EXTERNAL SYNCHRONIZATION (MASTER MODE)
External synchronization can be applied to synchronize the VD
and HD signals by applying an external pulse on the
SYNC/GATE (Pin 45) pin for master mode operation. The
SYNC/GATE pin is configured as an external SYNC input for
master mode operation by setting the SLAVE_MODE register
(Address 0xD6) = 0 (the AD9929 defaults to slave mode at
power-up).
SYNCCNT (Address 0x0A) and SYNCPOL (Address 0x01) are
the only two registers used for configuring the AD9929 for
external synchronization. The SYNCPOL is a 1-bit register used
for configuring the SYNC input as either active low or active
high. The AD9929 defaults to active low at power-up. The
function of the SYNCCNT register is described in Table 17.
Figure 20 and Figure 21 provide two examples of external
synchronization with SYNCPOL = 0.
