2. FUNCTIONAL DESCRIPTION
A clock input at CLKIN is converted to an alternate clock rate available on CLKOUT1. A higher multiple-rate clock
also is available on CLKOUT2. Additionally, an 8kHz clock locked to CLKIN is always available at the SYNCOUT
pin. The SEL pin controls clock-rate conversion selection.
2.1 Mode Select
The SEL pin is used to select the operating frequencies.
modes of the DS21600, DS21602, and DS21604.
Table 2-A. Frequency Conversions (MHz)
2.2 Frame-Sync Input
In all cases, CLKOUT1 and CLKOUT2 are frequency-locked to CLKIN. CLKOUT1, CLKOUT2, and SYNCOUT
are phased-locked to SYNCIN when SYNCIN is asserted. 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.
