USER-CONFIGURABLE BUILT-IN SELF-TEST (BIST)

Each channel of AD6654 includes a BIST block. The BIST,

along with an internal test signal (pseudo random test input

signal), can be used to generate a signature. This signature can

be compared with a known good device and an untested device

to see if the untested device is functional.

BIST timer bits in the BIST control register can be programmed

with a timer value that determines the number of clock cycles

that the output of the channels (output of AGC) have

accumulated. When the disable signature generation bit is

written with Logic 0, the BIST timer is counted down and a

signature register is written with the accumulated output of the

AD6654 channel.

When the BIST timer expires, the signature register for I and Q

paths can be read back to compare it with the signature register

from a known good device.
