hi wan,
in case you haven't seen this,
there are some sync pulse guidelines in casper memo 24:
"Sync Pulse Usage - July 2008 (Henry Chen, et al)"

best wishes,

Hi:
After reading the memo of sync pulse, I still feel a little bit confused.
I use a PFB in my design. So I guess I have to include the order of PFB
into the calculation.
The order of PFB is 2. But there are two stage in the PFB. There are 2
taps in the second stage as well. So I set the reorder to 2 or 4?
For the FFT, there are 2 order-2 reorder block in the bi_real_unscr_4x,
so I recorder order should be 4.
Its FFT unscrambler use an 8 order block. So its order is 8.
So the sync period of FFT is 4*8*512/4 = 4096. Is this right?
What I could not understand is the PFB. I use 2 order or 4?
Thanks
Wan
