It performs sampling, analog-to-digital conversion, and anti-alias filtering, generating24-bit values for both left and right inputs in serial format sample rates up to 200 kHz per channel. </p><p>The CS5341 uses a 5th-order, multi-bit Delta-Sigmamodulator followed by digital filtering and decimation,which removes the need for an external anti-alias filter. </p><p>The CS5341 is available in a 16-pin TSSOP packagefor Commercial (-10 to +70 C) and Automotive grades(-40 to +85 C). The CDB5341 Customer Demonstra-tion Board is also available for device evaluation andimplementation suggestions. Please refer to OrderingInformation on page 22 for complete orderinginformation.</p><p>The CS5341 is ideal for audio systems requiring widedynamic range, negligible distortion and low noise, suchas set-top boxes, DVD-karaoke players, DVD record-ers, A/V receivers, and automotive applications.</p><p>High-Pass Filter</p><p>Low-Latency Digital Filters</p><p>High-Pass Filter</p><p>Seria</p><p>l Por</p><p>t</p><p>VA3.3 V to 5 V</p><p>Internal Reference Voltages</p><p>Switch-CapADC</p><p>VD3.3 V to 5 V</p><p>VL1.8 V to 5 V</p><p>Auto-detect MCLK Divider</p><p>Slave Mode Auto-detect</p><p>Master Clock</p><p>Reset</p><p>Single-Ended Analog Input</p><p>Low-Latency Digital Filters</p><p>Switch-CapADC</p><p>Mode Configuration</p><p>Single-Ended Analog Input</p><p>SCLK</p><p>LRCK</p><p>SDOUT</p><p>M0</p><p>M1</p><p>FILT+</p><p>VQ</p><p>AINR</p><p>AINL</p><p>Copyright Cirrus Logic, Inc. 2008(All Rights Reserved)http://www.cirrus.com</p><p>March '08DS564F2</p><p>http://www.cirrus.comhttp://www.cirrus.com</p></li><li><p>CS5341Confidential Draft</p><p>3/11/08</p><p>TABLE OF CONTENTS1.
