2.1 Migrating from CS495xx(2) to CS4970x4
CS4970x4 was designed to provide an easy upgrade path from the CS495xx and CS4953x. Although 144-pin
versions of the two devices are virtually identical with respect to external system connection, there are some
small differences the hardware designer should be aware of:
The PLL supply voltage on the CS4970x4 is 3.3V vs. 1.8V on the CS495xx.
The PLL filter topology is simpler when using the CS4970x4 rather than the CS495xx.
The CS4970x4 adds support for Time-division multiplexing (TDM) mode on both audio input and output
ports.
The CS4970x4 does not support external static random access memory (SRAM) operation.
The CS4970x4 external Synchronous dynamic random access memory (SDRAM) bus speed is fixed at
150 MHz vs. the 120 MHz maximum bus speed for the CS495xx. Some firmware modules also support a
75 MHz CS4970x4 SDRAM bus speed. Refer to AN304 for details.
The CS4970x4 CLKOUT pin can output XTALI or XTALI/2. The CS495xx can only output XTALI.

available as a separate post-processing module that is described in the application note AN288PPI.
3. The indicated HD audio decoder algorithms require external SDRAM. Consult your Cirrus Logic FAE for the recommended
SDRAM size for your design.
