I've attached the crystal that was used on the evaluation board, however you can use other crystals as long as you re-calculate the load capacitors based on the following application note

Hi,
because a lot of these examples were moved from earlier releases of VisualDSP++, you may find that the way the Interrupts are handled by the LDF does not match the more recent default LDFs, such as in this case - the example just has a single block…
Hi Poornima,
A brief query with regards to the required XTAL.
The one we've purchased from RS electronics : ABM8IG-28.63636MHZ-18-D2Y-T
According to App notes AN-1260 - and the typical connection diagram XTAL circuit
C1 = C2 = 22pF , Rdamp = 82…
Hi Shafi,
Place an SSYNC instruction after you write to DMA4_IRQ_STATUS register (before performing RTI). This would ensure that the peripheral releases the request before the RTI is executed. Another best thing is to perform a dummy PAB access before…
You're right. The RTI noise and the RTO noise are equal for an op amp when you have a voltage follower (unity gain feedback). Otherwise you use the noise gain (1/beta) to translate between RTI and RTO.
Ok, propably should use ISR=>IVT and the title of this thread should be something else too, but don't know how to edit that afterwards,
Right now the problem is around the interrupt handler(s).
What could be the official way of creating one?
Hello,
I have a question of "Frequency Stability" specification of video decoder devices.--------------------------------SYSTEM CLOCK AND CRYSTAL Nominal Frequency 28.63636 MHz Frequency Stability ±50 ppm--------------------------------I think…
The first of the four interrupt vector instructions should execute a "PUSH STS". This saves the value of MODE1, ASTAT[xy]. When the RTI instructions is executed to return from the interrupt this pops STS automatically and restores MODE1 and…
With L=50 and lower fc High Pass filter, I have mostly the same Re and Im data when calibrating:
