OMAP3530 MCBSP

Other Parts Discussed in Thread: OMAP3530

Hi, On our OMAP3530 based custom board we are trying to generate Clock on MCBSP with 2700bps data rate.But we were unable to do it after gone through details of the clock source for MCBSP. Can we generate the clock for that data rate (2.7KHz) with MCBSP?

Now we are generating clock on GPIO pins based on the timer tick.I'm attaching the source file

5342.timer_test.c

7587.timer_app.c

timer_test.c is the code for toggling gpio for 2700Hz

timer_app.c is the user space application to enable timer.

we are facing problem with clock jitter. it is varying between 2695HZ and 2710HZ. We are looking  exact 2700HZ clock on our application.

My clock tree is

SystemClock = 19.2 MHz

DPLL_MULT_VALUE = 242

DPLL_DIV_VALUE = 13

CORE_DPLL_CLK = 663.771 MHz

CORE_CLK = 331.8855 MHz

L3_CLK = 165.9427 MHz

How can we generate 2700HZ clock with MCBSP5? 

Thank You
