Figure 14. Recommended Power-Up Sequence
Recommended Power-Up Sequence
When the AD9848 and AD9849 are powered up, the following sequence is recommended (refer to Figure 14 for each step).
1. Turn on power supplies for AD9848/AD9849.
2. Apply the master clock input CLI, VD, and HD.
3. The Precision Timing core must be reset by writing a “0” to the TGCORE_RSTB register (addr x026) followed by writing
a “l(fā)” to the TGCORE_RSTB register. This will start the internal timing core operation.
4. Write a “1” to the PREVENTUPDATE register (addr x01B). This will prevent the updating of the serial register data.
5. Write to desired registers to configure high speed timing and horizontal timing.
6. Write a “1” to the OUT_CONT register (addr x016). This will allow the outputs to become active after the next VD/HD
rising edge.
7. Write a “0” to the PREVENTUPDATE register (addr x01B). This will allow the serial information to be updated at next
VD/HD falling edge.
8. The next VD/HD falling edge allows register updates to occur, including OUT_CONT, which enables all clock outputs.
