Recommended Power-Up Sequence
1. Hold RESET low until the power supply,MCLK, and LRCK are stable. In this state, the Control Port is
2. Bring RESET high. The device will remain in a low power state with the PDN bit set by default. The con-
3. The desired register settings can be loaded while the PDN bit remains set.
4. Clear the PDN bit to initiate the power-up sequence.
System Clocking
The CS5345 will operate at sampling frequencies from 4 kHz to 200 kHz. This range is divided into three
speed modes as shown in
Master Clock
MCLK/LRCK must maintain an integer ratio as shown in
frequency at which audio samples for each channel are clocked out of the device. The FM bits (See
