Other Parts Discussed in Thread: TDA4VL
Dear TI expert
We use TDA4VL as our project solution and connect the SPI interface to UPID(Super sonic Sensor) directly .
The SPI CLK frequency 10MHz.
And according to the HW test, we found that the Tids(SDO impedance after CSN High) can't meet the requirement from datasheet. The maximum value from datasheet is 200ns and the actual measured of Tids value is 24uS/42uS( two samples).
The SPI interface is connect to UPID's SPI interface directly. Can we just config the register to change the Tids value?
