AD9937
STANDBY SEQUENCE
The following sequence is recommended when the AD9937 is
put into standby operation. (Refer to Figure 38 for each step.)
1. Write a 0 to the OUTCONT_REG register (addr 0x01).
2. Write a 0 to the DIG_STBY and AFE_STBY registers
(addr 0x02). This will put the digital and analog circuits into
the standby operating mode.
