Current trends and recommended frequency for automotive SENT interface usage

What is the trend for SENT interface which is been used nowadays, How fast frequency should be required?

I knew absolutely nothing about the SENT interface but 1 google search on "SENT interface" got me adequate resources. The first was the Wikipedia article which is good, and the second was from Renesas which was very good and detailed. Another one from On Semi gave the frequency as 30 kbits/second. The advantage of SENT is that the timing is given for each transmission by a very precise start / synchronisation pulse of 56 ticks. so as long as your timing does not vary within a transmission then it can vary over time (eg with temperature and other factors. Another NXP document I looked at gave 3 uS as the basic tick time (which roughly corresponds to 30KB/s as above). SO get onto Google - you'll get as much information as you need.

With SENT you can perform Digital data transmission at 30 kbits/s.
It is Point to point.
Its Clock drift error is less than 0.05us

SENT (Single Edge Nibble Transmission) is a serial communication interface used in automotive applications for transmitting sensor data. It is a simple, low-cost interface that uses a single wire to transmit data at a low frequency (usually around 10 kHz).

The trend for SENT interfaces is to transmit data at higher frequencies in order to increase the amount of data that can be transmitted and to reduce noise. Some newer SENT interfaces can transmit data at frequencies up to 100 kHz.

In general, the required frequency for a SENT interface depends on the specific application and the amount of data that needs to be transmitted. Higher frequencies can allow for faster transmission of data, but they may also be more susceptible to noise and interference. It is important to carefully consider the requirements of the application and the trade-offs between speed and reliability when selecting the appropriate frequency for a SENT interface.
