AD9929
STANDBY MODE OPERATION
Recommended Standby Mode Sequence
When the AD9929 is going into standby operation, the follow-
ing sequence is recommended (refer to Figure 67 for each step).
Rev. A | Page 56 of 64
1.
Program OUTCONT_REG (Address 0x05) = 0. This
asserts the internal OUTCONT signal low, causing all
digital outputs to become disabled.
2.
Program registers AFESTBY (Address 0x05) = 0 and
DIGSTBY (Address 0x05) = 0. The AD9929 is now in
standby operation.
3.
When ready to come out of standby operation, program
register DIGSTBY (Address 0x05) = 1 and register
AFESTBY (Address 0x05) = 1.
4.
Program necessary control registers.
5.
Program control register MODE (Address 0x0A) = 0. This
selects Mode_A operation.
6.
Program register OUTCONT_REG (Address 0x05) = 1.
This asserts the internal OUTCONT signal high, causing
all digital outputs to become active.
