4. APPLICATIONS
4.1
Sample Rate Range/Operational Mode Detect
The device operates in one of three operational modes. The allowed sample rate range in each mode is
auto-detected.
The CS4352 will auto-detect the correct mode when the input sample rate (Fs), defined by the LRCK fre-
quency, falls within one of the ranges illustrated in Table 1. Sample rates outside the specified range for
each mode are not supported.
Table 1. CS4352 Auto-Detect
4.2
System Clocking
The device requires external generation of the master (MCLK), left/right (LRCK) and serial (SCLK) clocks.
The left/right clock, defined also as the input sample rate (Fs), must be synchronously derived from the
MCLK according to specified ratios. The specified ratios of MCLK to LRCK, along with several standard au-
dio sample rates and the required MCLK frequency, are illustrated in Tables 2-4.
Refer to Section 4.3 for the required SCLK timing associated with the selected Digital Interface Format and
to “Switching Specifications - Serial Audio Interface” on page 8 for the maximum allowed clock frequencies.
