Other Parts Discussed in Thread: ADS1282, LMK01801, LMK00101, LMK01000

Hi,

I use the 8 chips of ads1282 with 4.096M. I need to sample with 96 Hz so I make 96 frequency source to synchronic the ads1282 on the pluse-sync mode. I found it takes

too time to sync  about 10ms .

would you please give me some good idea

thanks

Jack

    Hi Jack,

    You could use clock divider to divide-down the 4.096 MHz sample clock clock down to 100 Hz and 1:8 fanout buffer to your ADCs.  Since this requires large divide value, you may need to cascade two dividers devices. 

    See LMK01000 and LMK01801 divider/buffers chips and LMK00101 CMOS fanout devices.  These are high performance devices (probably overkill for your application), but it should give you an idea of the functionality you're looking for.

    Regards,
