CS5361 114 dB, 192 kHz, Multi-Bit Audio A/D Converter Features General Description The CS5361 is a complete analog-to-digital converter for z Advanced Multi-bit Delta-sigma Architecture digital audio systems. It performs sampling, analog-to- digital conversion, and anti-alias filtering. The CS5361 z 24-bit Conversion generates 24-bit values for both left and right inputs in z 114 dB Dynamic Range serial form at sample rates up to 192 kHz per channel. z -105 dB THD+N The CS5361 uses a 5th-order, multi-bit, delta-sigma modulator followed by digital filtering and decimation. z System Sampling Rates up to 192 kHz This removes the need for an external anti-alias filter. The ADC uses a differential architecture which provides z 135 mW Power Consumption excellent noise rejection. z High-pass Filter and DC Offset Calibration The CS5361 is ideal for audio systems requiring wide dy- namic range, negligible distortion, and low noise. These z Supports Logic Levels Between 5 and 2.5 V applications include A/V receivers, DVD-R, CD-R, digital z Differential Analog Architecture mixing consoles, and effects processors. z Overflow Detection ORDERING INFORMATION CS5361-KSZ -10 to 70C 24-pin SOIC Lead Free z Pin-compatible with the CS5381 CS5361-KZZ -10 to 70C 24-pin TSSOP Lead Free CS5361-DZZ -40 to 85C 24-pin TSSOP Lead Free CDB5361 Evaluation Board SCLK VQ OVFL V LRCK SDOUT MCLK REFGND L RST FILT+ Serial Output Interface Voltage Reference 2 I S/LJ M/S AINL- HPF + Digital High LP Filter Decimation Pass MDIV AINL+ - Filter Filter S/H DAC AINR- Digital High + MODE0 LP Filter Decimation Pass AINR+ - Filter MODE1 Filter S/H DAC Copyright Cirrus Logic, Inc. 2005 FEB 05 CS5361 TABLE OF CONTENTS 1.0 CHARACTERISTICS AND SPECIFICATIONS ...................................................................... 4 Specified Operating Conditions ................................................................................................ 4 Absolute Maximum Ratings ...................................................................................................... 4 Analog Characteristics (CS5361-KSZ/KZZ).............................................................................. 5 Analog Characteristics (CS5361-DZZ) ..................................................................................... 6 Digital Filter Characteristics ...................................................................................................... 7 DC Electrical Characteristics .................................................................................................. 10 Digital Characteristics ............................................................................................................. 10 Switching Characteristics - Serial Audio Port.......................................................................... 11 2.0 PIN DESCRIPTIONS ............................................................................................................ 14 3.0 TYPICAL CONNECTION DIAGRAM .................................................................................... 15 4.0 APPLICATIONS .................................................................................................................... 16 4.1 Operational Mode/Sample Rate Range Select ................................................................ 16 4.2 System Clocking .............................................................................................................. 16 4.2.1 Slave Mode ......................................................................................................... 16 4.2.2 Master Mode ....................................................................................................... 17 4.3 Power-up Sequence ........................................................................................................ 18 4.4 Analog Connections .........................................................................................................18 4.5 High-pass Filter and DC Offset Calibration ..................................................................... 19 4.6 Overflow Detection ........................................................................................................... 19 4.6.1 OVFL Output Timing ........................................................................................... 19 4.7 Grounding and Power Supply Decoupling ....................................................................... 19 4.8 Synchronization of Multiple Devices ................................................................................ 19 5.0 PARAMETER DEFINITIONS ................................................................................................ 20 6.0 PACKAGE DIMENSIONS .................................................................................................. 21 7.0 REVISION HISTORY ............................................................................................................ 23 2 DS467F2
