3.0 APPLICATIONS
3.1 Sample Rate Range/Operational Mode Select
The device operates in one of two operational modes. Operation in either mode depends on the input sam-
ple rate and the ratio of the master clock to the left/right clock (see section 3.2). Sample rates outside the
specified range for each mode are not supported.
3.2 System Clocking
The device requires external generation of the master (MCLK) and left/right (LRCK) clocks. The device
also requires external generation of the serial clock (SCLK) if the internal serial clock is not used. The
LRCK, defined also as the input sample rate F
specified ratios. The specified ratios of MCLK to LRCK, along with several standard audio sample rates
and the required MCLK frequency, are illustrated in Tables 2-3.
*Requires MCLKDIV bit = 1 in the Mode Control 2 register (address 0Bh).
