CS4353
4.2
Sample Rate Range/Operational Mode Detect
The CS4353 operates in one of three operational modes. The device will auto-detect the correct mode when
the input sample rate (Fs), defined by the LRCK frequency, falls within one of the ranges illustrated in
Table 2. Sample rates outside the specified range for each mode are not supported. In addition to a valid
LRCK frequency, a valid serial clock (SCLK) and master clock (MCLK) must also be applied to the device
for speed mode auto-detection; see Figure 9.
Table 2. CS4353 Operational Mode Auto-Detect
4.3
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 signal according to specified ratios. The specified ratios of MCLK to LRCK, along with several stan-
dard audio sample rates and the required MCLK frequency, are illustrated in Tables 3-5.
Refer to Section 4.4 for the required SCLK timing associated with the selected Digital Interface Format and
to “Switching Specifications - Serial Audio Interface” on page 9 for the maximum allowed clock frequencies.
