• The PLL supply voltage on the CS4953xx is 3.3V vs. 1.8V on the CS495xx(2).
• The PLL filter topology is simpler when using the CS4953xx rather than the CS495xx(2).
• The CS4953xx adds support for 6-channel DSD input.
• The CS4953xx adds support for TDM mode on both audio input and output ports.
• The CS4953xx does not support external SRAM operation.
• The CS4953xx external SDRAM bus speed is fixed at 150 MHz vs. the 120 MHz max bus speed for the
