PLL Operation
The PLL has been designed to accommodate a wide range
of sample rates. The SRR0 and SRR1 pins are used to
congure the PLL for the intended sample rate range.
Table 2 summarizes the sample clock ranges available
to the user.
Serial Test Patterns
To facilitate testing of the serial interface, three test patterns
are selectable via pins PAT0 and PAT1. The available test
patterns are described in Table 3. A K28.5 comma may be
used as a fourth test pattern by requesting synchronization
through the SYNC+/SYNC– pins.
