Hi,

I want to know the range of pulse repetition frequency that can be supported by LM96570. I mean, how much frequency signal supported at Tx_En pin.

please help me. Thank you.

PFR<=1/(DEL+n*F0) , where

PRF - pulse repetition frequency

DEL - programmed delay

n - programmed number of pulses

F0 - TX frequency

Regards,

Mariusz

Thanks for your reply.

I request you to mention PRF range supported by LM96570 IC. like max center frequency supported by lm96570 is upto 80 Mhz.

Sorry sir, I did not understand your formula....

can you see once my understanding about PRF. plz let me know if wrong.

prf(hz)=1 / (Tx_en(ON)+Tx_en(OFF))

Tx_en(ON)=n*(1/F0)

Tx_en(OFF)= 2*d/c

d - depth of scan

c - avg sound velocity (typically 1540 m/s)

Hi,

In fact there is misstype error in the formula I gave you. It should be like this:

PRF<=1/(DEL+n/F0)

The above formula gives you the maximum possible PRF. However, in medical applications you should follow the physics and calculate PRF exactly as you did.

Regards,

Mariusz
