Digital Processing Features
- Volume control, mute, programmable high-pass filter, noise gate
- Two digital mic (DMIC) interfaces
Digital Output Features
- Two DMIC SCLK generators
- Four-channel I2S output or TDM output. Four CS53L30s can be used to output 16 channels of 24-bit 16-k Hz sample rate data on a single TDM line.
- Native (no PLL required) support for 6-/12-MHz, 6.144-/ 12.288-MHz, 5.6448-/11.2896-MHz, or 19.2-MHz master clock rates and 8- to 48-k Hz audio sample rates
- Master or Slave Mode. Clock dividers can be used to generate mon audio clocks from single-master clock input.
