10.Data clocked in on rising clock edge
Each channel in the AM55-0024 is independently
controllable with a 3 wire serial interface: Clock, Data,
and Latch Enable. These lines can be shared based on
application requirements.
device is controlled with a 6 bit word, enabling the
selection of 64 possible states. The highest gain state is
'000000', and the lowest is '111111'. The sequence for
shifting the data is as follows: Present data (Least sig-
nificant bit first), strobe clock, repeat until 6 bits have
been presented and clocked, then strobe the latch enable
line, which implements the state change.
