H-Counter Synchronization
The H-Counter reset occurs on the sixth CLI rising edge following
the HD falling edge. The
PxGA
steering is synchronized with the
reset of the internal H-Counter (see Figure 13).
POWER-UP PROCEDURE
Recommended Power-Up Sequence
When the AD9847 is powered up, the following sequence is
recommended (refer to Figure 14 for each step).
1. Turn on power supplies for AD9847.
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 (Address x026) followed by writ-
ing a “l(fā)” to the TGCORE_RSTB Register. This will start the
internal timing core operation. Next, initialize the internal

NOTES
1. INTERNAL H-COUNTER IS RESET ON THE SIXTH CLI RISING EDGE FOLLOWING THE HD FALLING EDGE.
2.
PxGA
STEERING IS SYNCHRONIZED WITH THE RESET OF THE INTERNAL H-COUNTER (MOSAIC SEPARATE MODE IS SHOWN).
3. VD FALLING EDGE SHOULD OCCUR ONE CLOCK CYCLE BEFORE HD FALLING EDGE FOR PROPER
PxGA
LINE SYNCHRONIZATION.

circuitry by first writing “110101” or “53” decimal to the
INITIAL1 Register (Address x020). Finally, write “000100”
or “4” decimal to the INITIAL2 Register (Address x00F).
4. Write a “1” to the PREVENTUPDATE Register (Address x019).
This will prevent the updating of the serial register data.
5. Write to the desired registers to configure high speed timing
and horizontal timing.
6. Write a “1” to the OUT_CONT Register (Address x016).
This will allow the outputs to become active after the next
VD/HD rising edge.
7. Write a “0” to the PREVENTUPDATE Register (Address x019).
This will allow the serial information to be updated at the
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.
