COREN and DSTCTL Input Read
COREN and DSTCTL are monitored at intervals of one input clock cycle, and their logic states can be changed at any
time. During sync detection, a change in input state occurs if either pin remains steady for four successive clock intervals
as shown in figure 4.
Figure 4. Input read during sync detection
After sync detection a change in input state occurs if either COREN or DSTCTL remains steady for four successive input
data blocks as shown in figure 5.

Design Notes
Oscillator specifications are shown in table 2 and figure 6. Oscillator stabilization delay is shown in figure 7. Reset input
circuitry is shown in figure 8. Supply rise time versus RES delay is shown in figure 9.
