Hai all, i am working in a card which involves SPI communication between ADSP-BF531 and ADSP-BF533.when i perform SPI Master mode communication(Transmission) on BF531,i am not able to see the SPI clock on the pin. i am able to get the SPI clock if i run the code on BF533(with header file and ldf file modification ). i am bit confused of this pe

Hi, I wish to configure my BF531 to work at max CCLK of 400MHz and max SCLK of 133MHz. Two options :- 1. I can use a 8MHz crystal. Set DF bit to 1. Set the multiplier (MSEL[5:0]) to 50 to get VCO = 400MHz. Set Core Clock Divider to 1 (CSEL[1:0]


Which one of the lowest cost video decoder chip is suitable with BF531?

Hi, I plan to make my own board based on BF531. I want to use a low cost video decoder chip such as ADV7180, but BF533 Ez-Kit Lite uses ADV7183. ADV7183 has 3 A/D converter and runs with 27 MHz crystal. ADV7180 has only one A/D converter and runs with 28.6363 MHz crystal. (I should use different crystals for video chip and the DSP.) And, TVP5146 from TI is also compatible with BF531...

Hi, I wish to configure my BF531 to work at max CCLK of 400MHz and max SCLK of 133MHz. Two options :- 1. I can use a 8MHz crystal. Set DF bit to 1. Set the multiplier (MSEL[5:0]) to 50 to get VCO = 400MHz. Set Core Clock Divider to 1 (CSEL[1:0] = 00) to get CCLK = 400MHz. Set System Clock Divider to 3 (SSEL[3:0] = 0011) to get SCLK = 133.33MHz. I think SCLK will be by itself rounded off
