AD9082 Reset Timing

Question

Hello, 
 We are using the no-OS library and have good JESD links. The DAC and ADC are working fine. We have a boot time requirement we are trying to meet, and the no-OS API function adi_ad9081_device_reset() the reset sequency is quite long: 
 
 #define AD9081_API_HW_RESET_LOW 600000 
 #define AD9081_API_RESET_WAIT 500000 
 
 I searched through the UG and datasheet but could not find any reset pin timing information. My apologies if I just missed it. Is there any reset timing information available for the AD9082? 
 
 Thanks! and best regards,

Hi Mark, 
 The minimum RESETB hold time required to trigger a device reset is specified in Table 18 of the AD9081 datasheet. It appears that this information was inadvertently omitted from the AD9082 datasheet. 
 If you are looking for the reset-to-ready time, that parameter is not specified in the datasheet/userguide and would need to be characterized and validated within your specific system environment. 
 Please let me know if you have any questions.)
