hello everyone

today let's learn about CNVI Bus

CNVI Bus is Intel's new dedicated connection interface

for Wifi and Bluetooth

it can reduce costs and simplified its wireless modules

the current wireless network card uses the m.2

interface the Wi Fi communicates with the chip set

through the Pcie Time one bus

Bluetooth communicates with the chip set

through USB bus

the network device in the CNVI bus

which is the Wi Fi module

most of its functions are integrated into the chipset

only the signal processing

analog and RF functions remain on the external

upgradeable companion RF module

therefore

the CNVI bus is the bus that connects the chipset

and the Wi Fi and blue modules

from this architecture diagram

we can see that the WT part of the CNVI bus

is the sending circuit

that belongs to the chipset

the chipset sends data to the Wi Fi module

through these 6 lines of W t

W R this part is the receiver circuit of the chipset

the chipset receives the data transmitted by Wi Fi

through these 6 lines

the lines of RGI and BRI

are connected to the Bluetooth Moujou

used by Bluetooth

the advantage of CNVI bus is that it no longer

occupies the Pcie channel

provided by the chipset

pushing motorboard makers to adapt integrated

wireless network cards

this is the CNVI bus
