Output Enable/Disable
The CY29947 features a control input to enable or disable the
outputs. This data is latched on the falling edge of the input
clock. When SYNC_OE is asserted LOW, the outputs are dis-
abled in a LOW state. When SYNC_OE is set HIGH, the out-
puts are enabled as shown in
Figure 1
