Dear All,
I have been using external clock for MCBSP. FSX signal has been generated on
every DXR2XSR shift. I have been interfacing McBSP with HI-15530.
FSX has been generated but it has not been activating the encoder. Because
we are applying FSX Pulse directly on Encoder Enable pin of HI-15530. I have
measured Voltage level of FSX signal through Volt Meter. It was something
round about
98.0 mV. IC HI-15530 has been tested by connecting/disconnecting 5V supply
sequence wise on Encoder Enable Pin. Encoder was enable and *send
data*signal was generated. but this procedure was just for checking
the HI-15530.
We can not apply this method in normal operation of HI-15530.
The conclusion is that Voltage level of FSX signal is not sufficient to
drive Encoder Enable pin of HI-15530.
What could be the solution for this type of problem.

Shahzad Ahmed
