FUNCTIONAL DESCRIPTION
A clock input at CLKIN is converted to various clocks available on CLKOUT1 and CLKOUT2.
Additionally, an 8 kHz clock locked to CLKIN and SYNCIN (if present) is always available at the
SYNCOUT pin. The pulse width of the SYNCOUT, is selectable. It can be one or one half the clock
period of CLKIN, centered on the rising edge of CLKIN. Pins P1 through P4 are used to select the
various clock rates and operational modes. Table 3-1 and Table 3-2 list the various operational modes of
the DS21610.
CLKIN, CLKOUT1 and CLOCKOUT2 are always frequency locked. They can all be phase locked to a
system frame sync pulse. A frame sync pulse applied to SYNCIN will cause CLKIN and CLKOUT1 and
CLKOUT2 to be phased locked to that sync pulse. This will cause the clocks to have a fixed alignment at
the frame sync boundries. The signal applied to SYNCIN can be 8 kHz or some integer sub-rate such as
1, 2 or 4 kHz. Phase synchronization will occur within a maximum of 500ms when SYNCIN is 8 kHz.
