CS53L30 Datasheet PDF - Cirrus Logic

General Description
   The CS53L30 is a high-performance, low-power, quad-channel ADC. It is designed for use in multiple-mic applications while consuming minimal board space and power

Analog Input and ADC Features
◾ 91-dB dynamic range (A-weighted) @ 0-dB gain
◾ –84-dB THD+N @ 0-dB gain
◾ Four fully differential inputs: Four analog mic/line inputs
◾ Four analog programmable gain amplifiers
   ◾ –6 to +12 dB, in 0.5-dB steps
   ◾ +10 or +20 dB boost for mic input
◾ Four mic bias generators
◾ MUTE pin for quick mic mute and programmable quick
   power down

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-kHz
   sample rate data on a single TDM line.

System Features
◾ 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-kHz audio sample rates
◾ Master or Slave Mode. Clock dividers can be used to
   generate common audio clocks from single-master clock
   input.
◾ Low power consumption
◾ Less than 4.5-mW stereo (16 kHz) analog mic record
◾ Less than 2.5-mW mono (8 kHz) analog mic record
◾ Selectable mic bias and digital interface logic voltages
◾ High-speed (400-kHz) I²C control port
◾ Available in 30-ball WLCSP and 32-pin QFN

APPLICATIONs
◾ Voice-recognition systems
◾ Advanced headsets and telephony systems
◾ Voice recorders
◾ Digital cameras and video cameras
