• Manufacturer: Cirrus Logic, Inc.

4. APPLICATIONS
4.1
4.1.1
The device operates in one of four operational modes determined by the Mode pins in Stand-alone mode.
Sample rates outside the specified range for each mode are not supported.
4.1.2
The device operates in one of three operational modes determined by the FM bits (see section 6.1.4) in
Control Port mode. Sample rates outside the specified range for each mode are not supported.
4.2
The device requires external generation of the master (MCLK), left/right (LRCK) and serial (SCLK) clocks.
The LRCK, defined also as the input sample rate (F
according to 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 3-5.
