DS21610 3.3V/5V Clock Rate Adapter
5 of 15
2. FUNCTIONAL DESCRIPTION
A clock input at CLKIN is converted to various clocks available on CLKOUT1 and CLKOUT2. Additionally, an 8kHz
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 to P4 are used to select the various clock rates and operational modes.
Table 2-A
and
Table 2-B
list the various operational modes of the DS21610.
CLKIN, CLKOUT1, and CLCKOUT2 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 causes the clocks to have a fixed alignment at the frame-sync boundaries.
The signal applied to SYNCIN can be 8kHz or some integer subrate such as 1kHz, 2kHz, or 4kHz. Phase
synchronization occurs within a maximum of 50ms when SYNCIN is 8kHz.
