@Sudhir,Apart from IIS3DWB, almost all the MEMS Accelerometers from ST are bandwidth limited to 400Hz except 2-3. I have had to do the detailed comparison of all currently active MEMS accelerometers from ST & found only a few with Noise Density less ...

For any Offboard SPI communication above 1Mhz Clock frequency & beyong 0.5m cable length, always prefer a Differential signaling. Some super cheap options are: AM26C31/32 differential driver (31) & receiver (32) pair from TI, which costs less than 1....
