STANDBY MODE OPERATION
Recommended Standby Mode Sequence
When the AD9898 is going into standby operation, the following
sequence is recommended. (Refer to Figure 52 for each step.)
1. Program OUTCONT_REG (Addr 0x05) = 0. This will
2. Program registers AFESTBY (Addr 0x05) = 0 and DIGSTBY
REV. 0
assert the internal OUTCONT signal LO causing all digital
outputs to become disabled.
(Addr 0x05) = 0. The AD9898 is then in standby operation.
