How do you calculate the serial and parallel update rates which appear on the product web-pages and datasheets?
The way to calculate the update rates are:
For serial interface:
For all the 16 bits (20ns * 16) = 320ns ( Clock speed = 20ns per bit )
Output Voltage settling time = 50 ns
Sync Rising Edge = 5 ns
Sync High Time = 30 ns
Total delay = 1/405ns = 2.467MSPS
For parallel interface:
CS Min Hi = 7ns
CS low time = 10ns
Output Voltage settling time = 30 ns
Total Delay = 1/47ns = 21.3MSPS
