3. APPLICATIONS

3.1

Upgrading from the CS4341 to the CS4341A

The CS4341A is pin and functionally compatible with all CS4341 designs, operating at the standard audio

sample rates, that use pin 3 as a serial clock input. In addition to the features of the CS4341, the CS4341A

supports standard sample rates up to 192 kHz, as well as automatic mode detection for sample rates be-

tween 4 and 200 kHz. The automatic speed mode detection feature allows sample rate changes between

single, double and quad-speed modes without external intervention.

The CS4341A does not support an internal serial clock mode, sample rates between 50 kHz and 84 kHz

(unless otherwise stated), or 2.7 V operation as does the CS4341.

3.2

Sample Rate Range/Operational Mode Detect

The device operates in one of three operational modes. The allowed sample rate range in each mode will

depend on whether the Auto-Detect Defeat bit is enabled/disabled.

3.2.1

Auto-Detect Enabled

The Auto-Detect feature is enabled by default in the control port register 5.1. In this state, the

CS4341A 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 1. Sample rates outside the specified

range for each mode are not supported.

3.2.2

Auto-Detect Disabled

The Auto-Detect feature can be defeated via the control port register 5.1. In this state, the CS4341A

will not auto-detect the correct mode based on the input sample rate (Fs). The operational mode

must be set appropriately if Fs falls within one of the ranges illustrated in Table 2. Please refer to

section 5.1.1 for implementation details. Sample rates outside the specified range for each mode

are not supported.
