of memory for you to use, so there should be no problem.

At present, the XCR6080 has not updated its firmware to support the aggregation function, the XDR5480 updated, there may be differences between the two hardware, it takes time to do the adaptation of the firmware.
